I see about five of these events happening every minute on one of my store servers. It seems that these are outdated requests for a mailbox database that I have previously removed. They started to appear after I upgraded to UR2. The only issue is that it doesn't show what the request actually is so that I can clear it out. I had recently had some trouble with a Recovery database and restoring mailboxes but I've already deleted that database. I've checked:
Get-MailboxRestoreRequest (suspect it may be these since I had trouble with them), Get-MoveRequest, Get-MailboxExportRequest, Get-MailboxImportRequest
..and all show 0 entries. Is there a way of finding out what requests these are so that I can clear them out?
The Microsoft Exchange Mailbox Replication service was unable to process a request due to an unexpected error.
