No, that's not possible.

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 ?
