A Meeting which has been been scheduled and published in Past and ended. Any member or owner is able to join the old past meeting. Why is this feature given. It just creates confusion. The chat also gets appended in the teams for the past meeting.
What will come is a feature that allows only the organiser to bypass the lobby, so when the organiser ends the meeting and someone joins the meeting later they will be placed in the lobby until someone lets them in.
There is another uservoice asking for a "hard ending" of the meeting. If that is more what you want you can vote for it here.
