java怎么连接exchange收发邮件

public static void main(String[] args) {
    Exchange.conn();
}



public static void conn(){
    boolean result = false;
    ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010);
    ExchangeCredentials credentials = new WebCredentials(用户名，密码，域);
    service.setCredentials(credentials);
    try {
        service.setUrl(new URI("https://192.168.1.124/EWS/Exchange.asmx"));

        Folder inbox = Folder.bind(service, WellKnownFolderName.Inbox);
        System.out.println(service.getTimeout());

    } catch (Exception e) {
        e.printStackTrace();
    }
}

总是报microsoft.exchange.webservices.data.ServiceLocalException: https://192.168.1.124/EWS/Exchange.asmx : Connection error

浏览器可以打开这个连接，但是需要输入用户密码，还有代码中的用户密码各是指什么？

崩溃中。。。。
