I receive my Comcast email through Outlook 2003. However, recently I have received a minimum of two copies of every single email that I get. Occasionally, I get three or four copies. The sender doesn't matter; it could be from my husband or from amazon.com. I just get two of everything. Any ideas?

This happened to me once, turned out to be related to Email RULES and ALERTS.

Click on TOOLS > RULES AND ALERTS

Examine any email rules you've setup. You might try turning all of them off and see if the problem goes away. Turn back on a few at a time until you spot the problem rule.
