As you know, Microsoft Teams is the collaboration hub from Office 365 allowing you to chat through instant message or setup and join meetings.
Well, a new capability has been added to Teams Channels; you can now immediately start a meeting with all members of the channel (either a meet now or scheduled meeting).
To start a meeting with all Channel members, just open you Teams client and access the Channel you want to start the meeting
Then on the top right you will see the Meet button allowing you to either start a meet now meeting or schedule the meeting
