We have exchange 2010 setup and have a equipment mailbox setup for a pool car. We have run the following command in power shell to Configure the mailbox to automatically process meeting requests
Set-CalendarProcessing "pool car" -AutomateProcessing AutoAccept
Now this works fine and delines any requests made if the pool car is already been booked apart from if somebody had already booked it and had ticked the request as an all day event. So the new booking request is accepted but now there is a clash with the same period being booked out twice.
Does anyone know of a way to get the booking requests declined if there is already an all day booking request in place?
