Email addresses associated with an AD user are not email addresses where mail will be sent to, it is an address that incoming mail will be matched against for delivery to the associated mailbox. If you had an smtp email address of [log in to unmask] associated with your user account and a message somehow managed to arrive at your mail server for that address, then it would end up in your exchange mailbox. Setting it as the primary address only means that outgoing messages sent from that user will have that address as the originator. So if you set the above address as primary on your account, when people respond to your message it would go to [log in to unmask] and end up at microsoft's email servers! So if your internal users send messages and her @msu.edu is under her AD account at all, then the message will get delivered to that mailbox even though your mail server isn't the one handling mail for @msu.edu addresses. Delete that smtp address from her AD account and all should be good in the world. -Jeff -----Original Message----- From: MSU Network Administrators Group [mailto:[log in to unmask]] On Behalf Of Al Puzzuoli Sent: Tuesday, December 11, 2007 1:52 PM To: [log in to unmask] Subject: [MSUNAG] Email being sent to Exchange account instead of external SMTP address? Hi all, We're running a relatively typical campus setup wherein employees of our department have an rcpd.msu.edu exchange account. They set the forward on their mail.msu.edu account to pass all messages along to their rcpd.msu.edu address. Recently, one of our employees left the department. Her box on our exchange server is still active for the time being, until she can migrate all her email activity back to her msu.edu account. The problem is that if people from within our office attempt to send mail to her at her msu.edu account, the server instead routes the message to her exchange mailbox. What do I need to do to resolve this? Her msu.edu SMTP address is already set as her primary.
