Importing PST Mail from Outlook to Windows Mail

I did a lot of online searching and believed the answer to importing
saved Outlook 2003 emails to Windows Mail lied in downloading a trial
version of Outlook 2007 onto my new computer , and the import the PST
file into the trial outlook, then supposedly the driver or whatever
would be downloaded to make it possible to import the mail from
outlook 2007 into Windows Mail, but I still get this error:

Messages cannot be imported from the MAPI client. MAPI is not
installed on this computer or an error occurred while initializing it

Any help would be appreciated. It burns me up that microsoft is trying
to blackmail me into paying $100s for Outlook .

I had a terrible time with this too, but I finally learned how to find my
email hidden files in my original email program and change them in the
control panel to non hidden files. Then you have to find them and save a
copy to your documents file on your original computer. Then you move them
with a flash drive to your documents file in you new computer using Vista.
Then you go into your mail program in Vista and import them from your "my
Documents" in the new computer. This took me days to learn and do but it
worked. Go to your help files in your outlook program to learn how to change
your hidden files from non hidden to start with. If you need more help, I
will try to help you find the info.

If you have Outlook, why not use it on the Vista computer? Ver 2003 works
fine.

But, in order to transfer, you need to install Outlook, copy the .pst file
over, and open it in Outlook.
Then in Windows Mail, import

Then you could download the Office 2007 trial, install it, open the .pst,
and import it into WM.

Or, take the .pst file to a friend who uses Outlook on XP, open the .pst in
their Outlook, open their Outlook Express, and import from Outlook. Take the
..dbx (messages) and .wab (address book) files to your Vista computer and
import them into WM.

You can only open a .pst file with Outlook.

I have the dbx file on a thumb drive, but can someone tell me how to
import them into a document? It doesn't work to do a direct import
from the thumb drive into Windows Mail, but someone above mentioned
something about putting it into a dcument.

You usually have multiple .dbx files, one for each folder and the one that
contains the folder info.

Copy them to the C: drive, open WM, and when you import them, DO NOT open
the folder that contains them.
