Moving to Microsoft baselines since CIS has apparently stopped developing baselines for Office. But looking at the M365-2104 GPOs, it appears the registry location for Office 365 is the same as Office 2016 so now I am not sure. I would have thought the registry location for settings for M365 would be independent of Office releases or on par with Office 2019. So every M365 app will still use 2016 registry locations going forward?
@EddieRowe the registry location is indeed the same. Since v2016 Group Policy has shared the same registry path in Office between versions. That being said, there are new settings that are added that do not always backport to 2016, 2019, etc.
