With the release of build 17133 of RS4 (Windows 10 1803), I have began testing application compatibility for the inevitable rollout to our organization. I have discovered that when trying to install Microsoft Teams, Windows Defender SmartScreen flags the app as unknown and when telling it to install anyway, it says the application is not compatible and to contact that software publisher. Can we expect Microsoft Teams to work correctly before general availability of RS4?
