Email on Gmail account are not getting marked as read

I've checked again this morning -- If I select the email in the new outlook client and navigate to another message, with Settings -> Email -> Message handling -> Mark as read changed to "Mark displayed items as read when the selection changes", then the message is marked as read appropriately on the servers. Again, I've tested this with a Gmail server and a standard IMAP server.

I have Microsoft Outlook Version 1.2023.1018.300 (Production). And Client Version is 20231020006.20 .

You can check you version in Settings -> General -> About Outlook,

The only caveat is I did change other settings at the time (namely "Show email grouped by conversation" and "Sort Messages into Fcoused and Other" in Settings->Email->Layout (for all my email accounts). And in Email->Message handling, I have "Always keep items unread unless I explicitly mark them as read" selected too). So you may wish to change some of those settings as well if it isn't the setting I mentioned earlier.

However, mark as read appropriately triggers the flag change server side when marking as read on selection change.

Unfortunately, it does not. The messages remain as unread on both GMail and IMAP servers.

Just the fact that this issue is now on page THREE and according to you is finally fixed is exactly why I've uninstalled both outlook and windows mail, and went all in on Mailbird. I've been fighting with Microsoft over email since 2015, and I'm just tired of it. Just like my web browser, map program, your phone app, MS Teams, and now email, Microsoft lost me. That's OK, I love Windows 11 and my Surface products. And now, I'm bowing out of this thread. I sincerely do hope that MS figures out email someday. Take care.

That's always worked, most of the time anyway. When an email shows as read in Outlook, go check on the email service's webmail. It still shows as unread there, and that's the problem. It works flawlessly with MailBird though.

RTA please: "... fixes the problem... both Gmail and IMAP". So I'm clearly not talking about mark as read just appearing to work when set in Outlook - or why would I even be here on this question?

Changing that setting means the mark as read flag is appropriately set in the server and is therefore updated in Gmail client too. You know, how it should work regardless of whether you mark as read on open or on selection change.

To summarise: mark as read still fails to properly trigger server side, only appearing as read locally in Outlook, when marking as read on message open. However, mark as read appropriately triggers the flag change server side when marking as read on selection change.
