4.5 Setting Up 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 your messages as well as encrypt them.
Using authorization keys and certificates, S/MIME allows you to digitally
sign your e-mail messages to prove your identity to the recipients.
Authorization keys are also used when encrypting messages to improve
privacy and prevent undue tampering or hacking of your messages. You
can encrypt a message with or without a certificate. However, to read an
encrypted message, you need a valid certificate to decrypt it.
Note
S/MIME encryption and digital signatures for Windows Mobile-based devices
are available only with Exchange Server 2003 Service Pack 2 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.
Digitally sign and encrypt all messages
ActiveSync allows you to set up S/MIME e-mail encryption and signing.
You must obtain a valid certificate to sign and encrypt e-mail messages
successfully.
