I’m using C# with Apose.Email 20.2 to handle calendar items in PST.
If an all day MapiCalendar is saved to a MSG file,
the value of property AppointmentStateFlags (KnownPropertyList.AppointmentStateFlags) will be missed in MSG file.
After saving, the value of AppointmentStateFlags in this message is not existed any more. It’s quite strange since the issue only occurred with all day events.
Could someone help me on this ?
