Digitally sign a message
Digitally signing a message applies your public-key certificate to the message.
This proves to the recipient that the message is from you and not from an
impostor, and that the message has not been altered.

Note: S/MIME encryption and digital signatures for Windows Mobile®-based devices are
available only with Exchange Server 2003 Service Pack 2 or later versions that support
S/MIME. If you are not using one of these products, or have not yet synchronized, these
options are unavailable.
