If I understand, Exchange 2010 uses the log shipping between 2 database to keep them synchronized.
The Hub-T server has a role as "Dumpster".
Now, let say the Mailbox server1 has the active copy of the DB and when in the process of synching with MB2 , it has failed and the MB2 became the Active. how does the MB2 get the missing emails from MB1 seeing that the synching was not complete.?
