Join Teams work meetings from Microsoft Teams (free) and vice versa

Microsoft Teams (Free) users can currently join Teams for work (or school) meetings only as guests, which requires them to use a browser and results in a sub-optimal experience. The new feature rolling out will allow these users to join Teams for work (or school) meetings in one click, without being redirected to the browser or asked to fill in their name/surname. They will also be able to continue collaborating with the meeting organizer and other participants via meeting chat after the meeting.  The feature will work in the opposite way as well, so Teams for work (or school) will just as easily be able to join meetings hosted by a Teams Free user with one click. This is associated with Roadmap ID: 167326

A better Together Mode with content view is rolling out

There is a new layout for Together mode and content share rolling out to tenants. With the new layout, Together mode will be displayed under the shared content, allowing users to see both the participants in Together mode and the shared content simultaneously. The new Together mode will support raised hands, reactions, and name labels.

The new layout is available for Mac and desktop users worldwide (standard multi-tenant), GCC, GCC High, and DoD cloud instances. 

This announcement is related to Microsoft 365 Roadmap ID 181615. And according to the message center, it should be rolling out late January and early February.
