Managed Schedules are editable by assigned hosts?

There isn’t a separate setting you’re missing for this—under Zoom Scheduler > Managed Schedules, the expected behavior is:

1. Assigned hosts should not be able to edit the managed event’s details (only the schedule admin should be able to change the managed schedule’s event details).
2. Assigned hosts effectively get their own copy of the event, so changes made later to the managed schedule don’t automatically propagate to hosts’ existing assigned copies.

So what you’re seeing breaks into two parts:

A) Assigned hosts can edit anything

That’s not expected for a managed schedule. The two most common “it looks managed but behaves editable” causes are the following:

• The hosts were assigned to a regular schedule/event (or a duplicated event) rather than the Managed Schedule object itself.
• The hosts have a role/permission that still allows editing (for example, they’re not account admins, but they may have Zoom Scheduler permissions that effectively make them schedule admins for that managed schedule).

B) Changes don’t propagate unless you unassign/reassign

That aligns with the “each host has their own copy” behavior. Reassigning forces a fresh copy to be created/updated for that host, which is why you see it “propagate” only then.

One clarification so I can give the right next steps

When you say “assigned hosts can edit anything,” where exactly are they editing it?

• In the Zoom Scheduler web portal (editing the booking page / event type), or
• In the calendar invite (Outlook/Google) after it’s booked, or
• In Zoom Meetings (editing the meeting that gets created from the booking)?

So after I create a managed schedule and assign it to a host, they effectively get a their own copy of the event. But they are allowed to edit their own copy of the event-- change any details about the event, structure, notification settings, etc. They are not editing the master managed schedule, but they are editing their own copy of the event.

It seems like the purpose of a managed schedule is to create consistency when several people will be holding the same types of meetings, so that you can create one version instead of each individual user having to create their own versions. But there is no way to enforce that consistency when people can edit their own copies, or when we can’t make changes to the event and have that propagate to the hosts the event is assigned to.
