Organizers and recipients have the ability to reschedule meetings booked through meeting types via a link in the confirmation email.
To enable this feature in your meeting type, go to its 'ADVANCED SETTINGS' > Check the 'Reschedule Link' box > Save Meeting Type. (This will not affect previously scheduled meetings that the setting was not on for.)
If the recipient or organizer reschedules the meeting, the other will receive a confirmation email letting them know the meeting has been rescheduled.
If you wish to disable this feature on a meeting type at any point, simply click on the gear icon to edit it > scroll to ADVANCED SETTINGS > uncheck the 'Reschedule Link' box > 'Save Meeting Type.'
