Hello,
We have a multi domain parent child AD domain infrastructure and now we upgraded our exchange from Exchange 2007 to Exchange 2013. Since last few days, we see the below error on the mailbox server event viewer.
--------------------------------------------------------------------------------------------------------------------------------------
EVENT ID : 1121
The Microsoft Exchange Mailbox Replication service was unable to process a request due to an unexpected error.
Request GUID: '93a7d1ca-68a1-4cd9-9edb-a4ce2f7bb4cd'
Database GUID: '83d028ec-439d-4904-a0e4-1d3bc0f58809'
Error: An Active Directory Constraint Violation error occurred on <domain controller FQDN>. Additional information: The name reference is invalid.
This may be caused by replication latency between Active Directory domain controllers.
Active directory response: 000020B5: AtrErr: DSID-0315286E, #1:

Our Exchange setup is in parent domain, but we keep on getting this error for various domain controllers in each child domain in the same site. We then configured one of the parent domain domain controller on Exchange. Still we are getting this error for the configured parent domain DC.
Verified the AD replication and there is no latency or pending stuffs.
Any support to resolve this issue will be highly appreciated. Thank you in advance.
Regards,
Jnana R Dash
