Insert Business Card in Outlook 2007 – Where does it get the contact list?

I have a customer who uses Outlook 2007 with Exchange 2003 on SBS. When she creates a new email and chooses Business Card>Other Business Cards it doesn’t list all of the contact folders for the organization. Other people do not have this problem. I logged on as a different user on her computer and did not have this problem. I created a new Outlook profile and the problem is still there. I uninstalled and reinstalled Outlook and the problem is still there. Is there some trick to rebuilding this data?
