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.

A new feature in Teams: Share contact information in chat. And one feature change: Web pages will open in browser

Microsoft Teams makes it easier to share contact information for easier collaboration. Within a chat it will now be possible to use the @ mention to bring up a contact card you can send and share with others within your organization. Helping your colleagues connect with one another just got easier.

Another change in Teams, is how the "website tab" inside a channel behaves. In the coming weeks and months, webpages will no longer be displayed in the tab, but rather open a seperate web browser tab (your default). This is to better align with emerging best practices in web security and privacy while also improving the reliability of websites.
