copy outlook express address book contacts to outlook for 2 ident.

I had 2 identities set up in outlook express and decided to switch to using
outlook instead. For the main identity, all of the information in the
address book was able to be imported into outlook without any problems.
However, for the 2nd identity all of the address information has been lost.
When I log in as the 2nd identity, I can't find any address information in
either outlook express or outlook. How can I retrieve the addresses for my
2nd identity?
