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 is there an update on this issue? The steps you point out above are not helpful. There are several tickets open in this. This is causing Major disruption for our business during a peak period. Efficiencies are lost, staff cannot work effectively. This major disruption has been occurring since Office and Exchange update on 10th November.

    Also running into similar issue with one of my clients. Client has two shared mailboxes and doing a search causes Outlook to freeze. I also have a ticket with Microsoft about this.

    I've done a bit more digging, looks like our issues started on the 10th or 11th of November.

    We did not patch a single server in our environment with this months updates until the 17th.

    Not sure if something was changed on Microsoft's side of things that could be causing this.

    We have the same issues here. Dozens of clients with Outlook randomly freezing. The issues we're having is not just RDS type environments but Windows 10 Pro PC's too. Also they all use Cached mode and that makes no difference so I wouldn't even consider trying it.

    Is it even possible to roll back an Office Update as we're on the patch released the 8th November as well (15726.20202)?

    We are also expiring this issue since early November; we also run a Citrix environment and also have a direct connection via our internet service provider to Microsoft in an internet exchange. I don't know what it is, but caching is not an option for us as well. We service 2000 users and tickets are crazy atm.
