POP3 Email on Droid and on computer's Outlook

Question

We have some personal POP3 email accounts with an internet service provider, and we've been using MS Outlook to retrieve and manage them.
We just got a Droid X, and set up these personal email accounts on it, and after some struggles finally got emails to start coming into the Droid.
HOWEVER, whatever mail messages go the Droid are now NOT going to Outlook like we want it to. Before the DRoid, we had a BlackBerry, and the emails worked fine, all emails going both to Outlook and the BB. But now it looks like each email only goes to one or another.
What can we do to make sure the emails go to both?
