An iCalendar (ics) email attachment fails to import into Outlook.

I have created the following CFC based on a UDF I found online somewhere.  It basically creates a .ics (iCalendar) file that is e-mailed to a client.  The event is accepted by iCal on the Mac but fails when someone with MS Outlook tries to open it.    I even added a bunch of fields that I noticed in an icalendar event sent from Outlook but it still fails.    I also added the contents of the generated ics file below...

Any suggestion?
