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

Download participant list from Teams meetings

You will soon be able to download a participant list from within your Microsoft Teams meetings. This feature can be helpful to identify who attended a mandatory meeting, but also useful as a tool to identify users with connection problems. Multiple drops and reconnects can be a sign of network issues.
The feature is not enabled by default, and will have to be enabled by an admin with the following command: 
  • Set-CSTeamsMeetingPolicy - Identity Global - AllowEngagementReport "Enabled"
If you want to limit the availability of this feature, you will have to create a separate meeting policy, assign that policy to the users and then scope the above command to that policy.
This feature is available only from within a meeting, and should be rolling out already (early may, according to the admin message center).
