I have a 3 branch company and therefore 3 domains. The main branch contains a Exchange 5.5 server (with SP4) as well as a proxy server. I have all the proper trusts set-up, but some reason, only the people in the main branch can connect to OWA. When we log in to OWA, we put user name only on the first screen, then when password box comes up, I put domain name/username. Can anyone tell me what my probably problem is?
