I am running exchange 2000 on my windows 2000 network. I have one user that cannot access the OWA over the internet. When you try to access it you get an http authorization error. I can log onto the network using his account...I can open an outlook client with his account...it is only over OWA does the problem happen. I even tried deleting his user account...his mailbox...and purging his mailbox from exchange. I then recreated all of it and restored his messages from .pst. I am still getting the same error. The exact error displayed by OWA is http/1.1 401 Unauthorized. Have any of you ever seen this? This is only happening with one out of 190 users!! Very frustrating.
