Question

我正在使用以下代码从日历中返回项目。当我连接用户的实际凭据时，我会按预期返回10个项目。当我作为服务帐户连接时，我总是得到0.服务帐户具有查看和更新用户日历的权限。为什么不回复任何结果？

            // Connect to Exchange Web Services
            service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);

            --> service.Credentials = new WebCredentials("svc_user", "svc_password", "domain");
            --> //service.Credentials = new WebCredentials("user", "password", "domain");
            service.AutodiscoverUrl("user@domain");

            //Return count
            ItemView view = new ItemView(10);
            view.PropertySet = new PropertySet(BasePropertySet.IdOnly);
            FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Calendar, view);
            MessageBox.Show(findResults.Count().ToString());

我必须为服务提供ImpersonatedUserId的价值：

        // Connect to Exchange Web Services
        service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);

        service.Credentials = new WebCredentials("svc_user", "svc_password", "domain");
        service.AutodiscoverUrl("user@domain");
        service.ImpersonatedUserId = new ImpersonatedUserID(ConnectingIdType.SmtpAddres, "user@domain");

        //Return count
        ItemView view = new ItemView(10);
        view.PropertySet = new PropertySet(BasePropertySet.IdOnly);
        FindItemsResults<Item> findResults = service.FindItems(WellKnownFolderName.Calendar, view);
        MessageBox.Show(findResults.Count().ToString());

我的假设是，通过在用户的商店上运行自动发现，默认情况下会进行模拟。
