How to Disable Adding Guests in Cal ID
Hide the Add guests option from your booking page so the booker can't add extra email addresses to the appointment.
- Strict 1-on-1s: keep the meeting between you and the booker.
- Manage group size: prevent unexpected attendees.
- Simplicity: a focused, single-attendee booking.
- Open Event Types and click Edit on the event.
- Scroll to the Questions section.
- Find the Add guests question and toggle it OFF.

- Click Save.
Note: this removes the option from the initial booking. A guest could still invite others from their own calendar (Google, Outlook) after the meeting is scheduled.
