Here is the scenario and what has been done:
SBS 2003 with Exchange SP2
Outlook 2003 running on XP SP3
Had to rebuild a new server from scratch
I am able to ping and resolve their FQDN
Outlook web access works https://FQDN/exchange
RWW works: https://FQDN/exchange
Certificate is installed and valid
I removed the old profile from outlook 2003 and started from scratch. Disabled cached mode, using RPC over HTTP with SSL. When I try to connect it keeps asking me for the password, over and over and over. I have the correct username and password. I have tried:
None work. However, I setup a dummy account and setup the mail box there and it works like a charm! However, even when I put the username and password in for the account I am having problems with, I don't see any attempt to authenticate in the Security logs in Event Viewer...none!
Where should I go from here? I have reproduced this same problem on 3 different computers on 3 different WAN connections. The issue doesn't seem to be local for some reason. Any help is appreciated.
