Generating an Outlook meeting invitation from ColdFusion is a challenge. There are snippets of code here and there, but I finally got a working solution.
<cfmail to=”someone@someplace.com (Name here)” from=”someoneelse@someplace.com (Name)” subject=”Test appointment from ColdFusion” type=”multipart”>
<cfmailparam name=”content-class” value=”urn:content-classes:calendarmessage”>
<cfmailparam name=”Content-Type” value=”text”>
<cfmailparam name=”method” value=”REQUEST”>
<cfmailparam name=”charset” value=”utf-8″>
<cfmailparam name=”Content-Transfer-Encoding” value=”7bit”>
<cfmailpart type=”text”>
[Introductory blurb here]
</cfmailpart>
<cfmailpart type=”text/calendar”>

Note: If you don’t include the cfmailparts, and try to send the whole thing with content-type = text/calendar, you (well at least I did) will get the following error: IOException while sending message; nested exception is: javax.activation.UnsupportedDataTypeException: no object DCH for MIME type text/calendar; method=REQUEST
