Prevent participants from externally sharing Teams meeting join link.
We are using teams to run synchronous lessons. Students who are in the meeting are sharing the meeting link with their friends who now enter the meeting (teacher is teaching and doesn’t notice because the chat is not monitored at the same time you are lecturing/ screen sharing) . Next thing is obscenities etc. The ms teams meeting is “zoom bombed”. I need to be able to close the meeting within the first few minutes or only let students in whose identity (student number) I recognize.
