A room resource is nothing but a schedule-based booking system. It creates digital representations of physical spaces (or equipment). These digital areas can then be booked through a personal work calendar. Moreover, as the room resource adds a mailbox of its own the person booking the space gets to send out an automated message. 

Everything from resource name to the booking duration can be set up with a click of a few buttons. Additionally, resources can be in one of two categories: rooms or equipment. In our case, we chose a room. Overall Room Resource allows companies to avoid conflicts and work more seamlessly.
