Re: New Exchange Server. ActiveSync errors.
Looking at the queues.
hub version 14 tab has 395 queued and has a last error of
451 4.4.0 Primary target IP address responded with “451 5.7.3 Cannot achieve Exchange Server authentication.” Attempted failover to alternative host, but that did not succeed. Either there are no alternate hosts, or delivery failed to all alternate hosts.
Unreachable Domain tab has 103 queued and has a last error of
“There is no route to the mailbox database”
All the 103 queued have this error.
I believe we should enable Integrated auth (Authentication tab) on the Default Receive connector on Exchange 2010 server. Restart MS Exchange Transport service and then see if the queue is clearing up or not.
