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

    We're running into the exact same issue, company wide when users are accessing Outlook through a Citrix machine their session locks up for 20-40 seconds and showing the "Outlook is trying to retrieve data from the Microsoft Exchange server" message.

    Happening multiple times a day to most of the company. Only seemed to start a couple of days after this month's patch Tuesday.

    I've tried everything I can think of but still no resolution.

    Installing the out of band patches for the Windows Kerberos issue has fixed some of the other problems caused by the patches, but this issue persists.

    Thanks Tom, good to know we are not alone.

    I have a case logged with Office365 support but it is moving very slowly. If i get a resolution i will post it here.

    This issue started before we had patched our Citrix servers with the monthly so i think that the issue is on the exchange side.

    HI Tom and Steve

    I have a case logged with Microsoft Tech support also. They keep saying to go into cache mode for 3 months display of emails. However, cache mode won't work for us. It causes us more issues. We need to be in online mode. We were fine until the major patch was released two weeks ago. I had to enable logging in Outlook and have just uploaded them to Microsoft for them to investigate.

    I will let you know if they come back with a resolution.

    Hi Steve and Lia,

    That would be great if you get an update from Microsoft, I might log a case with them as well.

    Only our Domain Controllers and a few other servers here and there have been patched to this point.

    Interestingly we still haven't patched our Exchange server just yet, our Citrix environment has only had the storefront servers patched, however these issues started prior to these being patched.

    We're in the same boat, can't enable cached mode as it causes a lot of other issues due to mailbox sizes.

    Hopefully we can get a resolution soon, cheers

    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.
