Email Encryption Outlook Add-in adds an Encrypt button to the Outlook Compose window toolbar. The Encrypt button marks your message for encryption by inserting a special tag into the email header. The Gateway detects this tag and encrypts the message if necessary.

Note: An encryption rule must be defined that scans email headers for this information and triggers the encryption

In order to use the Email Encryption Outlook add-in, you need to install Email Encryption Outlook plugin on the machine you want to send encrypted messages from.
