It has come to my attention that old meeting links are still active and can be joined by anyone. This generates email notifications to the meeting organizer that attendees are waiting. Recently we have been seeing these emails from unknown attendees like people are trying to hijack meetings or trick organizers into joining. How do we deactivate old meetings? What is the purpose for even having them active in the first place? These are not recurring meetings and are over a month old. I have submitted a support case as well and so far have not made any progress on that front.
