Hi All,
We have 5 brand new Exchange 2013 CU5 Servers. Two CAS servers, an Edge Server, and two Mailbox servers in DAG. (All of them are virtual by the way, on Hyper-v 2012 R2).
All of the mailbox databases are on both mailbox servers (of course), and some of them are active on MBX1, and the others on MBX2.
It happened twice in 2 weeks thatthe Push service wasstoppedworking. None of us received any mails on our phone (iOS and Android) or OSX -without manual refresh. Exchange Connectivity Analizer could not find any errors.
Then I have found a strange "resolution": after I made the mailbox database (where our mailboxes reside)active on the other server, Push started to work suddenly! (It worked even after I reactivated it on the original server!)
It's really annoying, because there was no error message, no event log entry, so we do not know if something goes wrong.
Did anyoneexperiencedsomething similar?
Thank you!
Adam Toth
P.S.: CU6 is not installed, but this issue is not in the list of the resolved ones.
