WebDAV - How to update organizer appt when sending meeting update   

Hello,

I have been successful in updating meeting requests and everything works 
fine on the recipient end.  But the appointment in the meeting organizer's 
calendar is never updated.  Should I be using a different method call in the 
calendar region?  Is there another way to do this?

I've posted the code.

Thanks!
