Great news! If your Business Mail and Yahoo! Mail addresses are associated with the same Yahoo! ID, you can manage them both from the Yahoo! Mail interface, and easily switch between accounts. To do this:

1. Sign in to your Business Email account at http://mail.yourdomain.com/ (be sure to replace "yourdomain.com" with your domain name). You'll be prompted to enter your Yahoo! ID and password if you haven't already.

2. If you're using the new Mail interface, you'll see a section called "Available Mail Accounts" on the left side of the page. To switch to your free Mail account, click the email address ending in "@yahoo.com."

   

   You'll see a "Logging in to Yahoo! Mail..." message as we switch to your free Mail account. To switch back to your Business Email account, return to the "Available Mail Accounts" pane and click your Business Email address.

Note: If you're using the original Mail interface, click the "yahoo.com" link under the "Mail Accounts" heading on the left side of the page.

Note that while you can switch between your Business Mail and free Yahoo! addresses anytime, you cannot switch between email accounts linked to different Yahoo! IDs. If you have accounts associated with different IDs, you'll have to sign out of the first account, then sign in to the second using your other Yahoo! ID and password.
