Minimum Booking Notice
Set a minimum notice period to control how close to the start time meetings can be booked.
Enabling this rule will allow you to set a cut-off time in minutes for meeting bookings.
For example, if the rule is enabled and set to 10 minutes, users will not be able to book a meeting 10 minutes before or after the start time of the meeting. (If the time is 10 am, a user can only book the room up until 9:50 am).
