Fslogix and outlook 58tm1 problems

Hello,

I am in dire need of some help because i'm at my wit's end here.

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 dreaded 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).

The users are growing tired, the support guy is considering goat herding as an alternative and the higher ups are veeeeeeeery displeased. Problem, we can't fix this, not in a timely fashion, not cleanly or easily.

This seems to be an ongoing issue which has been present for years but got exacerbated lately with modern auth and subscription model shift for office. Is there some hope or do i have to start explaining to people how to type in their passwords? Because my next step would be to nuke everyone's aadbrokerplugin folder at the end of the day.

Thank you for reading my rant :)
