7.5 E-mail Security

Windows Mobile on your phone protects your Outlook e-mails through Secure/Multipurpose Internet Mail
Extension (S/MIME), which allows you to digitally sign and encrypt your messages.
Requirement
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.
To individually sign and encrypt a new message
1. Click Start > Messaging > Outlook E-mail.
2. Click Menu > New to create a new message.
3. Click Menu > Message Options.
4. From the Security list, select whether to encrypt only, sign the message only, or do both.
5. Click Done.
To verify the digital signature on a signed message you receive
1. Open the Outlook e-mail message that has been digitally signed.
2. At the top of the message, click View signature status.
3. Click Menu > Check Certificate.
S/MIME encryption and digital signatures for Windows Mobile-based phones 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.
