Importing backup messages .mbx to any new Outlook version

[Jose Lozano]

Hi,

I have a complete folder from winnt\profiles... \outlook
with messages that I need to import to outlook. I have
always had problems importing files. These extensions
are .mbx . they completely differ from the inbox.dbx or
sent items.dbx I used before.

I cant quite remember if it was MS outlook or Outlook
Express, but I need to import these files, give input,
anything, all.

Now im using Outlook Express 6, and can get MS outlook
installed. Please respond ASAP, these files are from 99.
