We are using the WebService to create appointments and tasks for the Microsoft Exchange Server 2007.
We need to read the field "billinginformation" from calendar items.
To insert and read a task with this field is no problem. The insert of a new calendar item with the billinginformation is also no problem, but we can not find the right syntax to read the billing information from an existing calendar item.
Can everybody help us? We are using C#. We take PropertyID 34101  and propertyTag 0x8535
Thanks a lot!

This worked for me. Of course it came from Outlook, but should be simular I would imagine.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Outlook = Microsoft.Office.Interop.Outlook;
namespace OutlookAppt
    class Program
        static void Main(string[] args)
            Outlook.Application app = new Microsoft.Office.Interop.Outlook.Application();
            Outlook._NameSpace nameSpace = app.GetNamespace("MAPI");
            nameSpace.Logon(null, null, false, false);
            Outlook.MAPIFolder calendar = nameSpace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderCalendar);
            foreach (Outlook.AppointmentItem appt in calendar.Items)
