I hope someone can remind me how to do something I've already done! I have multiple domains going through my Exchange 2007 server and am now adding another. On some of the users of the other domains, I've configured it such that the actual acount is email@example.com but, if you mail in to firstname.lastname@example.org, it hits the mailbox. The reason for this is that the old addresses were in the convention first name only. We want to change to firstname.surname but obviously still need to receive mail on firstname@.
Looking through all my notes and the settings, I can't remember how I did this. Can anyone help?
