Error
ExchangeStoreDB 225
Database recovery
At 'date and Time' the copy of database 'Mailbox Database Random ' on this server was unexpectedly dismounted. The error returned by failover was "There is only one copy of this mailbox database (Mailbox Database Random). Automatic recovery is not available.". For more specific information about the failures, consult the event log on the server for other "ExchangeStoreDb" events.
Resolution : Issue happens only when Exchange 2007 is installed along with Exchange 2013, Databases on Exchange 2013 automatically dismount
Install "Interim update" provided from Microsoft or wait for next CU/SP.
To receive IU, you need to open a case with Microsoft.

=============
The problem occurs when a user whose mailbox is located in Exchange Server 2007 tries to access a delegated mailbox that is located on a server that is running Exchange Server 2013 CU6.
When the updated server that is running Exchange Server 2013 tries to authenticate the user, it uses a mechanism that is not understood by Exchange Server 2007. This causes the Exchange Server 2013 Store process to crash and fail over the database to a different server. Co-existence with Microsoft Exchange Server 2010 is not affected by this problem.

We are having the same error. Where did you find the interim update?
ReplyDeleteYou need to contact Microsoft and open a case with them
ReplyDeleteDid that on Sunday and got the hot fix installed. Initially the Microsoft engineer was saying this hot fix only applies to environments with DAG configured. But I showed him the event log and the behaviour of Exchange on migrations and he agreed to install it. Now Exchange works without any issues.
ReplyDeleteIn my case, i gave reference to KB https://support.microsoft.com/kb/2997209 and immediately received IU and resolved the issue
ReplyDeletehttps://support.microsoft.com/kb/2986485 : CU is available. I have install and after a rebbot, all is right!
ReplyDeleteThanks Frenatik
