Need help moving ,dbx Outlook express messages to Outlook 2007

I need help moving ,dbx Outlook Express messages to Outlook 2007.

I backed my old email Outlook Express .dbx files to a USB drive. How do I
import my mail messages and sent files into Outlook 2007? When I try to
use the Outlook 2007 Import wizard, chose other files and then chose Outlook
Express 4.x, 5.x, 6.x and internet mail--- and then browse to the folder
they are in I get an error message that there are no internet email
messages.

I haven't tried this since I don't have Outlook, but it should work.

Make a new folder on your desktop called OEMail.
Copy all of the DBX files into it (including Folders.dbx).
Make sure they are not Read Only by right clicking their Properties.
Use Outlook's Import function.

In this case, you would transfer your OE data into Windows Mail, then export
it from Windows Mail into Outlook 2007. See here for further details - Importing DBX files into Outlook 2007

I would suggest you to use 'DBX to Outlook' program to move &
'import DBX to Outlook' or to 'import Outlook Express into Outlook'

You can try the program from the following link
