This article describes how to send an e-mail message that contains a background sound. When you follow the procedures in this article, the sound is played automatically when the message is opened with an e-mail program that is capable of reading Multipurpose Internet Mail Extension Hypertext Markup Language (MHTML) mail, such as Outlook Express, Microsoft Outlook 98, or Microsoft Outlook 2000.
NOTE: The recipient must also have an e-mail program that is capable of reading MHTML-formatted mail to play the sound or a plug-in for the sound format that you choose.
You can use Outlook Express to format a Hypertext Markup Language (HTML) e-mail message with background sound. This feature is not available when you compose messages in Microsoft Outlook 98. However, recipients who use these versions of Microsoft Outlook can hear your sound. Microsoft Outlook 2000 and Outlook 2002 can do this when you compose an HTML formatted e-mail message with Microsoft WordMail as the editor. Use the Sound tool on the Web Tools toolbar to embed a sound file in the e-mail message.
The following table lists the file formats that Outlook Express supports for background sound.
