Send As and Send on Behalf

To send an email either as an email address or on behalf of that email address, the instructions will be the same. However, after you have sent the message, the from section that the receiver of the email sees will be different. It will say that it is from the address itself or it is from your name on behalf of the emaill address. This is based on the permissions you have for the mailbox.
