Write office plugin to add new fields to the meeting request

Question

Is there a way to write an office plugin to add new fields to the New Meeting Request section in Outlook? for example, I want to add a new field for Agenda...

Is this doable?

Answer 1

It is doable:
For this purpose you should add User Property to your Outlook.MeetingItem:

 Outlook.MeetingItem item = //get or create your item here;
 if(item.UserProperties["Agenda"] == null){
     Outlook.UserProperty property = item.UserProperties.Add("Agenda", olText);
 }
 property.value = "Your agenda"; 
 item.Save();

This code will add Agenda property to your meeting item.

Now if you want to display it you should go with Custom View or Custom TaskPane or Form Region
