DOWNLOAD AN ATTACHMENT
In an open message with an attachment to download, press the
attachment. The attachment is downloaded the next time you
synchronize or connect to your e-mail server and send and receive
e-mail.
If there are multiple attachments in the message, all
attachments are downloaded.
ENCRYPT A MESSAGE
Encrypting a message protects the privacy of the message by
converting it from plain, readable text into cipher (scrambled) text. Only
the recipient who has the private key that matches the public key you
used to encrypt the message can decipher the message.
You can encrypt a message without a certificate, however, to read an
encrypted message you need a valid certificate for decrypting e-mail
messages.

Accounts Outlook e-mail.

S/MIME encryption and digital signatures for Windows Mobile-
