One of our techs was doing message archiving and got confused on a greater than and less than sign. and deleted an entire years worth of messages from our HR managers mailbox. Unfortunately the exchange database had not been backed up for a week. Before I go through the restore process I have been trying to recover those messages using the following two commands.
Search-Mailbox hrmanager -SearchDumpsterOnly -TargetMailbox "RecoveryMailbox" -TargetFolder "HRManager" -LogLevel Full
I also tried:
Search-Mailbox hrmanager -TargetMailbox "RecoveryMailbox" -TargetFolder "HRManager" -LogLevel Full
Each one gives me a bunch of history from the mailbox but does not give me the 2013 year I am looking for. I also did it with specifying messages only received in 2013 and did not produce any results.
Our retention policy on the server is set to 180 days on deleted items. Can I recover these messages without going to the backups? I always though you could but now have not been able to do it so am perplexed.
It is Exchange 2010 SP3 Standard.
