we're writing an applicatiopn that is reading Appointments out of the
GroupWise Mailbox via the GroupWise Object API per C#. We now stumbled
over one problem: When an appointment sent to a given Mailbox is moved
by the Sender of the Appointment, which is not the Mailbox read by us,
then the MessageID and the CommonMessageID of the moved version of the
appointment are not equal to the original version of the appointment.

Our question is: Is there a way to determine if an appointment is the
changed version of another appointment that had been read earlier or a
completely new appointment?

Thanks for your time.

Best regards, Martin Schmidt.
