View Color catergories in Outlook 2003

We have some machines with Outlook 2003 and Outlook 2007. If we use colored flags in 2003 we can see the corresponding color category in 2007, but if we select a color category in 2007 we cannot view the color in 2003.

Is there something we missing or another method where both 2003 and 2007 can use the same color coding methods either using colored flags or colored categories?

When I try to move emails from the Inbox of the Mailbox of the Exchange Server to the Inbox of the Personal Folders (.pst) I get an error that says:
