Hi Mark - I am probably late for this, but I don't quite understand the issue. For this type of thing I would call support and let them know you don't know where to cancel or delete a scheduled Webex meeting. If its open, it won't let you. Sometimes we set sessions to allow attendees in early that opens the session, hence we can't cancel it. 1-866-229-3239 is the 24 hour support number.
