As promised, a Microsoft Teams preview is now available via the store. For now, the app is exclusive to Windows 10 S Insiders, but it does offer some advantages. Namely, a deep integration with Windows 10,  supporting automatic updates, Narrator, Action Center, and more.

Th app makes use of web platform enhancements that came with the Windows 10 April 2018 update. Thanks to Edge, Microsoft has implemented progressive web app support, allowing developers to publish them in the store. As you would expect, Microsoft Teams fits that category.

New Features and Limitations

The release combines with a number of developer-focused improvements for Teams announced at Build 2018.

  • Apps in Chat—coming soon to developer Preview, you can now update your app so that it can be used in private 1:1 and group chats. Your users can add a tab or chat with a bot in their private chats to light up new collaboration and sharing scenarios.
  • SharePoint pages in Teams—SharePoint is now even more deeply integrated into Teams—with the latest integration you can pin a SharePoint page in your channels to enable deeper collaboration around sites and other SharePoint content, and get the full power of the SharePoint app platform within Teams.
  • Adaptive card support—coming soon to developer Preview, you can now send rich Adaptive cards from your bot, connector, or messaging extension. Adaptive cards allow you to send more flexible content in conversations and are supported on other Microsoft platforms such as Outlook, Windows, and Cortana.
  • Files support for bots—coming soon to developer Preview, your bot can now send and receive files in 1:1 chats with users. Enable content and document scenarios such as expense reports, file management, and image processing.”

However, Microsoft stresses that PWA Teams is an Insider app and has a number of issues. As well as freezes, you’re unable to schedule meetings from Outlook or use the zoom feature. If you can live with that, it’s well worth grabbing from the Microsoft Store.
