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.

Pop-out meetings in Teams to be gradually rolled out

The already announced feature of popping out meetings to a separate window have received some updates. The feature itself will be rolling out, beginning early June. But it will not be on for all by default. Once it becomes available for your tenant, there will be a new setting available for the user (kind of "opt-in"). These settings are available by clicking your avatar on the top menu, and select "settings". It seems like this will only be a temporary setting, and will be a default for all by the end of August.

This is the timeline posted in the admin center:
  • June – New experiences are available and users can enable through settings.
  • July – Experiences are enabled by default and users can disable through settings.
  • August – Experiences are enabled by default and user controls are no longer available.
