Hello, I try to create an exception of a recurring appointment using WebDAV. I can create recurring Appointments, but when I try to create an exception the recurring appointment is displayed as a non recurring appointment in Outlook 2003. Everything is fine with recurring appointments created by Outlook. All exceptions are displayed correctly, but if i want create an exception of the recurring appointment by my code the first instance of the appointment is only displayed as a non recurring appointment. Other instances are missing... Please help. Thank you. R.
