My team is getting ready to launch a training event in Teams with 20 attendees. One activity will require that the attendees break into pairs, and we have created 10 breakout rooms (channels) to accommodate this. Will the 10 channels be able to conduct video chats at the same time (10 simultaneous channel /video chats)? Thanks.
You van have them open at the same time and chats will flow in to the chat window as well. But once you switch from one meeting to the other you will be onHold in the other meetings. But if chats are needed only that will work.
There is no official limit to the number of concurrent meetings in Teams. It can handle 10 easily. The max number of meetings you can be joined (or connected) to at the same time is 4. But you can only have 1 active connection to a call / meeting. The other 3 would be on hold.
