    There would need to be a trust setup between the 2 domains in "Active Directory Domains and Trusts" on the domain controller.

    What if the exchange servers are in the same Domain but different Forest?  For instance both units login into 123 however our Exchange Servers are named TwoC and ThreeC.  I can't see the users nor can they see me.  However, if I have an account on both Two and ThreeC could I setup Outlook thru the ThreeCs proxy server and my mailbox on that server?
