If you’re using a work or school MS Outlook email address (or any other large organization), your email may be backed up onto a Microsoft Exchange email server. Depending on how your administrator has your system set up, your “permanently” deleted items are stored on the email server for a defined period. This means that you may be able to use the Recover Deleted Items From Server tool to retrieve email Outlook messages even after they’ve been “permanently” deleted.

To use the Recover Deleted Items From Server tool, click on the icon in the Ribbon (it looks like a recycle bin). The Recover Deleted Items popup displays showing all the deleted messages stored on the server. Click on the messages you want to restore. Click the Restore Selected Items toggle and click the OK button. The messages will be restored to the folder they were deleted from.
