FSLogix Problem with Microsoft.AADPluginBroker

We have a few on prem windows 2022 RDS farms using fslogix and outlook. We are bashing our heads against the wall because of the this 58tm1 problem. Every once in a while (5 times a day) a user will get a 58tm1 error while trying to open outlook, we usually fix the problem by deleting the Microsoft.AAD.BrokerPlugin which would fix things for a short while, because we've tried everything else out there, nothing works.

 Every possible settings combination, registry fixes etc... Newest fslogix versions (hello 25.09) do not fix anything but break everything (this entire branch has a nasty bug which would create temporary profiles and fill every storage space available).

Let me know any possiblity to fix this =)

    Did yall get a "real" fix for this?  I've tried various things yet have been unsuccessful in getting the errors described in this article to go away... https://learn.microsoft.com/en-us/troubleshoot/microsoft-365-apps/activation/cannot-sign-in-microsoft-365-desktop-apps Is your situation similar?

    Ensure you're running the latest version of FSLogix. Although you've mentioned version 25.09, it's worth checking the latest version available, as developers often roll out patches that could address known issues.

      After 3 days, the error shows up again. For our environment it was not a permament solution...
