Error code - caa30194

There's a more permanent way to sign in to Microsoft Teams. If you're having trouble completing the process, talk to your IT admin"

Our company has been using Teams  for a while, it works very well for me until today. I can't sign in Teams desktop in my computer after I upgraded my OS from Win7 to Win10. But the funny part is that Teams web and Teams in my Phone(android)  are still working very well. The desktop Teams feedbacks with error code: 0xCAA30194, which is attached below. Can anyone help with it? Thanks in advance.

1. Enter the microsoft page with your email that has Microsoft TEAMS permission.:

login.microsoftonline.com

2. Open app TEAMS and login. Acces ok.

HI,

I had the same problem within Teams but it is fixed now.

I hope this will help.

Steps:

* Uninstalled Teams

* Reboot Windows

* Installed latest version of Teams

* Open Windows Firewall settings and add Teams to pass-through Windows Firewall.

* Signed into Teams.

* Connected.

Tried absolutely everything on every forum I could find and could not get around this issue.

Then someone tried to login into Microsoft Store and got exactly the same message.

In the end I rang MS and held until I spoke to a support guy who ran through various tests for some time before concluding that my Windows Updates had somehow missed doing a major update some time ago but had carried on doing updates until there was something critical that it needed but there was no way to roll back at that point.

We tried various things and ended up clean installing Windows (10 N Pro) and now everything works fine. Bit of a pain creating new profiles for everyone who uses this PC + manually coping files from Window.old but everything else now works properly (and I have Office 365 and Teams apps installed on my local desktop).

So overall happy.
