Use software to do this for you it easier
The easiest way to do this is to use synchronization software, there are many out there but the only one i have found that does emails, files and favorites is Dmailer sync.
Synchronzie all your email data from Outlook, Outlook Express or Windows Mail and then save it to a memory stick if you need to change computers. Then you can then transfer you email to either Outlook, Outlook Express or Windows Mail.
Using this software will not cost you because you can do this within the free 30 day trial period.
You can download it from:
