Ken,

Thanks so much! Once I read the words: "touching that property makes an
appointment recurring", I knew exactly what the problem was.

I now check IsRecurring before calling the GetRecurrancePattern method.
Everything works perfectly now.

Thanks again for your prompt, concise and accurate reply.

As I mentioned, you need to check IsRecurring before accessing
item.RecurrencePattern. Just touching that property makes an appointment
recurring. You should only access that property if IsRecurring is true.

Thanks for the reply.

Here is the entire class OutlookCalendar that I'm using. The Main Form
sets
the Delegate AppointmentsModified which re-loads all the appointments for
Today (by calling the method getCalendarDataSet) and re-displays them.

I don't think that my program is modifying anything in the event or the
recurrance pattern. Am I wrong?

Thanks again for any help.

Mark
