I need to move an Exchange 5.5 server to a different NT domain, which has a 2-way trust with the existing domain. I moved the server into the new domain, without touching Exchange permissions or service accounts. The Exchange services all started OK, & X400 mail flowed fine. However, mail in the private IS stuck in the queue & would not deliver. Also, although clients could access their mailboxes, they could not access any attachments. I moved the server back into the original domain, & now everything’s OK again. Any ideas?
