using Microsoft.Exchange.WebServices.Data;

static void GetUsersEwsUrl(string userEmailAddress, SecureString userPassword) { ExchangeService service = new ExchangeService();

// Set specific credentials.
service.Credentials = new NetworkCredential(userEmailAddress, userPassword);

// Look up the user's EWS endpoint by using Autodiscover.
service.AutodiscoverUrl(userEmailAddress);

Console.WriteLine("EWS Endpoint: {0}", service.Url);

}

Remarks

If an Autodiscover server returns a redirect HTTP status code, this method will generate an AutodiscoverLocalException with the Message property set to a string such as "Autodiscover blocked a potentially insecure redirection to https://autodiscover.contoso.com/autodiscover/autodiscover.xml. To allow Autodiscover to follow the redirection, use the AutodiscoverUrl(string, AutodiscoverRedirectionUrlValidationCallback) overload." This exception is generated for all redirect responses, regardless of the validity of the URL returned in the redirect response.

To enable redirection, use the AutodiscoverUrl(String, AutodiscoverRedirectionUrlValidationCallback) overload instead.
