Rooms can be limited to how many days in advanced they can be booked. This limits the problems if a room usage is changed and helps find available rooms.
When a room is booked in a repeating meeting and dates fall into the limited time frame, only the dates too far in advance will be not booked. The other dates will still be ok. The person reserving the room will receive an email like this in return:
Please set yourself a reminder to book a room for the repeating meeting when it gets closer to the date/time that was declined.
In general we will limit the advanced reservations to 180 days.
