Question on connectivity of the following three things

I have a question regarding the connectivity of the following three things: outlook, yahoo mail, and a lot of computers on a network. I recently installed outlook at my computer at work. It then generated all my emails at yahoo mail. Is there any way I can do this with all the other computers at my workplace?
I want to have a uniform setting or email on all the computers. If this could be done, what if I remove an email in one of the computers in outlook? Would all the other computers be affected? I.e., will they be updated also?
