I'm running windows 2000 and I have microsoft office 2003 standard edition. I set up microsoft exchange server 2003 at our office and set up all of the client stations will outlook 2003 and I set all of them up with a microsoft exchange account. All of the machines work except for one of the machines running windows 2000. It will recieve email just fine however when I send and recieve it doesn't kick them out of the outbox nor send them. And I'm stumped at this point, so if anyone has any ideas or suggestions please let me know.
