Hi @Karolis Peckus ,
The error often indicates that there is something wrong on the admin setup side of things. It can be resolved if the admin changes the MDM user scope and MAM user scope to "None."
You will need to contact your admin or IT department and have them change the MDM and MAM settings to None. After that, you should be able to sign in with your account on this device.
Otherwise, this can happen if there was a network change that might be preventing the setup.
If you are seeing the error in Teams, you can also try the troubleshooting steps in this video. https://www.youtube.com/watch?v=onMKkhOBoGs
Let me know if this helps. Most likely this will need to be resolved by your IT admin.
