npm install node-ewsA 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.

// subscription notifications will be sent to our listener service

};
ews.run('Subscribe', ewsConfig);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);
});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);
});
// 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);// 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);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);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);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".
