I have an interesting issue involving Exchange / Outlook 2003. I created a new user account in AD along with a new mailbox for that user. The user can log into his mailbox fine with Outlook 2003. The user is not receiving / sending or view messages sent to him. I have sent a couple messages to him and he never receives them. Also I send message to my work email using his outlook and I never receive them. Their are items in his mailbox when I check the mailbox store. He has no messages in display view when he is in outlook even though he should have messages sent to him. Internal users sent his messages and he never received them. Any suggestions?
