Autodiscover url giving error

[alkasain]

Hi Gautam,

I have to autodiscover exchange url so using below code and getting nothing in response:

code used:
var autod = new ews.AutodiscoverService(ews.ExchangeVersion.Exchange2010);

when I use hardcoded url then its working fine:

var autod = new ews.AutodiscoverService(new ews.Uri("https://autodiscover-s.outlook.com/autodiscover/autodiscover.svc"), ews.ExchangeVersion.Exchange2010);

Any help would be highly appreciated.

you have to set <AutodiscoverService>.RedirectionUrlValidationCallback for this. by default Autodiscover prevents redirection, you can override by setting this delegate.

do this right after creating AutodiscoverService instance.

autod.RedirectionUrlValidationCallback = function (url){
//validate if redirection is valid and not malicious, you can also just check for https:// 
// url parameter is a string. 
if(valid(url)){
    return true;
}
    return false;
}

above fix was for error with message: Autodiscover redirection is blocked for url: https://autodiscover-s.outlook.com/autodiscover/autodiscover.svc

let me know if you faced any other issues

I am already setting this like below:
autod.CallRedirectionUrlValidationCallback = function() {
return true;
}

but response is undefined.
from the logs I find that its failing at : Trying to get Autodiscover redirection URL from http://autodiscover.xxxx.com/autodiscover/autodiscover.xml and giving resperr.status === 0.

Which domain you are trying? Can you send me full log (after stripping 'Authorization' header) to my contact email address.

Is autodiscover.domain.com for your domain published on dns? Please send me your domain name on my email as well.

one quick query - does this module works for on-premise exchange??
As for one domain its working and for another domain(on-premise) its not working.

[gautamsi]

Yes it does, if you know exchange server url you simply use it. If you want autodiscover to work, you need autodiscover dns records. SRV records do npt work yet. Only autodiscover.domain.com cname would work. On premises exchange usually skips inter dns cname record and use SRV records.

I am sending you an email on your gmail id for domain and logs.

not really had time to test this one. can you try ews-javascript-api@next package (dev build) and report any new error? have fixed few things but could not test this one.
