Have you looked at this KB article? FIX: Error message when you use the New-MoveRequest task to move a mailbox from Exchange 2007 to Exchange 2010: "Error: MapiExceptionNetworkError: Unable to make connection to the server. (hr=0x80040115, ec=-2147221227)" It may be applicable to your setup. If not then I'd be checking on name resolution. Is the 2007 server able to resolve the mailbox servers by both netbios and fqdn?
