Cal.com allows you to control whether events can be cancelled or rescheduled after they’ve been booked. These options apply to both the organizer and the guest.

​
Disable Cancelling

When this setting is enabled:

  • Guests will no longer be able to cancel their booking via calendar invite links or email.
  • Organizers will also lose the ability to cancel the event from within the Cal.com dashboard or via calendar/email links.

This is useful when bookings must remain fixed once confirmed — for example, in high-demand or tightly scheduled environments.

​
Disable Rescheduling

When this setting is enabled:

  • Guests can no longer reschedule their booking using the links provided in their confirmation email or calendar event.
  • Organizers are also prevented from rescheduling the event through the dashboard or calendar tools.

Enable this if you need to lock in meeting times and avoid last-minute changes.

These settings apply to the entire event, and affect both parties. Use with caution if flexibility is important for your scheduling flow.
