EWS - 代表访问

Question

我正在尝试使用 EWS 访问其他人的日历。我可以正常访问自己的日历：

    foreach (Appointment appointment in service.FindItems(
        WellKnownFolderName.Calendar, new ItemView(int.MaxValue)))
    {
        Console.WriteLine(appointment.Subject);
    }
}

但是，当我尝试模拟时（即使使用委托访问），我在下面的代码中遇到未处理的异常错误（抱歉，它是完整的代码，但我认为它可能会有所帮助！）问题孩子似乎在 foreach循环

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Microsoft.Exchange.WebServices.Data;
using Test.ExchangeServices;
 using System.Net;

namespace Test
{
class Program
{
    static void Main(string[] args)
    {
 // Connect to Exchange Web Services
    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1);

    service.Credentials = new WebCredentials("User", "Pass", "Domain");
    service.Url = new Uri("https://EWS/EWS/Exchange.asmx");

    //Impersonate the user who is creating the appiontment request (doesn't work so commented out)
// service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, userEmail);

/Delegate access 

    foreach (Appointment appointment in service.FindItems(
new FolderId(WellKnownFolderName.Calendar, new Mailbox("otheremployee@company.com")), 
new ItemView(10)))
    {
        Console.WriteLine(appointment.Subject);
    }
}



    }
}

如果有帮助，我附上了错误截图：

您需要审阅者访问日历，然后它才会起作用。 :)
