I am having a problem with a user on my network. I have recently upgaded office 2003 to 2007. Since the upgrade I have been having problems with this users outlook email. I simply cannot sent and recieve emails from his pc. I setup his email the same as all other users, they are working fine. I can even setup his email on another workstation with the same exact settings and it works. The event logs don't suggest any problems at all. I have also un/reinstalled office on his pc. Nothing. I'm at my wits end. He is running windows XP-64bit. Most of his apps are 32bit. Any suggestions?
