If you want to "POP" your Yahoo! Mail into your Outlook 98 or 2000 application, here's how:

1. From the Tools menu, select "Accounts." If you do not see "Accounts," place your cursor over the two arrows at the bottom of the list to display more choices.
2. Click the "Add" button.
3. From the Add menu, click "Mail."
4. In the Display Name box, type your name as you'd like it to appear when you send a message. Then click "Next."
5. In the Email Address box, enter your Yahoo! Mail address (for example, "user@yahoo.co.uk") and click "Next."
6. In the box labelled "My incoming mail server is a…" select "POP3" server.

10. In the Account Name box, enter your Yahoo! Mail ID (your email address without the "@yahoo.com").

16. If you chose "Connect using my phone line," you must select a dial-up connection in the Dial-up Connection Wizard and click "Next."
