When you suddenly delete an item from your Outlook mailbox, you can often recover it. This is the best way to find Deleted Items folder. If you can’t find it there, the next place to look is the Recoverable Items folder, which you can access by using the Recover Deleted Items tool or Junk Email Folder. In such cases you can recover items after the deleted item folder is empty.

If you don’t see the deleted messages, which you want to recover, they have probably been permanently removed from the Deleted Items folder or Junk Email folder. We don’t recommend that you use either of these folders to store your messages.
