My boss had Exchange Server installed at his office last year, then uninstalled it, and now wants it reinstalled. I, the new hire, have to put it back. I've never dealt with it before. Am I in over my head? Are there configuration options I won't have to worry about because the machine has had Exchange on it before?

Really I'm just seeking reassurance that it's not that complicated to understand. Only two people will be using it, in an office of 12... it can't be that difficult, can it?

Any good resources for people completely clueless about installing it?
