Hi, I have 2 domains, Domain A (Account Forest) and Domain B (Exchange Resource Forest), both are in Trust (2 way) at Forest level. I have created Linked Mailboxes for Domain A users, keeping their AD Account disabled in Domain B. I'm able to resolve the Linked Mailboxes but not able to log into them. When I try logging, the User Name and pwd prompt keep popping up. What am I missing here? Please help.

I would start with the basics. Is the trust relationship working correctly? Jim McBee - Blog - http://mostlyexchange.blogspot.com

Have you set the account up properly - http://technet.microsoft.com/en-us/library/bb123524.aspx Dont know what verssion youre using. Sukh

Yes Jim, I have run Validate under Trust tab, its says its active.Raj-

I have run Incoming also, trust works fine. Is there any other way we check this?Raj-
