Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello Phil,
It's not anything you are doing - it's Outlook. Outlook doesn't process the Ok from the IMAP server when it syncs the read state back to the server until you change messages.
My solutions are to Read mail in the reading pane and don't mark it read automatically. If I do mark it read, go to the next message and move or delete the messages later.
