What is the American Express Encrypted Email tool?

The American Express Encrypted Email tool provides a secure mechanism for email
communication between internal American Express email users and external
Internet business email users. The tool allows encryption and decryption of
email messages and attached files in the Internet email channel.


 


What makes the Encrypted Email tool secure?

Email messages sent from American Express through this tool are encrypted with
strong encryption and remain encrypted while stored in the recipient’s email
inbox. Decryption of the messages does not occur unless the recipient is
authenticated using their unique password. Presentation of the decrypted message
to the recipient’s browser occurs through an SSL Encrypted web session. Replies
sent back to American Express through the web-based tool are also encrypted
using SSL Encryption and are secured within the American Express internal
network and email environment.


 


How do I reply securely to an encrypted email from American Express?

The web page used to present the decrypted email will include ‘Reply’ and ‘Reply
To All’ buttons. Click on the appropriate button to compose and send a secure
reply to the American Express recipient(s). You may attach files to the new
reply message; however, files attached to the original message will not be
included in the reply message.


 


HOW SECURE ARE SECURE MESSAGES?

The secure email is encrypted with the equivalent of a 1024-bit key. It uses the
breakthrough Identity-Based Encryption to ensure the privacy of your personal
data without compromising ease of use. Each message is also signed by the sender
to ensure authenticity of the sender and data integrity of the message. In
addition, all decrypted email messages are viewed through your web browser using
an SSL/TLS connection.


 


How do I save a copy of the secure email reply that I send to American Express?

If you would like to have a copy of the encrypted reply in your email inbox, you
may select the Copy Me option prior to sending the secure reply. When you click
on the Copy Me option, the option will change to “Remove Me” which can be used
if you decide you do not want a copy of the encrypted email in your email inbox.


 


Using the American Express Encrypted Email Tool

Can I read my email when I’m not connected to the Internet?

For this current implementation of the new American Express Encrypted Email
tool, the ability to decrypt and view your emails offline will not be available.
The tool requires that you log in each time you access the system to read or
reply to encrypted emails and the secure session will timeout after a short
amount of time for security purposes. An offline capability may be made
available in the future.

How can I read the encrypted emails on my Blackberry or other mobile device?

Some mobile or Blackberry devices may not support reading attachments or
clicking on the Read Message button in the encrypted html attachment. If you
have trouble viewing the encrypted email on your mobile device, forward the
email to SecureMailProxy@aexp.com. This email address will be included on each
encrypted email for ease of use. Forwarding the encrypted email to that email
address will result in the tool generating a new email with a web link to
display the tool login page and decrypt the email content from your mobile
device. This link will expire after three (3) days. If you want to read the
encrypted email again from your mobile device after the link has expired, you
may forward the message again to the above email address and receive a new link.
If you do not receive the email with the link, please check your mobile email
settings to ensure the From address is set correctly. The link will be sent to
the From address you have specified in your email settings.

Am I able to reply securely using my Blackberry or other mobile device?

Yes, the “Reply” and “Reply to all” functionality should work from your mobile
device although some devices may not support the rich text editing capability
that is supported in a standard browser. If you are unable to enter text in the
email reply body, select the “Plain Text” option to the right of the reply
subject line.

Please ensure your Blackberry device is configured to use the Blackberry browser
when reading and replying to Encrypted Email messages. To verify the setting, go
to Menu, Options, Browser Configuration, and set the value for Browser
Identification to Blackberry. Save the configuration change and re-open the
browser to confirm the encrypted email pages are displayed correctly.

Am I able to add recipients to the email reply?

Yes, you may add recipients to the secure email reply. The tool does not
currently support an address book lookup of the American Express email address
so please ensure you have the correct email address for the American Express
recipient(s) when entering the recipient address.

Am I able to forward the encrypted email?

Yes, you have the option to securely forward the email from within the Encrypted
Email tool. If you forward the encrypted form of the email from your email
client inbox, the recipient will not be able to read the email as it was not
encrypted for them. When you forward the email from within the tool you must
include a valid American Express recipient address on the forwarded message. The
tool does not currently support an address book lookup of the American Express
email address so please ensure you have the correct email address for the
American Express recipient(s) when entering the recipient address.

Am I able to login to the Encrypted Email tool and compose a new email to
another American Express recipient or someone outside of American Express?

Yes, you may login to the Encrypted Email tool and compose a message to an
American Express recipient. Login using the webpage address in the user guide
provided to you by your American Express contact. The tool does not currently
support an address book lookup of the American Express email address so please
ensure you have the correct email address for the American Express recipient(s)
when entering the recipient address.

If I deleted an encrypted email message in my email inbox, am I able to get it
back?

The ability to recover deleted emails from your email inbox is dependent on your
email client. Please contact your technical support to determine if that is
supported. Another option may be to contact the American Express sender of the
original email and request that they resend the encrypted email.

How do I register other email addresses I use or if I change my email address?

If you change your email address or would like to receive encrypted emails from
American Express to another email address, call your American Express contact
and request that future encrypted emails be sent to the new email address. You
will be prompted to complete the registration process in the encrypted email
tool for each new email address used to send you encrypted email using this
tool.

Technical Questions

Where can I get help if I have questions or problems using the tool?

The encrypted email tool has online help information that can be used at any
point by clicking on the Help link. If you need additional assistance, please
call or send an email with your question to your American Express contact who
will engage the appropriate American Express technical resources to answer your
question or solve any problems with the tool.

What if I don’t receive the registration verification email?

If you do not receive the verification email within minutes after registering on
the Encrypted Email website, check your junk or spam email folder or contact
your company’s technology help desk. Your company’s email server may be
identifying the verification email as spam and blocking delivery to your inbox.
Most email servers allow for the sender address to be added to a “whitelist” to
allow delivery. The sender address used by American Express for the verification
emails is secure.email@aexp.com.

Does the tool require me to install software on my computer?

A standard Internet browser is the only software required to read and reply to
the encrypted emails using this tool. Browsers will need to support cookies and
allow access to secure sites (HTTPs). Current versions of Internet Explorer,
Firefox, and Safari are officially tested for compatibility but other web
browsers should work as well as long as they meet the above requirements.

Why can’t I read the encrypted email by clicking on the link that I used before
to access it?

The link you used previously was a one-time link provided as part of the
registration verification process. To read the encrypted email, open the HTML
attachment in the original encrypted email in your inbox.

Is there a way to change my password, reset a forgotten password, or unlock my
account after entering a wrong password multiple times?

Yes, the Encrypted Email login page includes a link to reset your password. You
may reset your password in one of two methods. The first involves responding
correctly to a password recovery question that you selected when registering in
the Encrypted Email tool. The second method involves requesting the system to
send an email with a one-time password reset link. When resetting your password,
the new password may not be the same as the four previous passwords used for the
system and a password may only be reset once in a 24 hour period. For added
security, the system will require you to change your password every 90 days.

What are the password requirements for the Encrypted Email tool?

The Encrypted Email tool requires that passwords are a minimum of 7 characters
and include at least one number as part of the selected password. In addition,
accounts will require a password reset (using the method described previously)
if an invalid password has been entered three or more times.

Why don’t the graphic images display when I open the encrypted email in my email
inbox?

Your email client settings may be configured to not render images for security
reasons. Depending on your email client and company policies, this setting may
be overridden for the specific email message or for all messages received from
the American Express email domain. Please contact your company technical support
for instructions to allow this function.

Why doesn’t the “Read Message” button work when the encrypted email is previewed
in my Web Mail client?

Some Web Mail clients render HTML attachments in preview mode with some of the
functionality disabled for security reasons. It is necessary to manually open
the HTML attachment using the method you would normally use for opening
attachments in your Web Mail client.

What is my personal security image and can I change the image to another picture
I prefer?

The personal security image is designed to protect against identify theft. A
personalized image is assigned to your email address the first time someone from
American Express sends you an encrypted email using this tool and it cannot be
changed. When you receive an encrypted email, you should see your personalized
image in the lower left-hand corner of the email. You should also see the image
when you open the message_zdm.html attachment. Every time you receive an
encrypted email from American Express, make sure you see your personalized
image. If your image does not appear, or if you ever see an image that reads
"Invalid Image", do not open the attachment or click on any links. Contact the
American Express sender via phone to confirm if they sent the email.

If my company has the ability to support Transport Layer Security (TLS) for
gateway to gateway email encryption between American Express and my company, is
that an option that can be implemented for use instead of the Encrypted Email
tool?

Yes, we strongly encourage the use of TLS for those external companies that
support TLS. Please engage your contact at American Express to initiate the TLS
setup process.
