    So I have a small update from Microsoft on this, and it's more of a temporary fix from what I understand.

     

    1. Login to https://endpoint.microsoft.com/#blade/Microsoft_Intune_DeviceSettings/DevicesEnrollmentMenu/enrollmentRestrictions
    2. Create a new Device Type Restriction
    3. Give it a name
    4. On "Platform Settings" change "Android Enterprise (work profile)" to BLOCK
    5. Make sure "Android Device Administration" is set to ALLOW
    6. Click Next
    7. Click Next
    8. Under Assignments click Add Group and select the group of users that are signing into devices.
    9. Click through to finish the setup

     

    Wait a few minutes, and reboot the phone, login again.

     

    I'm still trying to find out how to resolve the issue correctly, but this seems to have helped most of the cases I've had issues with so far.

This solution was already put in this thread by me. The point here is that using Intune is a workaround for the root issue. The logon loop when not using Intune is the real issue here. In fact when we started with the IP phones in 2020 there was no need to use Intune to connect the IP phones to the Teams Admin Center.
It was after an update of the Teams app that this issue started happening. I have been in a ticket about this issue with Microsoft since May of this year and there statements about the solution have changed a couple of times.
To me Microsoft does not want to admit they caused the issue in the first place. Our company want to manage the IP phones just like we manage other Teams Devices by just connecting them to the Teams Admin center. And not Intune, because that does not give an added value.

By they way this issue does not occur if you use AAD user accounts for the IP phones....
My ticket with Microsoft will remain open until the fix it.

    I'd like to also echo Jeroen's mention and that is please advise on what progress is being made to stop customer phones from looping on the sign-in page of company portal. My understanding is that the MFA is failing to reach the user and hence loops. I also know that MS have also repro'd this issue on their own kit as per case I have opened. What would be great is a site where MS has a 'what issues we are aware of and are actively working on'.
