We have a trusted domain between a NT4.0 domain and a W2K domain. The Exchange2000 servers are on the W2K side. I reside on the NT4.0 domain. The problem is this.... I can schedule a meeting and reserve a room as a resource just fine but if I need to modify the meeting, like change the time, I get an error about not having permissions. I have full rights to the room. If I log into the W2K domain, it works fine. Any ideas?
