I was recently searching my Outlook 2016 folders for a document I needed for a newsletter I edit and couldn't find it anywhere, even though I knew I had received it. I searched everywhere, including the Recover items and found nothing. They weren't in any folder and weren't deleted. After coming out of the Recover items, my Spam folder popped up with several messages. When I looked the Spam folder I found the message and several others from the same individual. I never moved them to Spam and have always received this person's emails in my Inbox. I am confused and wonder if this has happened to anyone else?
