c# - Attendee.ResponseType 未知 - Exchange 托管 API

Question

我在尝试获取作为预约所需参加者的房间的 ResponseType 时遇到问题。我可以确认我的 exchange 2010 sp2 ru4 服务器立即批准或拒绝 session ，但是当我以编程方式使用 ExchangeManaged api 查找约会时，相关的所需与会者总是返回 ResponseType 的“未知”值。

这是我的代码...

 public bool IsAppointmentVerifiedWithResource(Patron userSessionObj, Reservation reservation)
    {
        var emailConfig = new DataStoreManager.ConfigurationManager();
        var serviceBinding = emailConfig.GetConfiguration(Configuration.GetConfigurationName(Resource_ConfigurationConstants.ExchangeServiceBinding));

        // Create the binding.
        var service = new ExchangeService(ExchangeVersion.Exchange2010_SP2)
        {
            UseDefaultCredentials = true,
            Url = new Uri(serviceBinding)
        };

        // Set the calendar view to use
        var view = new CalendarView(reservation.Start, reservation.End);

        // Get the target folder ID using the email address
        var folder = new FolderId(WellKnownFolderName.Calendar, new Mailbox(reservation.EmailAddress));

        view.PropertySet = new PropertySet(BasePropertySet.FirstClassProperties);

        if (CheckForApptCount(service, folder, view))
        {
            var response = service.FindAppointments(folder, view);

            service.LoadPropertiesForItems(from Item item in response select item, BasePropertySet.FirstClassProperties);

            foreach (Appointment apt in response.Items)
            {
                foreach(Attendee at in apt.RequiredAttendees)
                {
                    //room mailbox matches required attendee
                    if(at.Address == reservation.EmailAddress)
                    {
                        ******at.ResponseType always = Unknown******
                        if(at.ResponseType == MeetingResponseType.Accept)
                        {
                            return true;
                        }
                    }
                }
            }

        }

        return false;

    }

关于如何同步和加载 ResponseType 属性有什么想法吗？

谢谢，克里斯

                return foundAppointments;
            }

找到的解决方案:与会者的 ResponseType 始终为空，因为我正在为与会者的邮箱执行“findappointments”，然后尝试获取该与会者的 ResponseType。获取与会者 ResponseType 的正确方法是为组织者的邮箱运行“findappointments”。找到约会后，枚举与会者，ResponseType 将可用。
