We have two domains at the college. One of the domain services the teachers and staff (A) and the other domain services the students (B). With the teachers and staff we are using exchange 2000 server and OWA works great. Recently we installed Exchange 2003 server on Windows 2003 and I am having difficulties trying to get OWA running for the student environment. I recieve a page cannot be displayed after authenticating in many ways. ( ie. student\username or username@studentdomain or just username and password. I have looked up Microsoft articles and they have been unsuccessfull as well. Is there any special permissions or settings in IIS that I need or have missed.
