C#, Redemption, not able to set appointment color in Outlook 2003

[Johan Machielse]

Dear reader,

I use the following piece of code to change the color of an appointment in
the calendar (appointment is of type Outlook.AppointmentItem). It does not
seem to work??? Any ideas what I am doing wrong?

Rdo.SafeAppointmentItem safe = new Rdo.SafeAppointmentItem();
safe.Item = appointment;
int propertyID = safe.GetIDsFromNames(
"{00062002-0000-0000-C000-000000000046}", 0x8214 );
propertyID = propertyID | 0x3;
safe.set_Fields( propertyID, color );
appointment.Save();

Thank you in advance!

Regards,

Outlook doesn't know anything about changes you make to an item using
Extended MAPI (Redemption), so when you save the appointment your changes
are being ignored or overwritten.

Try this and see if it works better:

Rdo.SafeAppointmentItem safe = new Rdo.SafeAppointmentItem();
safe.Item = appointment;
int propertyID = safe.GetIDsFromNames(
"{00062002-0000-0000-C000-000000000046}", 0x8214 );
propertyID = propertyID | 0x3;
safe.set_Fields( propertyID, color );

appointment.Subject = appointment.Subject; // new code line

appointment.Save();
