EWS throw an exception in Autodiscover method

I am trying to connect with email box by EWS. And after that line:

 service1.AutodiscoverUrl(emailAdress);

this code throw error

Message = "The Autodiscover service returned an error"

InnerException = " "

TargetSite = "Boolean TryLastChanceHostRedirection[TSettings] (System.String, System.Uri, TSettings ByRef)"

HelpLink = ""

This code is working for another email box on other domain.

I think that something is wrong with Exchange serwer.

The Autodiscover service is providing a redirection. Try adding this callback as the second argument in the Autodiscover URL method:

static bool RedirectionCallback(string url)
{
    // Return true if the URL is an HTTPS URL.
    return url.ToLower().StartsWith("https://");
}
