Add guests' permissions

I have an all-hands planning session next Wednesday at 3:00 PM. Add the team of 24 as guests and give them permission to see the guest list and modify event details, but prevent them from inviting others. Make that change now and confirm two managers retain organizer-level control.

Before I send the invite to the department, make it approval-friendly: display clearly which guests can edit the event, which can see the guest list, and which cannot invite others. Highlight any people who will lose organizer privileges and explain how that will affect their ability to move the meeting or add rooms.

I gave the marketing team permission to modify event details and now one person repeatedly edits the agenda without warning. I expected collaborative edits but not unilateral changes. I cannot tell who to call out without looking accusatory. What's the most defensible change to guest permissions that stops surprise edits but preserves quick collaboration for two deputies?

I keep toggling guest permissions to curb rogue edits, but meetings either become too locked-down or constantly rewritten. This wastes negotiating time and damages trust. Which habit should I adopt — a standard permission template, a two-person editor rule, or a pre-send checklist — to keep agendas stable while preserving necessary collaboration?
