The Outlook add-in can be configured to route secure messages to the DataMotion secure mailbox in three (3) different ways:
Client-Side Encrypting: In this version of the add-in the message is sent as an encrypted payload to the DataMotion secure mailbox for processing. An additional feature of the add-in is that it downloads an unencrypted version of the message from your secure email inbox directly to your Outlook inbox. This version of the Outlook add-in does not require the DataMotion secure content filter.
Server-Side Encrypting: This version of the add-in redirects a secure message over an encrypted channel to the DataMotion secure mailbox. This version of the add-in requires the DataMotion secure content filter to process and redirect the message.
Subject Line Tagging: If your policy is not to modify message headers for secure messages, then the tagging option is also available. With this option, a tag is added to the subject line of a message which can be scanned by the content filter and routed securely to the DataMotion secure mailbox. When the content filter recognizes the tag in a subject line, it strips it out before the message is forwarded to the DataMotion secure mailbox.
Note: In order to implement the tagging option, ALL of your messages will need to be routed through the DataMotion secure email content filter.
