Microsoft is going to make its Teams app available in the Microsoft Store starting in May 2022.
Microsoft officials added an item to the Microsoft 365 roadmap yesterday, April 20, which mentioned the Store availability. (Thanks to Neowin for pointing out the addition.) The roadmap item notes:
"Microsoft Teams app for work, school and life will soon be available to download from Microsoft store. This app will support work, school and consumer accounts on Windows 10 and Work or school accounts on Windows 11."
Microsoft has been working on a "Teams 2.0" client, which will be a Webivew2 one rather than Teams' current Electron-based one. It's not clear if the Teams app that ends up in the Store next month will be the expected new Teams app or the same one that currently is available for download via the Web.
