Think I must be missing something here-sorry. By "Outlook data file"
do you mean the Outlook.pst file generated by Outlook 2003. If so, I
can open this fine in Outlook 2007 with FileOpenPersonal Folder
File, and can access the email messages, the folder hierarchy etc
exactly as in Outlook 2003. But no contacts.

Are you looking at the Mail view in the Navigation Pane? If so, then
naturally you won't see any Contacts because Contacts folders aren'e mail
folders. Switch to the Folder List view and you should see the Contacts
folder.
