For some reason, the Microsoft Teams app on Windows 10 S is separate from the normal app for Windows 10. Because of this, Microsoft has to maintain two separate apps, one for Windows 10 without S mode, and the other for Windows 10 S. Or rather, that used to be the case.

Spotted by Petri, starting November 29 Microsoft is killings its separate Microsoft Teams app for Windows 10 S. This means that Windows 10 S users will have no choice but to use the web client from then onwards, as there will be no dedicated app for Windows 10 S users to use.

Why Windows 10 S can't just use a packaged version of Microsoft Teams for desktop is unknown. Regardless, if you're one of the few users using Windows 10 S and Microsoft Teams, you're going to have to either turn off S mode, or use the web client instead.

Many Windows 10 S naysayers will call this a big sign that S mode is dead, and I don't blame them. Yet again, Microsoft is failing in a unified message for Windows 10 S. Why should anyone else support Windows 10 S if Microsoft doesn't?
