c# - 预警系统。请求失败。远程服务器返回错误：(401) Unauthorized on Mac OS only

Question

我需要连接到 EWS。我为此使用 Microsoft.Exchange.WebServices.NETStandard NuGet 包。在 Windows 机器上一切正常，但在 Mac OS 上我收到错误“远程服务器返回错误：（401）未经授权。” 此外，如果我只使用 Microsoft.Exchange.WebServices 它可以正常工作，但我的整个项目都是基于 .Net Core。也许，有人遇到过这个问题。

using System;
using System.Linq;
using Microsoft.Exchange.WebServices.Data;

namespace testExchange
{
    class Program
    {
        static void Main(string[] args)
        {
            var exchangeService = new ExchangeService(ExchangeVersion.Exchange2010_SP2, TimeZoneInfo.Utc);
            
            string userLogin = "userLogin";
            string userPass = "userPassword";
            string exchangeDomain = "icx";
            string userEmail = "[e-mail]";
            string webmail = "https://domain/ews/Exchange.asmx";
            exchangeService.Credentials = new WebCredentials(userLogin, userPass, exchangeDomain);
            exchangeService.Url = new Uri(webmail);

            string name = exchangeService.ResolveName(userEmail, ResolveNameSearchLocation.DirectoryOnly, true).Result.First().Contact.DisplayName;

            Console.WriteLine(name);
        }
    }
}
