I have forest trust established between forest A and B. Exchange is installed in forest A. My query is that my users in forest B will login to their computers joined to forest B with their forest B credentials. They have mailbox created in forest A and login to outlook using forest A credentials. Will outlook connect internally or externally or not connect at all.
I know this is a little twisted and I also know about linked mailbox but I want to know how outlook would work in situation described by me above.
