Does anyone know how to network Outlook?

Does anyone know how to network Outlook?
What I want to do is make my outlook calendar available to other people in my office so, if when I am out, someone takes a call for me, they do not have to come running across to my computer to see when I will be next available.
Any suggestions

 

It sounds like an office setting so can you share files or are all pc's stand-alone? Normally if everyone is going through a server everyone can access another's calendar. Under file in Outlook go to open, then to "open other user's folder" and a window will open with a pull down arrow, look for the name and pick calendar.
