Till now I only psoted stuff I already figured out. Now it's time for something I don't know, yet. In current Outlook versions appointments may have some attribute called "label" (or "Beschriftung" in German) which defines the color of the entry in the list. Now the big question for me is: How may I get all appointments having a specific label? While searching around I
found out you have to use the CDOEX API to access that field for doing that using VBA but I couldn't find the correkt C# API, yet. And even if that works: I still have to load all appointments and filter them myself. I'd prefer if Outlook or Exchange would do that directly, like by using the
AdvancedSearch mechanism. Any pointers?
