使用ews-javascript-api连接Exchange Server遇401错误求排查

问题概述 #

我通过NodeJS结合ews-javascript-api连接Microsoft Exchange Server时遇到认证异常：

• 凭证在微软连接测试站验证有效，但代码使用cookieAuthXhrApi时返回401 Unauthorized错误
• 切换为ntlmAuthXhrApi时，出现**"Invalid message signature: Negotiate"**错误

代码示例 #

var ews = require('ews-javascript-api');
var ewsAuth = require("ews-javascript-api-auth");

async send(params) {
  const { subject, html } = params;

  let { to } = params;

  if (process.env.APP_ENV === "development") {
    to = process.env.MAIL_TO_DEV;
  }

  const sendMail = async (to, subject, html) => {
    ews.ConfigurationApi.ConfigureXHR(new ewsAuth.cookieAuthXhrApi(`${process.env.MAIL_USERNAME}`, process.env.MAIL_PASSWORD));
    const ewsConnection = new ews.ExchangeService(ews.ExchangeVersion.Exchange2010);
   
    ewsConnection.Credentials = new ews.ExchangeCredentials(`${process.env.MAIL_USERNAME}`, process.env.MAIL_PASSWORD);
    ewsConnection.Url = new ews.Uri(`${process.env.MAIL_HOST}`);

    const emailMessage = new ews.EmailMessage(ewsConnection);
    emailMessage.Subject = subject;
    emailMessage.Body = new ews.MessageBody(ews.BodyType.HTML, html);

    emailMessage.ToRecipients.Add(to);

    try {
      await emailMessage.Send();
      console.log('Email sent successfully.');
    } catch (error) {
      console.log('Email error:', error);
    }
  };

  sendMail(to, subject, html)
  .catch((error) => console.log('Email error:', error));
   
  return {};
}

  },

MAIL_PORT=25
MAIL_USERNAME="xxxxxxxxx"
MAIL_PASSWORD="xxxx2023"
MAIL_FROM="xxxx@xxxx.com.br"
MAIL_TO_DEV="xxxxx@xxxxx.com.br"

想了解是否有适用于JavaScript的Exchange Server专用SDK，或请求提供可正常运行的JavaScript集成代码示例。
