Using New Outlook on Windows for professional communication and productivity
None of the "Message handling" options address the option that I want to use (and, it seems. that others on this thread want): mark as read after user has opened the email. Hovering/selecting or waiting 5 seconds don't actually mean I have read the email. I tried unchecking the box for "Keep unread unless I explicitly mark as read" but that didn't help. Microsoft, why? Please fix this.
Yep, exactly!!
