Creating Breakout Rooms in MS Teams for Virtual Events

The best way to create breakout rooms in MS Teams is to create one Team that has channels for each breakout room.  The name of the Team should be the name of the event.  The name of the breakout rooms can just be listed as Room 1, Room 2, Room 3, Room 4.  The reason you want to keep it generic is because throughout the day, you'll have various sessions and you'll just indicate on the agenda which room each session is in.  

To schedule the virtual sessions

1) Go to your calendar and select "New Meeting."

2) Add channel for the room where your meeting will occur (screenshot below)

Once the conference is in place, go to the appropriate meeting room and enjoy your learning.
