Manage meeting safety settings

Lock the meeting for Friday’s parent-teacher night at 7:15 PM after all scheduled attendees are admitted, enable the waiting room so late parents must be admitted individually, turn off file transfer, and ensure screen sharing is host-only. Confirm each setting is active five minutes before start.

Before the big Q&A, make the safety settings transparent and reviewer-friendly: show whether the meeting is locked, who can join from outside the domain, whether screen sharing is restricted to hosts, and flag any setting that would block a speaker or slow admissions so the admin can approve quickly.

During our staff huddle an unknown attendee joined and posted links in chat. I’m worried we left screen sharing or chat open to everyone. What’s the most likely misconfiguration that allowed this, how do I immediately stop them from sharing, and what setting should I change to prevent this in future meetings without blocking parents?

Safety settings get reset or ignored each meeting, leading to interruptions, unauthorized shares, and repeated clean-up. Which single habit prevents most of this: a saved meeting template, a one-minute pre-meeting safety checklist read aloud, or assigning a safety co-host each time? Recommend the best option and a short script to implement it for the next month.
