exchange-autodiscover

Node Exchange Autodiscover

Retrieve the URL of your EWS by accessing Microsoft's SOAP Autodiscover Service.

Differs from other similar packages in that it queries the DNS. It also tries out all the potential autodiscover urls in parallel, sacrificing a bit more bandwidth for speed.

Usage

const autodiscover = require('exchange-autodiscover');

// Promise
autodiscover({ emailAddress: "[e-mail]", password: "pass" })
  .then(console.log.bind(console))  // 'https://outlook.microsoft.com/ews/exchange.asmx'
  .catch(console.error.bind(console));

// Callback
autodiscover({
  emailAddress: "[e-mail]",
  password: "pass",
  username: "ad\\foobar77"
}, function(err, ewsUrl) {
  if (err) {
    console.error(err);
  } else {
    console.log(ewsUrl); // 'https://mail.yourdomain.com/ews/exchange.asmx'
  }
});

You can optionally request any of the extra settings found here. This will return an object with matched settings (EWS address will always be included by default).

// With extra settings
autodiscover({
  emailAddress: "[e-mail]",
  password: "pass",
  settings: [
    'EwsSupportedSchemas',
    'ExternalEwsVersion'
  ]
}).then(function (settings) {
  console.log(settings);
  // {
  //   EwsSupportedSchemas: 'Exchange2007, Exchange2007_SP1, Exchange2010, Exchange2010_SP1, Exchange2010_SP2, Exchange2013, Exchange2013_SP1, Exchange2015',
  //   ExternalEwsUrl: 'https://outlook.office365.com/EWS/Exchange.asmx',
  //   ExternalEwsVersion: '15.00.0000.000'
  // }
});
