How do I try and retrieve an email from Outlook 2016 if I accidentally deleted it out of my "deleted items"?

Follow these steps:

  1. Look below your Inbox to find the 'deleted items' folder
  2. Open this and search for the deleted item
  3. If you find the items, right click on the email and choose move. This only applies if you have not purged emails from your  'deleted items' folder
  4. If you have emptied your 'deleted items' folder, you can click on "Recover Deleted Items from Server" displayed in the Home menu in Outlook
  5. A list of the items that have not been purged from the email server will show and you can press "Restore Selected Items"
