由EWS管理:获取必需的和可选的约会参与者 [英] EWS-managed: Fetch required and optional attendees of appointments

问题描述

就我现在而言，我知道如何从交换服务器BUT中获取约会，但是只要我想查看必需和可选的参与者，这些字段为空...我检查了约会三项，并且有一个与会者，除了我.我是否必须对Outlook进行不同的配置，或者我错过了什么?

As far as I am now, I know how to fetch appointments from exchange server, BUT as soon as I want to see the required and optional attendees, these fields are empty ... I checked the appointment trice and there is an attendee, except me. Do I have to config Outlook differently or do I miss something?

            List<Appointment> listOfAppointments = new List<Appointment>();

        CalendarFolder cfolder = CalendarFolder.Bind(MyService, WellKnownFolderName.Calendar);
        CalendarView cview = new CalendarView(from.ToUniversalTime(), to.ToUniversalTime());
        cview.PropertySet = new PropertySet(ItemSchema.Subject);
        cview.PropertySet.Add(AppointmentSchema.Start);
        cview.PropertySet.Add(AppointmentSchema.End);
        cview.PropertySet.Add(AppointmentSchema.Location);
        cview.PropertySet.Add(AppointmentSchema.ICalUid);
        cview.PropertySet.Add(AppointmentSchema.Organizer);
        cview.PropertySet.Add(AppointmentSchema.IsAllDayEvent);
        cview.PropertySet.Add(AppointmentSchema.DateTimeCreated);

        FindItemsResults<Appointment> result = cfolder.FindAppointments(cview);

这就是我如何获取约会的方式，正如我从异常，过失和错误中发现的那样，我不需要要求与会人员交流...但是也许我缺少了一些东西.

thats how I fetch the appointments, as I figured from exceptions and trail and error, I don't need to ask exchange for attendees... but maybe I am missing something.

推荐答案

FindAppointments操作不会返回会议的出席者.而是，指定PropertySet.IdOnly的属性集以仅获取项目的ID.然后，使用ExchangeService.LoadPropertiesForItems批量加载所需的属性.

The FindAppointments operation do not return the attendees of meetings. Instead, specify a propertyset of PropertySet.IdOnly to get only the ids of the items. Then, use the ExchangeService.LoadPropertiesForItems to perform a batch load of the properties you need.
