DESCRIPTION
You can use this cmdlet for one mailbox at a time. To perform bulk management,
you can pipeline the output of various Get- cmdlets (for example, the
Get-Mailbox or Get-User cmdlets) and configure several mailboxes in a
single-line command. You can also use the Set-Mailbox cmdlet in scripts.
You need to be assigned permissions before you can run this cmdlet. Although
this topic lists all parameters for the cmdlet, you may not have access to some
parameters if they're not included in the permissions assigned to you. To find
the permissions required to run any cmdlet or parameter in your organization,
see Find the permissions required to run any Exchange cmdlet.
EXAMPLES
EXAMPLE 1
PowerShell Copy
Set-Mailbox -Identity "John Woods" -DeliverToMailboxAndForward $true -ForwardingSMTPAddress manuel@contoso.com
This example delivers John Woods's email messages to John's mailbox and also
forwards them to Manuel Oliveira's (manuel@contoso.com) mailbox.
EXAMPLE 2
PowerShell Copy
Get-Mailbox -OrganizationalUnit "Marketing" | Set-Mailbox -UseDatabaseQuotaDefaults $false -IssueWarningQuota 200MB -ProhibitSendQuota 250MB -ProhibitSendReceiveQuota 280MB
This example uses the Get-Mailbox cmdlet to find all the mailboxes in the
Marketing organizational unit, and then uses the Set-Mailbox cmdlet to configure
these mailboxes. The custom warning, prohibit send, and prohibit send and
receive limits are set to 200 megabytes (MB), 250 MB, and 280 MB respectively,
and the mailbox database's default limits are ignored.
EXAMPLE 3
PowerShell Copy
Get-User -Filter "Department -eq 'Customer Service'" | Set-Mailbox -MaxSendSize 2MB
This example uses the Get-User command to find all users in the Customer Service
department, and then uses the Set-Mailbox command to change the maximum message
size for sending messages to 2 MB.
EXAMPLE 4
PowerShell Copy
Set-Mailbox John@contoso.com -MailTipTranslations ("FR: C'est la langue française", "CHT: 這是漢語語言")
This example sets the MailTip translation in French and Chinese.
EXAMPLE 5
PowerShell Copy
$password = Read-Host "Enter password" -AsSecureString
Set-Mailbox florencef -Password $password -ResetPasswordOnNextLogon $true
In on-premises Exchange, this example resets the password for Florence Flipo's
mailbox. The next time she signs in to her mailbox, she'll have to change her
password.
EXAMPLE 6
PowerShell Copy
Set-Mailbox -Arbitration -Identity "SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c}" -MessageTracking $false
Set-Mailbox -Arbitration -Identity "SystemMailbox{1f05a927-b864-48a7-984d-95b1adfbfe2d}" -MessageTracking $true
This example removes the message tracking organization capability from the
arbitration mailbox named SystemMailbox{bb558c35-97f1-4cb9-8ff7-d53741dc928c}
and assigns it to an arbitration mailbox named
SystemMailbox{1f05a927-b864-48a7-984d-95b1adfbfe2d}.
EXAMPLE 7
PowerShell Copy
Set-Mailbox -Identity "John Woods" -EmailAddresses @{add="Jwoods@contoso.com"}
This example adds a secondary email address to John's mailbox.
EXAMPLE 8
PowerShell Copy
Set-Mailbox -Identity asraf@contoso.com -RemoveDelayReleaseHoldApplied
In Exchange Online, this example removes the delay hold that's applied to
Asraf's mailbox so an offboarding migration (that is, a mailbox migration from
Exchange Online back to on-premises Exchange) can continue successfully. For
more information about delay holds, see Managing mailboxes on delay hold.
PARAMETERS
-ACCEPTMESSAGESONLYFROM
The AcceptMessagesOnlyFrom parameter specifies who is allowed to send messages
to this recipient. Messages from other senders are rejected.
Valid values for this parameter are individual senders in your organization
(mailboxes, mail users, and mail contacts). You can use any value that uniquely
identifies the sender. For example:
* Name
* Alias
* Distinguished name (DN)
* Canonical DN
* Email address
* GUID
You can enter multiple senders separated by commas. To overwrite any existing
entries, use the following syntax: Sender1,Sender2,...SenderN. If the values
contain spaces or otherwise require quotation marks, use the following syntax:
"Sender1","Sender2",..."SenderN".
To add or remove senders without affecting other existing entries, use the
following syntax: @{Add="Sender1","Sender2"...; Remove="Sender3","Sender4"...}.
The senders you specify for this parameter are automatically copied to the
AcceptMessagesOnlyFromSendersOrMembers property. Therefore, you can't use the
AcceptMessagesOnlyFrom and AcceptMessagesOnlyFromSendersOrMembers parameters in
the same command.
By default, this parameter is blank ($null), which allows this recipient to

-ACCEPTMESSAGESONLYFROMDLMEMBERS
The AcceptMessagesOnlyFromDLMembers parameter specifies who is allowed to send
messages to this recipient. Messages from other senders are rejected.
Valid values for this parameter are groups in your organization (distribution
groups, mail-enabled security groups, and dynamic distribution groups).
Specifying a group means all members of the group are allowed to send messages
to this recipient. You can use any value that uniquely identifies the group. For
example:
* Name
* Alias
* Distinguished name (DN)
* Canonical DN
* Email address
* GUID
You can enter multiple groups separated by commas. To overwrite any existing
entries, use the following syntax: Group1,Group2,...GroupN. If the values
contain spaces or otherwise require quotation marks, use the following syntax:
"Group1","Group2",..."GroupN".
To add or remove groups without affecting other existing entries, use the
following syntax: @{Add="Group1","Group2"...; Remove="Group3","Group4"...}.
The groups you specify for this parameter are automatically copied to the

-ACCEPTMESSAGESONLYFROMSENDERSORMEMBERS
The AcceptMessagesOnlyFromSendersOrMembers parameter specifies who is allowed to
send messages to this recipient. Messages from other senders are rejected.
Valid values for this parameter are individual senders and groups in your
organization. Individual senders are mailboxes, mail users, and mail contacts.
Groups are distribution groups, mail-enabled security groups, and dynamic
distribution groups. Specifying a group means all members of the group are
allowed to send messages to this recipient.
To specify senders for this parameter, you can use any value that uniquely
identifies the sender. For example:
* Name
* Alias
* Distinguished name (DN)
* Canonical DN
* Email address
* GUID
You can enter multiple senders separated by commas. To overwrite any existing
entries, use the following syntax: Sender1,Sender2,...SenderN. If the values
contain spaces or otherwise require quotation marks, use the following syntax:

To add or remove individual senders or groups without affecting other existing
entries, use the AcceptMessagesOnlyFrom and AcceptMessageOnlyFromDLMembers
parameters.
The individual senders and groups you specify for this parameter are
automatically copied to the AcceptMessagesOnlyFrom and
AcceptMessagesOnlyFromDLMembers properties, respectively. Therefore, you can't
use the AcceptMessagesOnlyFromSendersOrMembers parameter and the
AcceptMessagesOnlyFrom or AcceptMessagesOnlyFromDLMembers parameters in the same
command.
By default, this parameter is blank ($null), which allows this recipient to

-ALIAS
The Alias parameter specifies the Exchange alias (also known as the mail
nickname) for the recipient. This value identifies the recipient as a
mail-enabled object, and shouldn't be confused with multiple email addresses for
the same recipient (also known as proxy addresses). A recipient can have only
one Alias value. The maximum length is 64 characters.
The Alias value can contain letters, numbers and the following characters:
* !, #, %, *, +, -, /, =, ?, ^, _, and ~.
* $, &, ', `, {, }, and | need to be escaped (for example -Alias what`'snew) or
the entire value enclosed in single quotation marks (for example, -Alias
'what'snew'). The & character is not supported in the Alias value for
Microsoft Entra Connect synchronization.
* Periods (.) must be surrounded by other valid characters (for example,
help.desk).
* Unicode characters U+00A1 to U+00FF.
When you create a recipient without specifying an email address, the Alias value
you specify is used to generate the primary email address (alias@domain).
Supported Unicode characters are mapped to best-fit US-ASCII text characters.
For example, U+00F6 (ö) is changed to oe in the primary email address.
If you don't use the Alias parameter when you create a recipient, the value of a
different required parameter is used for the Alias property value:
* Recipients with user accounts (for example, user mailboxes, and mail users):
The left side of the MicrosoftOnlineServicesID or UserPrincipalName parameter
is used. For example, helpdesk@contoso.onmicrosoft.com results in the Alias
property value helpdesk.
* Recipients without user accounts (for example, room mailboxes, mail contacts,
and distribution groups): The value of the Name parameter is used. Spaces are
removed and unsupported characters are converted to question marks (?).
If you modify the Alias value of an existing recipient, the primary email
address is automatically updated only in environments where the recipient is
subject to email address policies (the EmailAddressPolicyEnabled property is
True for the recipient).
The Alias parameter never generates or updates the primary email address of a
mail contact or a mail user.

* Destructive cmdlets (for example, Remove-* cmdlets) have a built-in pause
that forces you to acknowledge the command before proceeding. For these
cmdlets, you can skip the confirmation prompt by using this exact syntax:
-Confirm:$false.
* Most other cmdlets (for example, New-* and Set-* cmdlets) don't have a
built-in pause. For these cmdlets, specifying the Confirm switch without a

-DEFAULTAUDITSET
This parameter is available only in the cloud-based service.
The DefaultAuditSet parameter specifies whether to revert the mailbox operations

for the specified logon type. Valid values are:
* Admin: Reverts the mailbox operations to log for administrators back to the
default list of operations.
* Delegate: Reverts the mailbox operations to log for delegate users back to
the default list of operations.
* Owner: Reverts the mailbox operations to log for mailbox owners back to the
default list of operations.
With on-by-default mailbox auditing in the cloud-based service, a set of mailbox
operations are logged by default for each logon type. This list of operations is
managed by Microsoft, who will automatically add new operations to be audited
when they are released. If you change the list of mailbox operations for any
logon type (by using the AuditAdmin, AuditDelegate, or AuditOwner parameters),
any new mailbox operation released by Microsoft will not be audited; you'll need
to explicitly add new mailbox operations to the list of operations for a logon
type. Use this parameter to revert the mailbox back to the Microsoft-managed
list of mailbox operations that are audited for a logon type. For more
information about on-by-default mailbox auditing, see Manage mailbox auditing.

This parameter is available only in on-premises Exchange.
The DumpsterMessagesPerFolderCountReceiveQuota parameter specifies the maximum
number of messages that can be contained in each folder in the Recoverable Items
folder (called the dumpster in previous versions of Exchange). When a folder
exceeds this limit, it can't store new messages. For example, if the Deletions
folder in the Recoverable Items folder has exceeded the message count limit and
the mailbox owner attempts to permanently delete items from their mailbox, the
deletion will fail.

-EMAILADDRESSES
The EmailAddresses parameter specifies all email addresses (proxy addresses) for
the recipient, including the primary SMTP address. In on-premises Exchange
organizations, the primary SMTP address and other proxy addresses are typically
set by email address policies. However, you can use this parameter to configure
other proxy addresses for the recipient. For more information, see Email address
policies in Exchange Server.
Valid syntax for this parameter is
"Type:EmailAddress1","Type:EmailAddress2",..."Type:EmailAddressN". The optional
Type value specifies the type of email address. Examples of valid values
include:
* SMTP: The primary SMTP address. You can use this value only once in a
command.
* smtp: Other SMTP email addresses.
* X400: X.400 addresses in on-premises Exchange.
* X500: X.500 addresses in on-premises Exchange.
If you don't include a Type value for an email address, the address is assumed
to be an SMTP email address. The syntax of SMTP email addresses is validated,
but the syntax of other email address types isn't validated. Therefore, you need
to verify that any custom addresses are formatted correctly.
To specify the primary SMTP email address, you can use any of the following
methods:
* Use the Type value SMTP on the address.
* The first email address when you don't use any Type values, or when you use
multiple lowercase smtp Type values.
* Use the PrimarySmtpAddress parameter instead. You can't use the
EmailAddresses parameter and the PrimarySmtpAddress parameter in the same
command.
The PrimarySmtpAddress parameter updates the primary email address and
WindowsEmailAddress property to the same value.
To replace all existing proxy email addresses with the values you specify, use
the following syntax:
"Type:EmailAddress1","Type:EmailAddress2",..."Type:EmailAddressN".
To add or remove specify proxy addresses without affecting other existing
values, use the following syntax:
@{Add="Type:EmailAddress1","Type:EmailAddress2",...;
Remove="Type:EmailAddress3","Type:EmailAddress4",...}.

-ENABLEROOMMAILBOXACCOUNT
This parameter is functional only in on-premises Exchange.
The EnableRoomMailboxAccount parameter specifies whether to enable the disabled
user account that's associated with this room mailbox. Valid values are:
* $true: The disabled account that's associated with the room mailbox is
enabled. You also need to use the RoomMailboxPassword with this value. The
account is able to log in and access the room mailbox or other resources.
* $false: The account that's associated with the room mailbox is disabled. The
account is not able to log in and access the room mailbox or other resources.
In on-premises Exchange, this is the default value.
You need to enable the account for features like the Skype for Business Room
System or Microsoft Teams Rooms.
A room mailbox in Exchange Online is created with associated an account that has
a random, unknown password. This account is active and visible in Microsoft
Graph PowerShell and the Microsoft 365 admin center just like a regular user
account, but it consumes no licenses. To prevent this account from being able to
log in after you create the mailbox, use the AccountEnabled parameter on the
Update-MgUser cmdlet in Microsoft Graph PowerShell.

-ENDDATEFORRETENTIONHOLD
The EndDateForRetentionHold parameter specifies the end date for retention hold

the RetentionHoldEnabled parameter to the value $true.
Important: Using this parameter does not change the RetentionHoldEnabled value
to $false after the specified date. The RentionHoldEnabled will still be $true
on the mailbox after the specified date, but MRM will start processing mailbox
items as normal.
Use the short date format that's defined in the Regional Options settings on the
computer where you're running the command. For example, if the computer is
configured to use the short date format MM/dd/yyyy, enter 09/01/2018 to specify
September 1, 2018. You can enter the date only, or you can enter the date and
time of day. If you enter the date and time of day, enclose the value in

-GRANTSENDONBEHALFTO
The GrantSendOnBehalfTo parameter specifies who can send on behalf of this
mailbox. Although messages send on behalf of the mailbox clearly show the sender
in the From field (<Sender> on behalf of <Mailbox>), replies to these messages
are delivered to the mailbox, not the sender.
The sender you specify for this parameter must a mailbox, mail user or
mail-enabled security group (a mail-enabled security principal that can have
permissions assigned). You can use any value that uniquely identifies the
sender. For example:
* Name
* Alias
* Distinguished name (DN)

-IMLISTMIGRATIONCOMPLETED
This parameter is available only in on-premises Exchange.
The ImListMigrationCompleted parameter specifies whether a user's Lync or Skype
for Business contact list is stored in their mailbox.
Valid values are:
* $true: The user's Lync or Skype for Business contact list is stored in their
Exchange 2016 mailbox. This prevents you from migrating the mailbox back to
an Exchange 2010 server.
* $false: The user's Lync or Skype for Business contact list is stored on a
Lync or Skype for Business server. This doesn't prevent you from migrating
the mailbox back to an Exchange 2010 server. This is the default value.
Lync Server 2013 and Skype for Business Server 2015 support storing the user's
contact list in their Exchange 2016 mailbox. This feature is known as the
unified contact store (UCS), and it allows applications to show a consistent,
up-to-date contact list. However, Exchange 2010 doesn't support the unified
contact store. Therefore, before you migrate a user's Exchange 2016 mailbox back
to Exchange 2010, you need to move the user's Lync or Skype for Business contact
list from the unified contact store back to a Lync 2013 or Skype for Business
server. For more information, see Configuring Microsoft Lync Server 2013 to use
the unified contact store.
If you migrate an Exchange 2013 mailbox back to Exchange 2010 while the user's
Lync or Skype for Business contact list is stored in the unified contact store,
the user could permanently lose access to those contacts. After you verify the
user's Lync or Skype for Business contact list has been moved back to a Lync
2013 or Skype for Business server, you should be able to complete the mailbox
migration. If you need to migrate the mailbox despite the potential for data
loss, you can manually set the ImListMigrationCompleted parameter to $false.

-IMMUTABLEID
The ImmutableId parameter is used by GAL synchronization (GALSync) and specifies
a unique and immutable identifier in the form of an SMTP address for an Exchange
mailbox used for federated delegation when requesting Security Assertion Markup
Language (SAML) tokens. If federation is configured for this mailbox and you
don't set this parameter when you create the mailbox, Exchange creates the value
for the immutable ID based upon the mailbox's ExchangeGUID and the federated
account namespace, for example,
7a78e7c8-620e-4d85-99d3-c90d90f29699@mail.contoso.com.
You need to set the ImmutableId parameter if Active Directory Federation
Services (AD FS) is deployed to allow single sign-on into an off-premises
mailbox and AD FS is configured to use a different attribute than ExchangeGUID
for sign-on token requests. Both, Exchange and AD FS must request the same token
for the same user to ensure proper functionality for a cross-premises Exchange
deployment scenario.

-INACTIVEMAILBOX
This parameter is available only in the cloud-based service.
The InactiveMailbox switch specifies that the mailbox is an inactive mailbox.
You don't need to specify a value with this switch.
An inactive mailbox is a mailbox that's placed on Litigation Hold or In-Place
Hold before it's soft-deleted.
To find inactive mailboxes, run the command Get-Mailbox -InactiveMailboxOnly |
Format-List Name,PrimarySmtpAddress,DistinguishedName,ExchangeGuid and then use
the DistinguishedName or ExchangeGuid property values for the Identity parameter
(values guaranteed to be unique).
This switch is required to use the LitigationHoldEnabled and
LitigationHoldDuration parameters on inactive mailboxes.
You can't use this switch to modify other properties on inactive mailboxes.

-ISEXCLUDEDFROMSERVINGHIERARCHY
The IsExcludedFromServingHierarchy parameter prevents users from accessing the
public folder hierarchy on this public folder mailbox. For load-balancing
purposes, users are equally distributed across public folder mailboxes by
default. When this parameter is set on a public folder mailbox, that mailbox
isn't included in this automatic load-balancing and won't be accessed by users
to retrieve the public folder hierarchy. However, if an administrator has set
the DefaultPublicFolderMailbox property on a user mailbox to a specific public
folder mailbox, the user will still access the specified public folder mailbox
even if the IsExcludedFromServingHierarchy parameter is set for that public
folder mailbox.
You should use this parameter only during public folder migrations. Don't use
this parameter once the initial migration validation is complete.

-ISSUEWARNINGQUOTA
The IssueWarningQuota parameter specifies the warning threshold for the size of
the mailbox. If the mailbox reaches or exceeds this size, the user receives a
descriptive warning message.
A valid value is a number up to 1.999999999 terabytes (2199023254528 bytes) or
the value unlimited. When you enter a number, you can qualify it with one of the
following units:
* B (bytes)
* KB (kilobytes)
* MB (megabytes)
* GB (gigabytes)
* TB (terabytes)
Unqualified values are typically treated as bytes, but small values may be
rounded up to the nearest kilobyte.
The IssueWarningQuota value must be less than or equal to the
ProhibitSendReceiveQuota value.
In Exchange Online, the quota value is determined by the subscriptions and
licenses that administrators purchase and assign in the Microsoft 365 admin
center. You can lower the quota value, and you may be able to raise the quota,
but you can't exceed the maximum value that's allowed by the subscription or
license. In Exchange Online, you can't use this parameter on public folder
mailboxes.
In on-premises Exchange, the default value of this parameter is unlimited. When
the UseDatabaseQuotaDefaults parameter on the mailbox is set to $true (the
default value), the value of the this parameter is ignored, and the mailbox uses
the IssueWarningQuota value from the mailbox database. To use this parameter to
enforce a specific quota value for the mailbox, you need to set the
UseDatabaseQuotaDefaults parameter to the value $false.

This parameter is available only in on-premises Exchange.
The MaxBlockedSenders parameter specifies the maximum number of senders that can
be included in the blocked senders list. Blocked senders are senders that are
considered junk senders by the mailbox and are used in junk email rules. This
parameter is validated only when the junk email rules are updated using Outlook
on the web or Exchange Web Services.

-MAXRECEIVESIZE
The MaxReceiveSize parameter specifies the maximum size of a message that can be
sent to the mailbox. Messages larger than the maximum size are rejected.
When you enter a value, qualify the value with one of the following units:
* B (bytes)
* KB (kilobytes)
* MB (megabytes)
* GB (gigabytes)
Unqualified values are typically treated as bytes, but small values may be
rounded up to the nearest kilobyte.
A valid value is a number up to 1.999999 gigabytes (2147483647 bytes) or the
value unlimited.
In Exchange Online, the value is determined by the subscriptions and licenses
that administrators purchase and assign in the Microsoft 365 admin center. You
can lower the value, and you may be able to raise the value, but you can't
exceed the maximum value that's allowed by the subscription or license.
In Exchange Online, you use this parameter to configure the MaxReceiveSize value
on existing mailboxes. Use the Set-MailboxPlan cmdlet to change the
MaxReceiveSize value for all new mailboxes that you create in the future.
In on-premises Exchange, the default value unlimited indicates the maximum
receive size for the mailbox is imposed elsewhere (for example, organization,
server, or connector limits).
Base64 encoding increases the size of messages by approximately 33%, so specify
a value that's 33% larger than the actual maximum message size that you want to
enforce. For example, the value 64 MB results in a maximum message size of
approximately 48 MB.

In Exchange Online, the quota value is determined by the subscriptions and
licenses that administrators purchase and assign in the Microsoft 365 admin
center. You can lower the quota value, and you may be able to raise the quota,
but you can't exceed the maximum value that's allowed by the subscription or
license. In Exchange Online, you can't use this parameter on public folder
mailboxes.
In on-premises Exchange, the default value of this parameter is unlimited. When
the UseDatabaseQuotaDefaults parameter on the mailbox is set to the value $true
(the default value), the value of the this parameter is ignored, and the mailbox
uses the ProhibitSendQuota value from the mailbox database. To use this

-REJECTMESSAGESFROMDLMEMBERS
The RejectMessagesFromDLMembers parameter specifies who isn't allowed to send
messages to this recipient. Messages from these senders are rejected.
Valid values for this parameter are groups in your organization (distribution
groups, mail-enabled security groups, and dynamic distribution groups).
Specifying a group means all members of the group aren't allowed to send
messages to this recipient. You can use any value that uniquely identifies the
group. For example:
* Name
* Alias
* Distinguished name (DN)
* Canonical DN
* Email address
* GUID
You can enter multiple groups separated by commas. To overwrite any existing
entries, use the following syntax: Group1,Group2,...GroupN. If the values
contain spaces or otherwise require quotation marks, use the following syntax:
"Group1","Group2",..."GroupN".
To add or remove groups without affecting other existing entries, use the
following syntax: @{Add="Group1","Group2"...; Remove="Group3","Group4"...}.

-REJECTMESSAGESFROMSENDERSORMEMBERS
The RejectMessagesFromSendersOrMembers parameter specifies who isn't allowed to
send messages to this recipient. Messages from these senders are rejected.
Valid values for this parameter are individual senders and groups in your
organization. Individual senders are mailboxes, mail users, and mail contacts.
Groups are distribution groups, mail-enabled security groups, and dynamic
distribution groups. Specifying a group means all members of the group aren't
allowed to send messages to this recipient.
To specify senders for this parameter, you can use any value that uniquely
identifies the sender. For example:
* Name
* Alias
* Distinguished name (DN)
* Canonical DN
* Email address

To add or remove individual senders or groups without affecting other existing
entries, use the RejectMessagesFrom and RejectMessagesFromDLMembers parameters.
The individual senders and groups you specify for this parameter are
automatically copied to the RejectMessagesFrom and RejectMessagesFromDLMembers
properties, respectively. Therefore, you can't use the
RejectMessagesFromSendersOrMembers parameter and the RejectMessagesFrom or
RejectMessagesFromDLMembers parameters in the same command.
By default, this parameter is blank ($null), which allows this recipient to

This parameter is available only in the cloud-based service.
The RemoveDelayHoldApplied switch specifies whether to remove delay holds on
email-related data (generated by Outlook or Outlook on the web) from the
mailbox. You don't need to specify a value with this switch.
The removal of a hold from a mailbox is temporarily delayed to prevent the
accidental purge of content that's no longer affected by the hold. This
temporary delay in the removal of the hold is known as a delay hold. To see the
hold history on a mailbox, replace <MailboxIdentity> with the name, email
address, or alias of the mailbox, and run this command:
Export-MailboxDiagnosticLogs -Identity <MailboxIdentity> -ComponentName
HoldTracking.
You can use this switch with the GroupMailbox or InactiveMailbox switch to
remove delay holds from group mailboxes or inactive mailboxes. For more

-REMOVEORPHANEDHOLDS
This parameter is available only in the cloud-based service.
The RemoveOrphanedHolds parameter is used to remove the mailbox (typically, an
inactive mailbox) from In-Place Holds that no longer exist, but are still
applied to the mailbox. You identify the In-Place Hold by using its GUID value.
You can specify multiple GUID values separated by commas.
If you use the GUID value of an In-Place Hold that still exists as a value for
this parameter, the command will return an error. If that happens, you'll need
to remove the mailbox (or inactive mailbox) from the In-Place Hold.
In an Exchange hybrid deployment, In-Place Holds that are created in the
on-premises organization can be applied to cloud-based mailboxes. In this
scenario, it's possible that the hold object hasn't been synced to the
cloud-based organization, and using this parameter will remove the specified
hold from the cloud-based mailbox even though the hold may still exist. To
prevent this from happening, make sure the hold doesn't exist in the on-premises
organization before you use this parameter.

-RETAINDELETEDITEMSFOR
The RetainDeletedItemsFor parameter specifies the length of time to keep
soft-deleted items for the mailbox. Soft-deleted items are items that have been
deleted by using any of these methods:
* Deleting items from the Deleted Items folder.
* Selecting the Empty Deleted Items Folder action.
* Deleting items using Shift + Delete.
These actions move the items into the Recoverable Items\Deletions folder.
Before the deleted item retention period expires, users can recover soft-deleted
items in Outlook and Outlook on the web by using the Recover Deleted Items
feature. For more information, see Recoverable Items folder in Exchange Server.
To specify a value, enter it as a time span: dd.hh:mm:ss where dd = days, hh =
hours, mm = minutes, and ss = seconds.
The default value is 14 days (14.00:00:00). In Exchange Online, you can increase
the value to a maximum of 30 days.
In Exchange Online, you use this parameter to configure the deleted item
retention on existing mailboxes. Use the Set-MailboxPlan cmdlet to change the
RetainDeletedItemsFor value for all new mailboxes that you create in the future.
In on-premises Exchange, when the UseDatabaseQuotaDefaults parameter on the
mailbox is set to the value $true (the default value), the value of the this
parameter is ignored, and the mailbox uses the DeletedItemRetention value from
the mailbox database. To use the RetainDeletedItemsFor parameter on the mailbox,
you need to set the UseDatabaseQuotaDefaults parameter to the value $false.

-RETAINDELETEDITEMSUNTILBACKUP
This parameter is available only in on-premises Exchange.
The RetainDeletedItemsUntilBackup parameter specifies whether to keep items in
the Recoverable Items\Deletions folder of the mailbox until the next database
backup occurs. Valid values are:
* $true: Deleted items are kept until the next mailbox database backup. This
value could effectively override the DeletedItemRetention and
RecoverableItemsQuota parameter values.
* $false: This is the default value. Retention of deleted items in mailboxes is
controlled by the DeletedItemRetention and RecoverableItemsQuota parameter
values.
When the UseDatabaseRetentionDefaults parameter on the mailbox is set to the
value $true (the default value), the value of the this parameter is ignored, and
the mailbox uses the RetainDeletedItemsUntilBackup parameter value from the
mailbox database. To use the RetainDeletedItemsUntilBackup parameter on the
mailbox, you need to set the UseDatabaseRetentionDefaults parameter to the value
$false.

The RetentionHoldEnabled parameter specifies whether the mailbox is placed on
retention hold. Placing the mailbox on retention hold temporarily suspends the
processing of retention policies or managed folder mailbox policies for the
mailbox (for example, when the user is on vacation). Valid values are:
* $true: The mailbox is placed on retention hold. Retention policies and
managed folder policies are suspended for the mailbox, and purging items from
the mailbox isn't possible (even using MFCMapi).
* $false: The retention hold is removed from the mailbox. The mailbox is
subject to retention policies and managed folder policies. This is the
default value.
To set the start date for retention hold, use the StartDateForRetentionHold
parameter.

This parameter is functional only in on-premises Exchange.
Use the RoomMailboxPassword parameter to configure the password for the account
that's associated with the room mailbox when that account is enabled and able to
log in (the EnableRoomMailboxAccount parameter is set to the value $true).
To use this parameter in on-premises Exchange, you need to be a member of one of
the following role groups:
* The Organization Management role group via the Mail Recipients and User
Options roles.
* The Recipient Management role group via the Mail Recipients role.
* The Help Desk role group via the User Options role.
The Reset Password role also allows you to use this parameter, but it isn't
assigned to any role groups by default.
You can use the following methods as a value for this parameter:
* (ConvertTo-SecureString -String '<password>' -AsPlainText -Force).
* Before you run this command, store the password as a variable (for example,
$password = Read-Host "Enter password" -AsSecureString), and then use the
variable ($password) for the value.
* (Get-Credential).password to be prompted to enter the password securely when
you run this command.
To configure the password for a room mailbox account in Exchange Online, use the
PasswordProfile parameter on the Update-MgUser cmdlet in Microsoft Graph
PowerShell.

The RulesQuota parameter specifies the limit for the size of Inbox rules for the
mailbox. When you enter a value, qualify the value with one of the following:
A valid value is a number from 32 to 256 kilobytes (32768 to 262144 bytes). When
you enter a value, qualify the value with one of the following units:
* B (bytes)
* KB (kilobytes)
Unqualified values are typically treated as bytes, but small values may be
rounded up to the nearest kilobyte.
In Exchange Online, Exchange 2019, Exchange 2016, and Exchange 2013, the default
value is 256 kilobytes (262,144 bytes).
In Exchange 2010, the default value is 64 kilobytes (65,536 bytes).
The quota for Inbox rules applies only to enabled rules. There is no restriction
on the number of disabled rules a mailbox can have. However, the total size of
rules that are enabled or active can't exceed the value specified for this

-UMDTMFMAP
This parameter is available only in on-premises Exchange.
The UMDtmfMap parameter specifies the dual-tone multiple-frequency (DTMF) map
values for the recipient. This allows the recipient to be identified by using a
telephone keypad in Unified Messaging (UM) environments. Typically, these DTMF
values are automatically created and updated, but you can use this parameter to
make changes manually. This parameter uses the following syntax:
* emailAddress:<integers>
* lastNameFirstName:<integers>
* firstNameLastName:<integers>
To enter values that overwrite all existing entries, use the following syntax:
emailAddress:<integers>,lastNameFirstName:<integers>,firstNameLastName:<integers>.
If you use this syntax and you omit any of the DTMF map values, those values are
removed from the recipient. For example, if you specify only
emailAddress:<integers>, all existing lastNameFirstName and firstNameLastName
values are removed.
To add or remove values without affecting other existing entries, use the
following syntax:
@{Add="emailAddress:<integers>","lastNameFirstName:<integers>","firstNameLastName:<integers>";
Remove="emailAddress:<integers>","lastNameFirstName:<integers>","firstNameLastName:<integers>"}.
If you use this syntax, you don't need to specify all of the DTMF map values,
and you can specify multiple DTMF map values. For example, you can use
@{Add="emailAddress:<integers1>","emailAddress:<integers2>} to add two new
values for emailAddress without affecting the existing lastNameFirstName and
firstNameLastName values.

-UMGRAMMAR
This parameter is available only in on-premises Exchange.
The UMGrammar parameter specifies whether the arbitration mailbox (also called
an organization mailbox) is used for UM directory speech grammar generation for
the organization. UM directory speech grammars will be generated and used on the
Mailbox server of this arbitration mailbox. UM directory speech grammars are
used in speech-enabled directory search features, such as UM auto attendants.
You can use this parameter only on an arbitration mailbox.
Valid values are $true or $false.

-USEDATABASEQUOTADEFAULTS
The UseDatabaseQuotaDefaults parameter specifies whether applicable quotas for
the mailbox are determined by the quota values on the mailbox or the
corresponding quota values on the mailbox database (not all mailbox quotas are
configurable on the mailbox database). Valid values are:
* $true: The mailbox uses the applicable quota values that are configured on
the mailbox database. Any corresponding quotas that are configured on the
mailbox are ignored. In on-premises Exchange, this is the default value.
* $false: The mailbox uses its own values for the applicable quotas. Any
corresponding quotas that are configured on the mailbox database are ignored.
In Exchange Online, this is the default value.
The following quotas are affected by this parameter:
* CalendarLoggingQuota
* IssueWarningQuota
* ProhibitSendQuota
* ProhibitSendReceiveQuota
* RecoverableItemsQuota
* RecoverableItemsWarningQuota

-USEDATABASERETENTIONDEFAULTS
This parameter is functional only in on-premises Exchange.
The UseDatabaseRetentionDefaults parameter specifies whether the retention
settings for items in the Recoverable Items folder in the mailbox are determined
by the settings on the mailbox or the corresponding settings on the mailbox
database. Valid values are:
* $true: The mailbox uses the applicable retention settings that are configured
on the mailbox database. Any corresponding settings that are configured on
the mailbox are ignored. This is the default value.
* $false: The mailbox uses its own values for the applicable retention
settings. Any corresponding settings that are configured on the mailbox
database are ignored.
The following retention settings are affected by this parameter:
* DeletedItemRetention
* RetainDeletedItemsUntilBackup
Note: If you set the RetainDeletedItemsUntilBackup parameter on the mailbox
database to the value $true when the value of the UseDatabaseRetentionDefaults
parameter on a mailbox is also $true (the default value), the value of the
UseDatabaseRetentionDefaults property in the output of the Get-Mailbox cmdlet
will erroneously appear as False. To verify the value of the
UseDatabaseRetentionDefaults property on the mailbox, do the following steps in
the Exchange Management Shell:
* Run the following command: Import-Module ActiveDirectory.
* Replace <Alias> with the Alias value of the mailbox, and run the following
command: Get-ADUser <Alias> -Properties mDBUseDefaults | Format-List
mDBUseDefaults.

-WINDOWSEMAILADDRESS
The WindowsEmailAddress parameter specifies the Windows email address for this
recipient. This is a common Active Directory attribute that's present in all
environments, including environments without Exchange. Using the
WindowsEmailAddress parameter on a recipient has one of the following results:
* In environments where the recipient is subject to email address policies (the
EmailAddressPolicyEnabled property is set to the value True for the
recipient), the WindowsEmailAddress parameter has no effect on the
WindowsEmailAddress property or the primary email address value.
* In environments where the recipient isn't subject to email address policies
(the EmailAddressPolicyEnabled property is set to the value False for the
recipient), the WindowsEmailAddress parameter updates the WindowsEmailAddress
property and the primary email address to the same value.
The WindowsEmailAddress property is visible for the recipient in Active
Directory Users and Computers in the E-mail attribute. The attribute common name
is E-mail-Addresses, and the Ldap-Display-Name is mail. If you modify this
attribute in Active Directory, the recipient's primary email address is not
updated to the same value.
