Ok, so I have Office 2007 Professional Plus. It is supposed to have Office Communicator 2007, but I can't seem to find it, or figure out how to work it. It doesn't seem to be a separate program, or an install option. So how do I use it? The Office website doesn't seem to be too clear on it either. :(
Just use another IM program, or netsend for internal network use, considering that's essentially what the program does.
What do you expect? The product is aimed at businesses and large networks for easier internal communication; it's designed for people to quickly and simply share information with those they need to, not to chat all day to boost their social life.
