无法找到自动发现服务。我的代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Net.Mail;
using System.Net;
using Microsoft.Exchange.WebServices.Data;
using Microsoft.Exchange.WebServices.Autodiscover;
using System.Net.Security;
using System.Security.Cryptography.X509Certificates;

namespace test
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                // Connect to Exchange Web Services as user1 at contoso.com.
                ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
                service.Credentials = new WebCredentials("[email protected]", "mypassword", "xxxx.com");
                service.TraceEnabled = true;
                service.AutodiscoverUrl("[email protected]");

                // Create the e-mail message, set its properties, and send it to [email protected], saving a copy to the Sent Items folder. 
                EmailMessage message = new EmailMessage(service);
                message.Subject = "Interesting";
                message.Body = "The proposition has been considered.";
                message.ToRecipients.Add("[email protected]");
                message.SendAndSaveCopy();

                // Write confirmation message to console window.

                Console.ReadLine();
            }
            catch (Exception ex)
            {
                Console.WriteLine("Error: " + ex.Message);
                Console.ReadLine();

I know this is an old question, but recently wrestled with this and similar looking error (including ISA server). It was fixed with:

我知道这是一个老问题，但最近遇到了这个和类似的错误（包括 ISA 服务器）。它是固定的：

service.EnableScpLookup = false;

This was not required when working with an explicit URL, but was when using AutoDiscover

这在使用显式 URL 时不是必需的，但在使用 AutoDiscover 时是必需的

The code suggest that you have an Exchange 2007 server... Is it properly configured for using the Autodiscover features? Confirm that you can ping autodiscover.XXXX.com and view https://autodiscover.XXXX.comin a web browser.

该代码表明您有一台 Exchange 2007 服务器...它是否正确配置为使用自动发现功能？确认您可以 ping autodiscover.XXXX.com 并在 Web 浏览器中查看https://autodiscover.XXXX.com。

Alternately, you may need to use your internal domain name for autodiscovery and login. For example, in my office the external email addresses are on a domain like CompanyX.com, but the internal Active Directory domain is like CompanyX.local, and we do not have autodiscover on the open Internet, so my EWS needs to locate Autodiscover.CompanyX.local.

或者，您可能需要使用内部域名进行自动发现和登录。例如，在我的办公室的外部电子邮件地址是像一个域名CompanyX.com，但内部Active Directory域是喜欢CompanyX.local，而且我们没有自动发现在开放的互联网上，所以我的EWS需求来定位Autodiscover.CompanyX.local。

This is a common problem , Autodiscover service error is encountered when this autodiscover service by exchange is down

这是一个常见的问题，当这个自动发现服务被交换器关闭时，会遇到自动发现服务错误。

Resolution is to provide actual URL for exchange location , rather than autodiscovering it.

解决方案是为交换位置提供实际 URL，而不是自动发现它。

This solved my same issue.

这解决了我同样的问题。

try these concept:

试试这些概念：

private static ExchangeService getService(String userEmail, String login, String password, String hostName)
{
    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010); 
    AutodiscoverService auservice = new AutodiscoverService(hostName);
    if (auservice.ServerInfo != null) 
    {
        try
        {
            service.AutodiscoverUrl(userEmail, RedirectionUrlValidationCallback);
        }
        catch (AutodiscoverRemoteException ex)
        {
            Console.WriteLine("Exception thrown: " + ex.Error.Message);
        }

    }
    else
    {
        service.Url = new Uri("https://" + hostName + "/EWS/Exchange.asmx");
    }

    service.UseDefaultCredentials = true;


    if (service.ServerInfo == null)
    {
        service.Credentials = new WebCredentials(login, password);
    }
    return service;
}
