Отправить письмо через microsoft exchange Сервер api (java)

Question

Я хочу отправить электронное письмо с API-интерфейсом Java и Microsoft Exchange. Я выполнил инструкцию из документов, но всегда получаю исключение.

Все параметры (имя пользователя, пароль, домен и uri указаны правильно). Я тестировал этот параметр с помощью редактора EWS от Microsoft, а с редактором я получаю соединение.

Мой код заключается в следующем:

import microsoft.exchange.webservices.data.EmailMessage; 
import microsoft.exchange.webservices.data.ExchangeCredentials; 
import microsoft.exchange.webservices.data.ExchangeService; 
import microsoft.exchange.webservices.data.ExchangeVersion; 
import microsoft.exchange.webservices.data.MessageBody; 
import microsoft.exchange.webservices.data.WebCredentials; 

public class Mail { 

ExchangeService service = new ExchangeService(
     ExchangeVersion.Exchange2010_SP2); 

ExchangeCredentials credentials = new WebCredentials("user", 
     "passwort", "domain"); 

public void sendMail() throws Exception { 

    service.setTraceEnabled(true); 
    java.net.URI uri = new java.net.URI(
      "https://********/ews/exchange.asmx"); 

    service.setCredentials(credentials); 
    service.setUrl(uri); 

    System.out.println(service.getServerInfo()); 

    EmailMessage msg = new EmailMessage(service); 
    msg.setBody(MessageBody 
      .getMessageBodyFromText("Sent using the EWS Managed API.")); 
    msg.getToRecipients().add("send mail to "); 
    msg.send(); 
} 

public static void main(String[] args) throws Exception { 
    Mail mail = new Mail(); 
    mail.sendMail(); 
} 

Исключение заключается в следующем:

Изменить

ExchangeCredentials credentials = new WebCredentials("user", "password", "domain"); 

в

service.Credentials = new NetworkCredential("user", "password", "domain");
