Event 1013, MSExchange Mailbox Replication

Event 1013, MSExchange Mailbox Replication
In my Exchange 2016 CU8 environment started noticing this Event every 20+ hours

The Microsoft Exchange Mailbox Replication service was unable to synchronize Active Directory data with the request.
DB:d8383c31-6233-44b4-8ebd-4f0361bddd78
 RequestType:Sync
 RequestGuid:
 Failure:
Cannot find Template Tenant.

Did you try to restart mrs service? Also, did your AD undergo chagrs recently such as domains removed? The issue probably requires troubleshooting efforts on the AD part.

Hi,

Normally this kind of events you are experiencing, it is after one database was removed from the exchange environment.

You have a DAG or databases do not belong to different nodes?

This environment is a stand-alone server Exchange 2016, no DAG.

No changes in AD

I started seeing this after upgrading to CU8

Thanks

Hi,

Have you tried to restart Microsoft Exchange Mailbox Replication service  as Michelangelo told you?

After restarting, you continue to have the same message?

Hi,

Check if you have any move request.

Get-MoveRequest

Remove all the move request. Verify even if you have any batch

Hi all,

we have this error on multiple systems of different customers.
The event 1013 (MSExchange Mailbox Replication) starts after the installation of Exchange 2016 CU7 and still persist in CU8.

As Microsoft said, it is a "known issue" and will be fixed in future CU.

The event is showing once per day for every active database on the server. So if you have a DAG with (let's say) 4 databases, activation preference for 2 databases per server. Then every server will have 2 entries in the event log per day, because every server has 2 databases as active.

You can follow the thread on Microsoft TechNet Social about this issue:
