My Outlook (O365) and many others is constantly freezing. We are in online mode due to accessing shared mailboxes.

This issue started occurring after Microsoft released a big update on 10 November 2022. The message appears below everytime Outlook freezes. We can't be in cached mode as it causes issue with shared mailboxes. How do I fix this issue? thanks Lia

    HI Josh

    Thank you for the update. At least Microsoft are investigating it. Hopefully, it is resolved soon.

    So I have found something interesting after the support rep responded very quickly.

    He asked if all the computers affected were domain joined. When I thought about it, yes they are.

    I also ran SARA on 1 of the affected PC's I've been testing with and it found even thought it's the latest version of Outlook 365, it was running in basic auth mode. The tool changed it to Modern auth and also disabled hardware acceleration. We'll see how that goes next week.

    No word from the client yet (which is good news as she had sent a "it's still freezing" early every morning for the past week).

    I'll give it all of today and call her tomorrow for an update if I haven't heard today.

    Hi All,

    Latest from Microsoft, appears a fix is being rolled out.

    "Thanks for your email. Based on my confirmation internally, This seems to be a known issue which is being investigated by Microsoft Outlook Product Group already, and the fix is being rolled-out to customer tenants gradually. "

    Thanks again to Sujan
