Error: Mailbox Changes Failed to replicate . Database doesn’t satisfy the constraint second copy because commit time isn’t guaranteed by replication time.
- Verified NTP is fine,
- Time zones are fine.
- Verified all DAG members showing same time.
- They are in Same VLAN in same site. (In my Case its a three node DAG , 2 on primary , 1 on Second Site.)
- Database Replication seems to be healthy.
- Replication link seems to be healthy.
Even Smaller Mailboxes tend to fail with same error.
To workaround this error : We temporarily set DataMoveReplicationContraint to None
Set-mailboxdatabase DatabaseName -DataMoveReplicationConstraint None
Mailboxes moved to new databases without any errors instantly.
