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

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".

For me it works with gmail accounts too - my primary email and a separate company gmail.

Seems to work okay with my Microsoft email account. However, it does not work with my Goole amil account.

yes! this has worked for me for a few days now. Just waiting to see if it's a permanent solution. Pretty stupid check box anyway.

Well said! 🙂
