Announcing Teams JS SDK v2 in public preview: Extend Teams apps across Microsoft 365

Zakiullah

Following up on our recent announcement at Ignite, we are excited to share the availability of the Microsoft Teams JS SDK v2 now in public preview, which unlocks the ability for developers to begin extending Microsoft Teams apps across Microsoft 365. Now, apps built for Teams not only run everywhere Teams runs, but also in more of the places users spend their time in Microsoft 365, like Outlook and Office.com. In time, this means that developers will have the ability to reach hundreds of millions of Microsoft 365 users and support a hybrid world with a single code base.

Using this new branch of the Teams JS SDK, you can now extend your Teams’ personal tabs to Outlook and Office.com, and also extend search-based message extensions to Outlook. Meanwhile, Teams app capabilities like bots, configurable tabs, webhooks, connectors, and action commands will continue to work within Teams when using the preview version of the SDK and the app manifest. Also, the Teams Toolkit Preview now provides an option to guide through the process of extending new or existing Teams app to start exploring the new capabilities of Teams JS SDK v2.
