8.4 E-mail Security
Windows Mobile protects your Outlook e-mails through Secure/Multipurpose Internet Mail Extension
(S/MIME), which allows you to digitally sign and encrypt your messages.
Digitally signing a message applies your certificate with the authorization key to the message. This proves to
the recipient that the message is from you and not from an imposter or a hacker, and that the message has
not been altered.
Encryption protects the privacy of your message by converting it from plain, readable text into cipher
(scrambled) text. Only the recipient who has the authorization key can decipher the message.
Requirement
Note You can encrypt a message with or without a certificate. However, to read an encrypted message, you need a valid
certificate to decrypt it.
To individually sign and encrypt a new message
1.
In the message list, tap Menu > Go To > Outlook E-mail.
2.
Tap New.
3.
Tap Menu > Message Options.
4.
Select the Encrypt message and Sign message check boxes, and tap OK.
To verify the digital signature on a signed message you receive
1.

2.
At the top of the message, tap View Signature Status.

S/MIME encryption and digital signatures for Windows Mobile-based devices are available only with
Exchange Server 2003 SP2 or a later version that supports S/MIME. If your company is not using
one of these products, or you have not completed your first synchronization with the Exchange
Server, these options are unavailable.
