I am in the middle of a transition from Exchange 20007 to Exchange 2007.
I have moved across a couple of mailboxes to test on 2007 server
Currently there are 2000 messages in my message queues and I cannot receive incoming or outgoing email
The error in the event log is:
Event ID 1009
The microsoft exchange mail submission service is currently unable to cintact any hub transport servers in the local active directory site. The servers may be too busy to accept new connections at this time
