Nuriye540, just to clarify, you can still manage corporate mobile devices without GMS, and we will maintain device administrator support for devices running Android 15 or earlier. However, this support will be limited.
AbhishekNL, For Microsoft Teams devices, these will be migrated to AOSP user-associated management with a firmware update in the third quarter of the 2024 calendar year in the first half of 2024. Please note that policies will not be migrated automatically, so you will need to create new policies for AOSP management. As mentioned by Graham Walsh, we have also published a blog that should be helpful: Moving Teams Android Devices to AOSP Device Management. Hope this helps!
