Hi all, got "Service doesn't allow a cross domain request from this origin".
The origin is correctly whitelisted when run Get-CsWebServiceConfiguration|selectCrossDomainAuthorizationList :
{Url=https://w15-ts.contoso.com, Url=http://localhost, Url=https://W15-TS.contoso.com, Url=https://dummy.com}
Fiddler also :
X-Ms-Origin:https://w15-ts.contoso.com
Accept: application/json
X-Requested-With: XMLHttpRequest
Referer:https://lyncdiscover.contoso.com/xframe
Accept-Language: en-US
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)

Thanks in advance for any help.
