Hi,

I am trying to connect to skype for busines online with azure ad.

var href = 'https://login.microsoftonline.com/common/oauth2/authorize?response_type=token&client_id=';
href += client_id + '&resource=https://webdir.online.lync.com&redirect_uri=' + "http://localhost";
window.location.href = href;

And i am entering my acoount. I am getting access_token.

Then i am doing Skype.initialize with "apiKey: config.apiKeyCC".

Everything is ok here.

Then step is signin.

var params =
    {
     "client_id": config.clientid,
     "origins": ["https://webdir.online.lync.com/autodiscover/autodiscoverservice.svc/root"],
     "cors": true,
     "version": config.appName+'/1.0.0',
     "redirect_uri": "/empty.html"
    };

    client.signInManager.signIn(params).then(function(){
      document.getElementById('SigninStatus').innerHTML = 'Signed in as ' + client.personsAndGroupsManager.mePerson.displayName();
    },function(error){
      console.log(error);
    });
