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® powered devices are available only with Exchange 

Server 00 SP 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.

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.
