Outlook Express is a Microsoft email program that allows you to send and receive emails. You can access Outlook Express through your Internet browser, but only if you select Outlook Express as your default email program.
Choose Outlook Express as your default email program. From the Start menu in your taskbar, select "Settings" then "Control Panel." When the Control Panel box opens, click on "Internet Options." Select the Programs tab. In the list, you will see an option for email; select Outlook Express from the drop-down menu. Click "OK" to save your options.
Open your browser. On the top toolbar, look for an envelope icon. For Internet Explorer 7, the mail icon is on the right side of the toolbar that also holds the open window tabs. It says "Read Mail" next to the envelope.
Click on the mail icon. The Outlook Express program will open on top of the Internet browser screen. You can now use Outlook Express to open, read or send mail.
