I’ve accidentally deleted a message which I liked to keep and since I have Outlook set to empty delete the Deleted Items folder upon closing Outlook, I can’t restore it from there anymore either.

I do make frequent backups of my pst-file, however, I do not want to lose any of my new emails which I’ve received or sent since creating that backup.

Is there any way to recover just that single message or the folder containing the message from my backup?
