Creating resources such as projectors, conference rooms, or training areas helps reduce double booking and other conflicts.  Exchange Online Services through your BPOS account by Microsoft Online Services allows you to create a shared resource such as a conference room or projector.  Doing so is easy and once created these resources can be seen in both the Outlook desktop client in the calender area as well as in Outlook Web Access (OWA) by setting up a new meeting, adding the resource as an attend and checking the associated free/busy information.
