C# code works, but not its Node equivalent: 401 Unauthorized about ews-javascript-api HOT 16 CLOSED

Investigating further on the 'CreateItem' request sent, I could find some differences in the headers:

• The C# working version has no "Authoriszation: ' Basic ..." header (and the Node one has one), and no 'Accept' nor 'Accept-Encoding' headers
• The C# working version also has much more headers:

Any clue to make my Node app work?
Many thanks!

from ews-javascript-api.

Am I the only one have this issue? If anyone has any clue, even if it's not a solution, I would greatly appreciate any feedback: it might help me to find what to look after, to fix it.
Big thank you in advance!

Same problem here, but no solution yet...

Thanks Cimchd, I feel less alone.

Have you tried to find out if you need NTLM auth or basic auth? Check with your exchange admin. This library does not have built in Windows NTLM auth you have to use it separately

from ews-javascript-api.

Thank you Gautamsi, the C# code above works. Could it work if NTLM is required?

from ews-javascript-api.

yes, c# runs on windows and it can choose between NTLM or not, but you have to know beforehand with this lib and use https://github.com/ewsjs/xhr to setup NTLM.

from ews-javascript-api.

Thank you so much, will give a try (I have zero skills on ntlm, hope I won't be stuck due to this)

from ews-javascript-api.

Great news, thanks to the xhr package I could make it work, thank you again!

Now, I would like to use the autodiscover, but it does not work:

const ews = require("ews-javascript-api")
var ewsAuth = require("ews-javascript-api-auth");
ews.ConfigurationApi.ConfigureXHR(new ewsAuth.ntlmAuthXhrApi(user.email, user.password));

var autod = new ews.AutodiscoverService(new ews.Uri("https://autodiscovers.outlook.com/autodiscover/autodiscover.xml"), ews.ExchangeVersion.Exchange2010_SP1);
autod.Credentials = new ews.WebCredentials(user.email, user.password);
var settings = [
    ews.UserSettingName.InternalEwsUrl,
    ews.UserSettingName.ExternalEwsUrl,
    ews.UserSettingName.UserDisplayName,
    ews.UserSettingName.UserDN,
    ews.UserSettingName.EwsPartnerUrl,
    ews.UserSettingName.DocumentSharingLocations,
    ews.UserSettingName.MailboxDN,
    ews.UserSettingName.ActiveDirectoryServer,
    ews.UserSettingName.CasVersion,
    ews.UserSettingName.ExternalWebClientUrls,
    ews.UserSettingName.ExternalImap4Connections,
    ews.UserSettingName.AlternateMailboxes
];
autod.GetUserSettings([user.email], settings)
    .then(function (response) {
      //do what you want with user settings    
    }, function (e) {
      console.error("autod error", e)
    });
}

When I run this, I get: autod error undefined

I have tried some variants, but no luck. Do you know what is wrong here?
Many thanks

from ews-javascript-api.

Softly asking again in case my last question was skipped :) Many thanks again for the help provided already!

from ews-javascript-api.

Autodiscover may not work with NTLM, in case you are using NTLM you can provide direct URL to ews.

in this example, you have already provided url so it is not going to autodiscover anything

from ews-javascript-api.

Thank you very much Gautamsi! Do you refer to the code example I gave on February 3rd? The only URL it provides is one for autodiscovery (autodiscovers.outlook.com/...), so I don't understand why you say it is not going to autodiscover anything.

Regarding NTLM, autodiscovery works with the C# code I have provided on January 2nd, so I suspect the reason of failure is not NTLM, do you agree? Or do you mean that the autodiscover implementation of the ews-javascript-api node package does not work with NTLM?

One more hint: I have tried with a 3rd party tool (Calendly) that by giving only the email address and the password, it was able to connect to that specific account, so the autodiscovery has worked in that case too.

Many thanks in advance for any further help! I would love so much to offer autodiscovery in my app :)

I no longer have access to NTLM exchange server to test this :(

from ews-javascript-api.

Hi @gautamsi, I'm experiencing the same issue as @bfredo123.

I no longer have access to NTLM exchange server to test this :(

I've setup a test Exchange server following these instructions. Is there anything that the instructions are missing to enable NTLM?

That should do it, let me know how can I access this. you can connect with me on linkedin (link in profile) to send message with credential.

from ews-javascript-api.

thanks @joeauyeung for the server access,

I have updated version to 0.14 (ccd9d30) which fixes this. The fix is sourced from SamDecrock/node-http-ntlm#107

alternative solution was to use NODE_OPTIONS=--openssl-legacy-provider or the option in the node command line.
