What if, then, if you want to make sure an item cannot be recovered, let alone easily? You can empty the trash, of course, and the item is gone, but you still have to move it there first, and all other emails, contacts and what not in Deleted Items will be gone as well.
Fortunately, there is another way.
Permanently Delete a Message in Outlook
To permanently delete a message bypassing the Deleted Items folder in Outlook:
- Hold down the Shift key while pressing Del.
- Click Yes.
(The same works with entire folders, too.)
