Method to follow if you have Outlook Express 6
If you already have Outlook Express 6 installed on your computer, we recommend that you use Windows Live Mail instead of Outlook Express 6.

This means that you can access, read, and compose e-mail messages even when you are not connected to the Internet. Windows Live Mail works with popular Web-based e-mail services such as Hotmail, AOL mail, Google mail, and Yahoo! mail. Windows Live Mail is built to automatically configure many popular e-mail services.

To install Windows Live Mail, visit the following Microsoft Web site.
