I came into the office a week ago and outlook has refused to connect ever since, it just says "Disconnected" in the bottom right-hand corner. I've tried restarting it, rebooting Windows etc.
I'm the only one if our office who is having this problem, so it's not a general problem with the server.
Things I've tried
Pinging the server via IP address and host name, both work fine
Connecting via OWA, this works using the same machine name
Connecting to Exchange via HTTP ("Outlook Anywhere") doesn't work
None of the suggestions in this question helped, http://serverfault.com/questions/21755/can-ping-exchange-server-cant-connect-outlook-to-it
Disabling Windows firewall on my laptop also has no effect.
There are no items in the event viewer that indicate that anything it up. Also no permissions have changed on the server since when it worked.
Update: I've just tried logging onto a completely different PC, using my domain controller user-name/password. When I setup outlook on there it also fails, so the problem isn't specific to 1 pc/outlook it's something about my particular user name, but not when using OWA?
What else can I do to diagnose this, any suggestions?
