I have inherited the wonderful job of administering an Exchange server with 1100 mailboxes.
In the past this server managed mail from 3 domains, but now things have changed so we now have only 1 domain left !
under recipient policy -> default policy -> properties i have removed all unwanted domains.
But my users still get mails from the old domains. And if i look in the ad i can see that users still have their old email under the tab e-mail address. If i remove this old email manually on the user, it bounces. But i can´t manually delete for 1100 users...
What have i done wrong, or have i missed something?
