I use exchange with an imap client for work mail. That way I can use it offline on the client but it is all backed upon the server. Also, that way I can get at it on only of my computers that I have a client on or for that matter anything that has a browser. POP doesn't give me the flexibility. I gave it up years ago. Having the same thing on my computer I gave with me and the server works best for me.
