We are having an issue where Mac users that have the Enterprise SSO extension (Microsoft Enterprise SSO plug-in for Apple devices | Microsoft Learn) configured via an Intune Policy cannot login to any Microsoft App that uses it, (Teams, OneDrive, Company Portal). The fix is to remove the Policy that Intune pushed out... However Intune\Company Portal is now broke. We have had to completely remove Intune so that the policies get deleted. I have seen posts from others who have the same issue but no response from anyone.
