从exchange读取邮件的Javamail在本地主机中工作,但在服务器上托管时不工作

当我从本地主机尝试时,我能够成功地使用javamail读取和删除邮件,但当我在服务器上部署java代码并尝试调用服务时,它会在store.connect(pop3Host,user,password)处卡住;

Here are the properties added:

    Properties properties = new Properties();
                properties.put("mail.store.protocol", "pop3");
            //  properties.put("mail.imap.host", pop3Host);
            //  properties.put("mail.imap.port", 143);
            //  properties.put("mail.smtp.auth.plain.disable", true);
                properties.put("mail.pop3.starttls.enable", "true");
                properties.setProperty("ssl.SocketFactory.provider", "ExchangeSSLSocketFactory");
                properties.setProperty("mail.pop3.socketFactory.class", "ExchangeSSLSocketFactory");
                Session emailSession = Session.getInstance(properties);
                 emailSession.setDebug(true);
                // create the POP3 store object and connect with the popserver
                Store store = emailSession.getStore("pop3s");
                store.connect(pop3Host, user, password);

                // create the folder object and open it
                Folder emailFolder = store.getFolder("INBOX");
                emailFolder.open(Folder.READ_WRITE);
