New outlook for Windows not syncing read/unread status of emails

Here it is August 2024 and the old Outlook is going away leaving us with the new Outlook which doesn't sync correctly with IMAP. My issue is that when I read messages in the new Outlook, they are not marked as read in my Google IMAP e-mail on the web. Interestingly, if I read an e-mail online in my GMail account, then it DOES mark it as read in the new Outlook.

I would think this would be a simple fix but no one at Microsoft seems to care.

Hello,

In the new Outlook for Windows, the experience is generally good except for an issue where emails read in it still appear as unread when viewed in a different client, like the Outlook desktop app or the iPhone mail app. Any ideas why? Has anyone else experienced this?

To reproduce:

1. Open your Outlook for Windows and another client (e.g . Gmail)
2. Find a read email in the alternate client and mark it as unread
3. New outlook for Windows will update after ~10 seconds displaying the unread status - this is GOOD
4. Now try doing this the opposite way around - both marking an email as read or unread within the new Outlook for Windows doesn't sync to the actual mail server. It does maintain this unread state within the Outlook for Windows even after closing however.

It's annoying because if I go through my emails on my computer, then look at them later on my phone, it still shows all emails as unread.

Edit 28th Feb 2024: I have unmarked this as resolved because there are clearly many people with later versions who still experience this issue. Please sort this out Microsoft - it's incredibly annoying.

Thanks in advance,

Jonathan

My Outlook is not working to update the Gmail status "read/unread".

Problem still not solved.

It's unbelievable... isn't it? It almost feels like Microsoft is holding the public hostage...

As of May 8th, this is still a problem. Outlook does not sync read status of mail properly. The old Win 11 Mail did it just fine. I'm not sure why it's so hard to fix it in Outlook. I've done everything possible to get Outlook to work. Uninstall re-install, remove all traces of win 11 mail, try again, still it NEVER works.

Syncing read status is perhaps one of the most necessary features of a mail client. It's mind boggling that MS doesn't accept that it's an Outlook problem and it exists. You have a working example (win 11 mail) and a non-working example (new outlook). Should be pretty straightforward to work out how to fix it.
