Using the Outlook add-in

To use the Outlook add-in, choose to create, reply or forward a message in the normal way and simply select the required alias from the send as list at the bottom of the compose window:

The chosen alias remains the same throughout the entire email conversation (unless you choose to change it later in the conversation) but any replies will still be directed to your primary mailbox.

If preferred (or if you are sending email messages from a mobile device), you can specify an alternative alias using a trigger option in the subject line.
