Exchange: Recover Hard Deleted item
- Message is deleted (paper is put in the under desk garbage)
- Delete items folder is emptied (the janitor collects the garbage and puts it in the dumpster)
- Exchange performs maintenance to purge the deleted items (the dumpster is collected by the garbage company)
At various stages the document may be recoverable, but it becomes increasingly difficult. Also, you can skip to the last step by performing a hard-delete (pressing shift-delete).

- Simply check the deleted items folder, and drag back into the correct location or simply open within the deleted items folder.
- Right-click on the deleted items folder and choose recover deleted items. However, if you performed a hard delete from a different folder (shift-delete) they will be stored in a different recovery location – more later.
- At this point, you are looking to recover from backups only.

However in Outlook 2003 and prior, this is a hidden feature which you must enable via a registry hack:
