For the moment, while you create a recurring or multiple booking within the Operate Calendar, you will not see a Conflict notification and each booking instance will show a validation checkmark. This means that it does not instantly tell you if there is another booking for your desired room and date/time.

Please click Confirm to allow Operate to check for conflicts. If there are any, you will be taken back to the booking screen and the conflicting instance will be highlighted. If there are no conflicts, the booking will simply save. 

If you see any conflicts, please adjust the booking.
