You can't import DBX files into Outlook. You must load them into Outlook
Express (or Windows Mail) and then export the messages to Outlook from
there.

I found that the actual email addresses of email headers shown
in outlook express can not be imported. Therefore, inside Outlook
2003, I found email headers left only the name of sender and
receipient, this is particularly obvious with quoted messages of
forwarded or replied email.

Load them into Outlook Express, export them, and your messages will be
intact.
