User must have CALENDAR_VIEW and CALENDAR_MODIFY permissions. User can LOCK (obtain exclusive access) to a calendar by issuing this API. The LOCK will be in effect until UNLOCKED by the user, or until the user's APIToken times out (session timeout, default 30 min). A lock is required to modify or delete the calendar.
