I've been an admirer of Zimbra for sometime but thought my company would never go for it as we would have to revamp the way we work. It was only after an afteroffice.com salesman came to do this presentation that everyone saw the greatness of having such a system instead of just downloading individual emails via pop3 to our ms outlook.

However, I do not know where to begin.

What should I be doing/preparing for zimbra?
