IMAP access to mail office 365 with javamail

问题

I'm trying to read the emails in a folder of an email account Office365 using JavaMail 1.4 api.

My code is:

    public static void main(String argv[]) throws Exception {
    // Get a Properties object
    Properties props = System.getProperties();

    // Get a Session object
    Session session = Session.getInstance(props, null);

    // Get a Store object
    Store store = null;
    Folder rf = null;

    if (CUR_MAIL_PROTOCOL != null)
        store = session.getStore("imap");

    // Connect
    if (CUR_MAIL_HOST != null || CUR_MAIL_LOGIN != null || CUR_MAIL_PWD != null)
        store.connect("outlook.office365.com", 993, "**MYEMAIL**", "**MYPASS**");
    else
        store.connect();

    // List namespace
    rf = store.getDefaultFolder();

    getFolderDetails(rf, true, "");
    if ((rf.getType() & Folder.HOLDS_FOLDERS) != 0) {
        Folder[] f = rf.list("%");
        for (int i = 0; i < f.length; i++)
            getFolderDetails(f[i], recursive, "    ");
    }

    store.close();
}

My error is:

    Exception in thread "main" javax.mail.MessagingException: Connection timed out: connect;
  nested exception is: 
    java.net.ConnectException: Connection timed out: connect
    at com.sun.mail.imap.IMAPStore.protocolConnect(IMAPStore.java:298)
    at javax.mail.Service.connect(Service.java:234)

Thanks
