Resolved Transfer from Outlook to Outlook Express

I would like to transfer a large number of emails from my Desktop running XP Outlook to my Netbook running XP Outlook Express.
I have exported them successfully to a .pst file and transferred them using a memory stick.
When I try to import them I get the message 'Messages cannot be imported from the MAPI client'.
Any ideas what the problem might be?

 

Thanks Pete, tried your suggestion with the following result.
Method 1 was not relevant.
Method 2 gave the same error message as before.
Method 3: downloaded Windows Live Mail and tried to import emails in .pst file as before. It only gives the import options for OE 6 or Windows Live Mail or Windows Mail, not Outlook. None of these work.

 

Sorry Steve, but I do not understand your suggestion.
If all else fails, I have a copy of Office 2000 which inludes Outlook, so I will install that on the Netbook and I should then be able to import a .pst file.

 

I thought that is what you meant, but if you look at my original question, you will see that I have tried the obvious and it hasn't worked.

 

I have spent some time trying to get round this problem, but have now acheived some success. For the benefit of anyone with a similar problem if the normal export/import doesn't work, I have a program called Mail Navigator which will save mail from Outlook and Outlook Express. I copied this program across to the Netbook computer and it has retained all my emails in .pst and .dbx formats.
