I realize that this have been discussed already, but what is the official answer?
If i host a private meeting with a lot of participants, how can we enforce who is allowed and who is not?
How can we prevent the participants from invinting others?
Don’t give that pre-register-approve-deny or users-must-be-signed crap, anyone who enters a meeting can invite the whole world to join. Anyone with a link IS ABLE to join.
Can you disable the invite button?
Or create api methods so one can implement a way to whitelist participants?
