How Do I Make Yahoo! My Default Email Program?
When you set Yahoo! Mail as your default email program, it will automatically open up every time you click on an email link to send someone an email. This feature only works for Internet Explorer. According to Yahoo!, people who want to take advantage of this email setting must first download Yahoo! Toolbar version 7.2 or higher. It not only helps you set your default email program, but it also helps you stay on top of the latest news, weather and more.
Launch Internet Explorer and visit the Yahoo! Toolbar page (see Resources). Click on the button labeled "Download Now" to begin downloading the toolbar onto your computer.
Click the "Start" menu in the lower left of the computer screen. Select "Control Panel" and select "Internet Options." This will generate the Internet Properties dialog box.
Select the "Programs" tab and select "Yahoo! Mail" from the email pull-down list. Click the "OK" button to save your changes and exit out of the Internet Properties dialog box. Yahoo! Mail has now been set as your default email application.
