We have 10 users who's mailbox has been quarantined and deemed "poisonous". In the registry for each of the mailbox GUID's, it has aMailboxQuarantineDescription that states the following:
NullReferenceException: MESSLDM.MessageViewTable.GenerateDataAccessOperatorForIndexPopulation,MESSLI.LogicalIndex.BuildPopulationQueryOperatorDefinition,MESSLI.LogicalIndex.BuildPopulateObjectIfNecessary,MESSLI.LogicalIndex.PrepareIndexImpl,MESSLDM.MessageViewTable.PrepareIndexes
I am trying to determine why the mailboxes were quarantined, but this is very cryptic to me. Does anybody have any suggestion on how to determine why the mailbox was quarantined? I see that the quarantines will all end between 2PM and 4PM today, but if they should somehow wind back up in the quarantine, I would like to determine root cause. Any information would be greatly appreciated.
