Missing Body in custom Meeting Req form

[ML]

I created custom Meeting Request form and everything works but Body of the
form. I'm not altering Body in the code and don't have any reference to Body
in my code. But if I put any text in the body, appointment in my Calendar
shows the text but it's missing in a calendar of the person or the resource
that I invited to join with this Meeting Request form.
Any idea? I've tested it in both Outlook 2000 and 2002. It behaves the same.

Thank you,
