check 4 POP inboxes and 2 exchange accounts w/ 2007

I have a very complex job where I must check email from 6 completely
different mail system.

Currently i have outlook 2007 configured to check 4 POP accounts from
4 completely different companies. (this works beautifully, no
problems).

Now, I want to set it up so that it will check mail from two different
Exchange servers. The last i tried this with outlook 2003 it
completely fubard the exchange account (somehow it copied all my POP
emails into the exchange inbox. it totally wreaked havoc on my
system).

Can somebody give me some advice on how to do this? I am willing to
pay for a working solution!
