Ah, this makes sense. I've checked the email headers and the 
"Content-Disposition: attachment" is in fact not there with the patch 
applied, so that's working but the Outlook versions I'm using still 
don't recognize it as a calendar event.

My test event's have only had one line in the description, but I've 
applied this patch and tested just in case, still no go.

I'm testing on Outlook 2003, OWA on Exchange 2003, Outlook 2007, and 
Office 365 webmail.

I can provide the emails I'm sending as attachments so you can see the 
headers if that helps, let me know.
