    node-ews

    A simple JSON wrapper for the Exchange Web Services (EWS) SOAP API
    npm install node-ews
    

    Updates in 3.4.0 (new)

    • Use ntlm-client to enable NTLMv2

    Updates in 3.2.0 (new)

    • Reverted back to official soap library to address workaround in issue #17
    • Added Notifications from PR #50 (See example 5)
    • Code cleanup

    About

    A extension of node-soap with ntlm-client to make queries to Microsoft's Exchange Web Service API work. Utilize node-soap for json to xml query processing and returns responses as json objects.

    Features:
    • Supports NTLMv1, NTLMv2, Basic, or Bearer Authentication.
    • Connects to configured EWS Host and downloads it's WSDL file so it might be concluded that this is "fairly" version agnostic
    • After downloading the WSDL file, the wrapper dynamically exposes all EWS SOAP functions
    • Attempts to standardize Microsoft's WSDL by modifying the file to include missing service name, port, and bindings
    • This DOES NOT work with anything Microsoft Documents as using the EWS Managed API.
    • When using NTLMv2 you have to you your Windows username and not your email address

    https://msdn.microsoft.com/en-us/library/office/aa566468
    const EWS = require('node-ews');
    
    // exchange server connection info
    const ewsConfig = {

          "Body" : {
            "attributes": {
              "BodyType" : "Text"
            },
            "$value": "This is a test email"
          },
          "ToRecipients" : {
            "Mailbox" : {
              "EmailAddress" : "someone@gmail.com"
            }
          },
          "IsRead": "false"
        }
      }
    };
    
    // query ews, print resulting JSON to console
    ews.run(ewsFunction, ewsArgs)
      .then(result => {
        console.log(JSON.stringify(result));
      })
      .catch(err => {
        console.log(err.stack);
      });

    Example 5: Creating a Push Notification Service Listener

    // specify listener service options
    const serviceOptions = {
      port: 8080, // defaults to port 8000
      path: '/', // defaults to '/notification'
      // If you do not have NotificationService.wsdl it can be found via a quick Google search
      xml:fs.readFileSync('NotificationService.wsdl', 'utf8') // the xml field is required
    };
    
    // create the listener service
    ews.notificationService(serviceOptions, function(response) {
      console.log(new Date().toISOString(), '| Received EWS Push Notification');
      console.log(new Date().toISOString(), '| Response:', JSON.stringify(response));
      // Do something with response
      return {SendNotificationResult: { SubscriptionStatus: 'OK' } }; // respond with 'OK' to keep subscription alive
      // return {SendNotificationResult: { SubscriptionStatus: 'UNSUBSCRIBE' } }; // respond with 'UNSUBSCRIBE' to unsubscribe
    });
    
    // The soap.listen object is passed through the promise so you can optionally use the .log() functionality
    // https://github.com/vpulim/node-soap#server-logging
    .then(server => {
      server.log = function(type, data) {
        console.log(new Date().toISOString(), '| ', type, ':', data);
      };
    });
    
    // create a push notification subscription
    // https://msdn.microsoft.com/en-us/library/office/aa566188
    const ewsConfig = {
      PushSubscriptionRequest: {
        FolderIds: {
          DistinguishedFolderId: {
            attributes: {
              Id: 'inbox'
            }
          }
        },
        EventTypes: {
          EventType: ['CreatedEvent']
        },
        StatusFrequency: 1,
        // subscription notifications will be sent to our listener service
        URL: 'http://' + require('os').hostname() + ':' + serviceOptions.port + serviceOptions.path
      }
    };
    ews.run('Subscribe', ewsConfig);

    Office 365

    Below is a template that works with Office 365.

    const EWS = require('node-ews');
    
    // exchange server connection info
    const ewsConfig = {
      username: 'myuser@domain.com',
      password: 'mypassword',
      host: 'https://outlook.office365.com',
      auth: 'basic'
    };
    
    // initialize node-ews
    const ews = new EWS(ewsConfig);
    
    // define ews api function
    const ewsFunction = 'ExpandDL';
    
    // define ews api function args
    const ewsArgs = {
      'Mailbox': {
        'EmailAddress':'publiclist@domain.com'
      }
    };
    
    // query EWS and print resulting JSON to console
    ews.run(ewsFunction, ewsArgs)
      .then(result => {
        console.log(JSON.stringify(result));
      })
      .catch(err => {
        console.log(err.message);
      });

    Advanced Options

    Adding Optional Soap Headers

    To add an optional soap header to the Exchange Web Services request, you can pass an optional 3rd variable to the ews.run() function as demonstrated by the following:

    const EWS = require('node-ews');
    
    // exchange server connection info
    const ewsConfig = {
      username: 'myuser@domain.com',
      password: 'mypassword',
      host: 'https://ews.domain.com'
    };
    
    // initialize node-ews
    const ews = new EWS(ewsConfig);
    
    // define ews api function
    const ewsFunction = 'GetUserOofSettings';
    
    // define ews api function args
    const ewsArgs = {
      'Mailbox': {
        'Address':'email@somedomain.com'
      }
    };
    
    // define custom soap header
    const ewsSoapHeader = {
      't:RequestServerVersion': {
        attributes: {
          Version: "Exchange2013"
        }
      }
    };
    
    // query ews, print resulting JSON to console
    ews.run(ewsFunction, ewsArgs, ewsSoapHeader)
      .then(result => {
        console.log(JSON.stringify(result));
      })
      .catch(err => {
        console.log(err.stack);
      });

    Enable Basic Auth instead of NTLM:

    // exchange server connection info
    const ewsConfig = {
      username: 'myuser@domain.com',
      password: 'mypassword',
      host: 'https://ews.domain.com',
      auth: 'basic'
    };
    
    // initialize node-ews
    const ews = new EWS(ewsConfig);

    Enable Bearer Auth instead of NTLM:

    // exchange server connection info
    const ewsConfig = {
      username: 'myuser@domain.com',
      token: 'oauth_token...',
      host: 'https://ews.domain.com',
      auth: 'bearer'
    };
    
    // initialize node-ews
    const ews = new EWS(ewsConfig);

    Disable SSL verification:

    To disable SSL authentication modify the above examples with the following:

    Basic and Bearer Auth

    const options = {
     rejectUnauthorized: false,
     strictSSL: false
    };
    process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';
    
    const ews = new EWS(config, options);

    NTLM

    const options = {
     strictSSL: false
    };
    process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';
    
    const ews = new EWS(config, options);

    Specify Temp Directory:

    By default, node-ews creates a temp directory to store the xsd and wsdl file retrieved from the Exchange Web Service Server.

    To override this behavior and use a persistent folder add the following to your config object.

    // exchange server connection info
    const ewsConfig = {
      username: 'myuser@domain.com',
      password: 'mypassword',
      host: 'https://ews.domain.com',
      temp: '/path/to/temp/folder'
    };
    
    // initialize node-ews
    const ews = new EWS(ewsConfig);

    Constructing the ewsArgs JSON Object

    Take the example of "FindItem" that is referenced in the Microsoft EWS API Docs as follows:

    <?xml version="1.0" encoding="utf-8"?>
    <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
                   xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types">
      <soap:Body>
        <FindItem xmlns="http://schemas.microsoft.com/exchange/services/2006/messages"
                   xmlns:t="http://schemas.microsoft.com/exchange/services/2006/types"
                  Traversal="Shallow">
          <ItemShape>
            <t:BaseShape>IdOnly</t:BaseShape>
          </ItemShape>
          <ParentFolderIds>
            <t:DistinguishedFolderId Id="deleteditems"/>
          </ParentFolderIds>
        </FindItem>
      </soap:Body>
    </soap:Envelope>

    The equivalent JSON Request for node-ews (ewsArgs) would be:

    {
      'attributes': {
        'Traversal': 'Shallow'
      },
      'ItemShape': {
        'BaseShape': 'IdOnly'
      },
      'ParentFolderIds' : {
        'DistinguishedFolderId': {
          'attributes': {
            'Id': 'deleteditems'
          }
        }
      }
    }

    It is important to note the structure of the request. Items such as "BaseShape" are children of their parent element. In this case it is "ItemShape". In regards "BaseShape" it is enclosed between an opening and closing tag so it is defined as a direct clid of "ItemShape".

    However, "DistinguishedFolderId" has no closing tag and you must specify an ID. Rather than a direct child object, you must use the JSON child object "attributes".
