If you accidentally delete Outlook items like emails, calendar appointments, contacts, or tasks, you can often recover them from the Deleted Items or Junk Email folders. Even if the Deleted Items folder is emptied, recovery might still be possible.
- Check the Deleted Items folder for the missing item.
- If it's not there, follow the steps on the Microsoft Support page to recover deleted items.
