Digitally sign and encrypt all messages
With ActiveSync you can set up S/MIME e-mail encryption and signing. You should
obtain a valid certificate to sign and encrypt e-mail messages successfully.
1. Tap Start > Programs > ActiveSync.
2. Tap Menu > Options.
3. Select the E-mail information type, and tap Settings. Tap Advanced on the
E-mail Sync Options screen.
4. Do one or both of the following:
• Select the Sign all outgoing e-mail messages check box to sign all your
outgoing e-mail messages. By doing this, recipients can be certain that the
messages were sent by you and have not been altered in any way.
• Select the Encrypt all outgoing e-mail messages check box to encrypt all
your outgoing e-mail messages. By doing this, the contents of your messages
are protected from being viewed by anyone besides the intended recipients.
5. Tap Choose Certificate to select a certificate for signing or encrypting outgoing
e-mail messages. You can select certificates to sign or encrypt e-mail messages
individually if you do not choose to sign or encrypt all outgoing e-mail. Refer to
“Individually sign and encrypt a message” in Chapter 6.1 to get information
about signing and encrypting individual messages.
