I want to understand clearly how deleted items are handled by Exchange server.
When a user delete an item from any mailbox folder [inbox,Drafts,Outbox,etc..] it goes to Deleted items folder. If a user goes to Deleted items folder and delete the same item, it will Show up in Recover Deleted items. Up to this point, I believe the message is still in "Mailbox" of the user, as long as the online defrag or also called online maintenance process has not run yet and the expired number of days to keep the deleted items has not reached.
Now I need to know if a user goes to Recover Deleted items and purge selected item, before the online maintenance process kicks in, is this item recovrable without resorting to the Backup?
I believe the online maintenance will remove the deleted items that only have gone beyond the number day of expiration, to my understanding when purging the delted item from Outlook, the item is removed from the database regardless of the number of days to keep the delted items, and if the item has not been backed up before, it will be unrecovrable.
please correct me if I am wrong.
