    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.

Are you able to open a support ticket with Microsoft? Can you send me the ticket number as a message you've opened it?

    Don't know if this helps anyone, but I opened tickets with Microsoft Teams support, Azure support, and Yealink. So far, everyone is saying it's someone else's issue. This has been going on for about 9 days.

      It would be helpful if you can send me a message with the Microsoft Teams ticket details. I am a PM in the team, and would like to see this ticket.

        I sent the ticket information in a DM. The ticket with Azure was closed because it was a 'duplicate' ticket. Yealink also said it may be a problem with too many devices for the user, but only one is assigned and I have set my company limit to 20, so that should not be an issue. I am going to try to downgrade it today, similar to what jangliss did, to see if my problem is fixed.
