Well start off by setting up the E-Mail account on your new computer.
Then go to the old one and share both the Address Book and E-Mail Files. Now open the new Computers Outlook Express and click on the file then Import then Address Book then select from storage folder and point it to the NB's shared Folder to import from. After you have done this repeat the process but this time instead of importing the Address Book Import the E-Mail and when this is finished delete the E-Mail account on the NB to prevent it collecting any more incoming e-mails.
If you can not set up a shared folder you'll need to go back to the Network Setup Wizard and enable File & Printer Sharing before you can do the above.
