There are mailbox databases that do NOT require a replica for various reasons - (it's an archive db, it's for testing, it's for research).
Concept would be to select a mailbox database, select edit the application monitor, select NOT monitor for Replication.
This is much like AppInsight for SQL server - which has the ability to not monitor specific databases for specific components.
oh, It would be great if a report of mailbox databases NOT being monitored for replication would be available or some type of indication that it is not being monitored for replication.
Thanks
