What’s New in Microsoft Teams | December 2019


As we near the end of 2019, we can’t help but reflect on all of the incredible ways that Teams has evolved this past year, and how so many of our customers were able to use Teams to help them transform their own workplace collaboration. And a big thank you to all of you who have implemented Teams at your own organizations, and shared feedback with us along the way! Read on to learn what’s new in Teams in the month of December.


Microsoft Teams is now available on Linux

Microsoft Teams is now available for Linux users in public preview, enabling high quality collaboration experiences for the open source community at work and in educational institutions. Users can download the native Linux packages in .deb and .rpm formats here. We are constantly improving based on community feedback, so please download and submit feedback based on your experience. Learn more here.

What’s New: Chat & Collaboration

Native Federation for 1:1 Chats with users outside your organization


Have richer conversations with people outside your organization with Microsoft Teams. Users in TeamsOnly mode can now enjoy the same familiar chat experience whether they are communicating with a colleague or someone who is outside of their organization. An icon will appear next to the user’s name to indicate that they are external.

What’s New: Calling & Meetings


Add captions to your meetings with the Live Captions Preview (English)Live Captions in Teams meetings allows you to turn on captions during the meeting. This makes meetings more inclusive, giving participants another way to follow along with the conversation, and addressing the needs of participants with different hearing abilities or language proficiencies. We have rolled out this feature to all of our customers in the commercial cloud as a public preview feature in English, and will look to roll this out in additional languages in 2020.

Dynamic Emergency Calling for Direct RoutingDynamic Emergency Calling for Direct Routing is now available as a part of Microsoft Teams Phone System. It uses the caller’s current location to route their emergency call to a Public Safety Answering Point (PSAP), a call center operated by the local government. This is especially helpful when the user is not in their home country and does not know how to get in contact with local emergency services. Learn more here.


Add additional participants to meeting chats

Today in private meeting chat threads (i.e. the chats that are created in association with a meeting), users don't have functionality to easily add more participants to chat. This feature will add an entry point "Add participants" in the meeting chat header and users who are already part of the chat thread will be able to add more users to the meeting chat using this feature. This functionality currently exists in group chat and it will work the same way as group chat.
