Reschedule links allow you to easily reschedule all of your meetings from your calendar, including ones booked outside of x.ai.
For meetings booked with x.ai: You'll be brought to a Reschedule screen on the Meeting View page where you can specify new date/time constraints for the rescheduled meeting. You can also add an optional message.
Reschedule links are added to your calendar on a rolling basis, going 15 days into the future. Reschedule links are turned on by default, but you can turn them off here: https://my.x.ai/calendars
If you turn off your Reschedule Link preference, no additional Reschedule Links will be added into the future, but the ones already present will remain there.
