SYMPTOMS
When you send plain text from an Outlook client that has an Exchange Server as the backend with the Internet Mail Service configured to send plain text or HTML, the Internet Mail Service overrides the user's choice, and sends both plain text and HTML. When MCI Mail or other plain text mail readers receive a message as MIME/multipart/alternative, the recipient gets one e-mail message with plain text at the top followed by the same message embedded in HTML tags.
CAUSE
The Internet Mail Service doesn't get the sender's option in the message. As a result it, sends both the plain text and the HTML.
RESOLUTIONTo resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, click the following article number to view the article in the
