The e-mail program you want to use needs to be the default e-mail software. You can find an option to set the default e-mail software under Settings > Control Panel > Internet Options > Programs. If not found, in Explorer, select Options under the View menu, and select the File Types tab. Select URL:MailTo Protocol, double-click open, and enter the mail software path and options on Application used to perform action. Refer to the e-mail program help because the options depend on each mail software. Some e-mail programs do not support this function.
