I need to migrate all the contacts from Outlook Express 6 on a Windows XP laptop to Outlook 2003 on a Windows7 laptop. The address book in Outlook Express has several subfolder and address cards each with their own set of contacts. When I export, then import into Outlook, the tree structure is lost and all I get is the list of contacts at the root of the address book. How can I move the whole structure into Outlook? Thanks.
