We are currently using Outlook 2000 with Exchange 5.5. She uses to logon without any problem until I upgrade to Outlook 2003 it was working fine and suddenly it stops. I removed 2003 version and roll back to Outlook 2000 still any luck. I had a previous case but when I rolled it back its working fine until now. However this particular user cannot get access at all (2000 and 2003) I dont want her to loose her previous e mail. Please Help
