Using Outlook with Exchange Server 163
Notes • Your device must be set up with a data connection.
• You can search on the following information as long as that information is
included in your organization’s Company Directory: First name, Last name,
E-mail name, Display name, E-mail address, or Office location.
10.5 E-mail Security
Windows Mobile on your device 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 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
you are not using one of these products, or have not yet
synchronized, these options are unavailable.
