Recurring Appointment Colours

[gdk]

In my c# .NET application, I am using categories colour to distinguish
between appointment items. I want to have one colour for completed recurring
appointments and one colour for uncompleted recurring appointments.

I have tried both the outlook object model and redemption and get error
"cannot change categories for single instance of a recurring meeting"

Is this possible ?

No, not possible as the message indicates. Not with recurring appointments.

Outlook 2003 has label colours which work on single incurrence of a recurring
meeting How do I set label colours in outllook using redemption or MAPI ?

You would get that instance using the GetOccurrence() method of the
RecurrencePattern and using Redemption would use the DASL property tag
"http://schemas.microsoft.com/mapi/id/{00062002-0000-0000-C000-000000000046}/82140003"
(not a URL).

In MAPI terms that would be GUID ==
"{00062002-0000-0000-C000-000000000046}", ID == 0x8214 and type == PT_LONG.
