code登录到Exchange Webservice去取邮件 错误： The Autodiscover service couldn't be located

在我自己的机器上（windows 2008）可以成功，但是其他的机器不行，不知道什么原因

代码是
ServicePointManager.ServerCertificateValidationCallback = CertificateValidationCallBack;
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);

service.Credentials = new NetworkCredential("s-AOATest", password_Email, "sea");
service.AutodiscoverUrl("[e-mail]", RedirectionUrlValidationCallback);

错误异常是：
Microsoft.Exchange.WebServices.Data.AutodiscoverLocalException: The Autodiscover service couldn't be located.
