Teams Phone device refuse login with 1449/1.0.94.2021033002 firmware and ADFS
Has anybody been using ADFS with Teams noticed an issue with the last two firmware updates, when performing logins off-network? I have a customer running Yealink MP56 phones and the latest firmwa...
So I have a small update from Microsoft on this, and it's more of a temporary fix from what I understand.
- Login to https://endpoint.microsoft.com/#blade/Microsoft_Intune_DeviceSettings/DevicesEnrollmentMenu/enrollmentRestrictions
- Create a new Device Type Restriction
- Give it a name
- On "Platform Settings" change "Android Enterprise (work profile)" to BLOCK
- Make sure "Android Device Administration" is set to ALLOW
- Click Next
- Click Next
- Under Assignments click Add Group and select the group of users that are signing into devices.
- 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.
The biggest issue of all is that there's no way to stop these phones from automatically getting the update eventually! Deferring for 90 days is the best we can do and that's a very manual process to have to set each and every phone as they come in. Imagine how rough it's going to be when you have hundreds of phones!
Has anyone found a real solution to this issue? I am about to start rolling back firmware but was hoping someone has an answer.
- I've not heard anything back on our open Microsoft support ticket but the more people that open tickets, the more visibility this is going to get for quicker resolution.
- I'd definitely agree. Open tickets if you haven't already. I've not heard anything from support on my ticket other than "sorry for the delay, we're waiting to hear back from engineering".
