A while back we have disabled Teams installation with Office install/update using GPO: Configuration > Policies > Administrative Templates > Microsoft Office 2016 (Machine) > Updates - Don't install Microsoft Teams with new installations or updates of Office
This worked and Teams was not installed automatically anymore. Now we want to remove this block. So for testing i created a higher priority GPO and changed this option to Disabled. Applied this GPO to my test machine and it shows in gpresult, that this setting is now Disabled instead of Enabled.
I have also uninstalled Teams from my test laptop (both user and machine wide install).
I have since checked for updates and updated Office a few times. I was expecting Teams to be installed now when Office does updates. But it is not. So i wonder why and if it is expected. Maybe it only does this once and if you have removed Teams it is not trying to install it again? Or maybe this only happens for new users?
