Repeat Bookings
When creating recurring meetings you can manage how many weeks in advance users can book with this setting.
Head over to Settings > Meeting Rooms > Meeting Rules (https://portal.clearooms.com/settings/meeting-rooms/rules).
From here, you can toggle on and off the 'Repeat Booking' option and set the duration in weeks.
Be sure to click 'Save' at the bottom of this page for the effects to update.
