Exchange server 2003. I returned to the office and when Entourage asked if I wanted to turn OOF off I selected yes. Checking Outlook, and Exchange web access, everything shows that I am in the office. Exchange however is still sending my OOF message. I have had to disable OOF at the server to get it to stop.
Any ideas?

sounds like outlook is not communicating with the server properly, have you tried restarting outlook? Or the server itself?
