交易所Web服务API和401未授权异常 [英] Exchange Web Service API and 401 unauthorized exception

问题描述

当我尝试使用EWS API发送电子邮件，我得到以下错误：（在 message.Send（）; ）

When I try sending email using the EWS API, I get the following error: (in message.Send();)

请求失败。远程服务器返回错误：（401）未经授权

The request failed. The remote server returned an error: (401) Unauthorized.

我的code是以下内容：

My code is the following:

ExchangeService exchangeService = new ExchangeService(ExchangeVersion.Exchange2007_SP1);

//WebService Uri
try
{
    exchangeService.Url = new Uri("https://exchangeserver/ews/exchange.asmx");
}
catch (Exception ex)
{
    throw new Exception(string.Format("WebService Uri:" + ex));
}

//Credentials
try
{
    exchangeService.Credentials = new WebCredentials("user@domain", "pwd", "domain");
}
catch (Exception ex)
{
    throw new Exception(string.Format("Credentials:" +  ex));
}

//Send a mail
try
{
    EmailMessage message = new EmailMessage(exchangeService);
    message.Subject = "Test";
    message.Body = "Test";
    message.ToRecipients.Add("destination@domain");
    message.Save();
    message.Send();
}
catch (Exception ex)
{
    throw ex;
}

我读了这个网站有关这一问题的其他职位，但他们解决不了我的问题。

I read other posts on this site concerning this issue but they couldn't resolve my issue.

推荐答案

尝试改变这一点：

 exchangeService.Credentials = new WebCredentials("user@domain", "pwd", "domain");

这个：

 exchangeService.Credentials = new WebCredentials("user", "pwd", "domain");

有时登录凭据依赖于交换/ Active Directory的它是如何的配置。
这可能是用户@域或域\\用户

Sometime the Login credentials depends on how Exchange/Active Directory it's configured. It could be user@domain or domain\user
