The way you turn off Self-Book is very similar to how you set it up to begin with. (If you don't want to turn it off completely, though, you can also choose to edit who has access to your Calendar, reject an individual Calendar sign up/suggestion, or you can simply delete an existing Event. You always have full control over your Keep&Share Calendar and Self-Book bookings).
Turning off Self-Book completely in a Calendar
Turning off an “Appointment” or “Group Sign Up” template
Turn off the booking functionality to the Event on your Calendar by clicking on your event, clicking on the "Event Type" drop-down menu, and then selecting the "Standard" event type. Save your changes.
Turning off a “Make a Reservation” or “Suggest an Event” template
Turn off a “Make a Reservation” button by returning to the “Customize” screen and choosing the “None Selected” option on the drop-down menu in the “Self-Book” tab. Click the “Save & Exit” button at the bottom of the “Customize” screen to save your changes.
