Scenario: There are two domains, A and B

Exchange Server resides in domain A. User resides in domain B

For security reasons Domain A and B cannot have a trust setup.

Question: Is it possible for a user on domain B to connect/authenticate to a mailbox on an Exchange server in domain A? If so how?

Your thoughts and comments would be most welcome..

Only if they have a logon in Domain A that they can authenticate against.
