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'.
