I have recently transferred to a new company and have gone through the user setup for AD and Exchange. I have a username of tcarter. Everything setup without error. When I went to sign in to Outlook 2010 for the first time, it setup a mailbox of tcarter2, instead of tcarter. I didn't notice it as I was pretty "click happy" as I've done this setup a million times before.
I later find out that my emails are going out as tcarter2. I go to email myself from my gmail account and find that it is going to another end user, acarter. After looking through his Exchange settings, I find that he has a second alias set for tcarter. I remove that account from his and rebuild mine. He no longer has tcarter anywhere on his mailbox setup. Yet, he is still getting my emails.
Weird thing is, when you now send an internal email to tcarter, it comes to me. But when you send an external email to tcarter, it still goes to his account? Any ideas?
