Could not connect to SMTP host: outlook.office365.com, port: 587; nested exception is: java.net.SocketException: Permission denied: connect

I have written code that sends email using outlook.office365.com. When I am running the program getting the following error.

nested exception is:

I think, you don't have permission for access your email. For example while i try in my gmail account, if i don't open the setting that show at below, i get a authorization failed but if i open the setting, i can send e-mail with your code.
Please check your e-mail permission and settings.

Send email through App without opening mail App in Android

so I searched a lot to send an email throught my app, but without the user having to log in in an email app and send it himself. I would like to just let him write it in an editText and then just press a button and send it to me. So that's what I did: 2 classes for the mail thing, my activity which calls it, add the 3 libraries and the internet permission. What did I do wrong?
Here is where I call the email process :
private View.OnClickListener btnMode1Listener = new
View.OnClickListener() {
#Override
public void onClick(View v) {
suggestionText = entre_suggestion.getText().toString();
Log.i("SendMailActivity", "Send Button Clicked.");
String fromEmail = "fromEmail#gmail.com";
String fromPassword = "frompassword";
String toEmails = "toEmail#gmail.com";
List toEmailList = Arrays.asList(toEmails
.split("\\s*,\\s*"));
Log.i("SendMailActivity", "To List: " + toEmailList);
String emailSubject = "Suggestion";
String emailBody = suggestionText;
new SendMailTask(suggestions.this).execute(fromEmail,
fromPassword, toEmailList, emailSubject, emailBody);
}
};
This is the first class "GMail":
public class GMail {
final String emailPort = "587";// gmail's smtp port
final String smtpAuth = "true";
final String starttls = "true";
final String emailHost = "smtp.gmail.com";
String fromEmail;
String fromPassword;
List toEmailList;
String emailSubject;
String emailBody;
Properties emailProperties;
Session mailSession;
MimeMessage emailMessage;
public GMail() {
}
public GMail(String fromEmail, String fromPassword,
List toEmailList, String emailSubject, String emailBody) {
this.fromEmail = fromEmail;
this.fromPassword = fromPassword;
this.toEmailList = toEmailList;
this.emailSubject = emailSubject;
this.emailBody = emailBody;
emailProperties = System.getProperties();
emailProperties.put("mail.smtp.port", emailPort);
emailProperties.put("mail.smtp.auth", smtpAuth);
emailProperties.put("mail.smtp.starttls.enable", starttls);
Log.i("GMail", "Mail server properties set.");
}
public MimeMessage createEmailMessage() throws AddressException,
MessagingException, UnsupportedEncodingException {
mailSession = Session.getDefaultInstance(emailProperties, null);
emailMessage = new MimeMessage(mailSession);
emailMessage.setFrom(new InternetAddress(fromEmail, fromEmail));
for (Object toEmail : toEmailList) {
Log.i("GMail","toEmail: "+toEmail);
emailMessage.addRecipient(Message.RecipientType.TO,
new InternetAddress((String) toEmail));
}
emailMessage.setSubject(emailSubject);
emailMessage.setContent(emailBody, "text/html");// for a html email
// emailMessage.setText(emailBody);// for a text email
Log.i("GMail", "Email Message created.");
return emailMessage;
}
public void sendEmail() throws AddressException, MessagingException {
Transport transport = mailSession.getTransport("smtp");
transport.connect(emailHost, fromEmail, fromPassword);
Log.i("GMail","allrecipients: "+emailMessage.getAllRecipients());
transport.sendMessage(emailMessage, emailMessage.getAllRecipients());
transport.close();
Log.i("GMail", "Email sent successfully.");
}
}
And this is the second class "SendMailtask":
public class SendMailTask extends AsyncTask {
private ProgressDialog statusDialog;
private Activity sendMailActivity;
public SendMailTask(Activity activity) {
sendMailActivity = activity;
}
protected void onPreExecute() {
statusDialog = new ProgressDialog(sendMailActivity);
statusDialog.setMessage("Getting ready...");
statusDialog.setIndeterminate(false);
statusDialog.setCancelable(false);
statusDialog.show();
}
#Override
protected Object doInBackground(Object... args) {
try {
Log.i("SendMailTask", "About to instantiate GMail...");
publishProgress("Processing input....");
GMail androidEmail = new GMail(args[0].toString(),
args[1].toString(), (List) args[2], args[3].toString(),
args[4].toString());
publishProgress("Preparing mail message....");
androidEmail.createEmailMessage();
publishProgress("Sending email....");
androidEmail.sendEmail();
publishProgress("Email Sent.");
Log.i("SendMailTask", "Mail Sent.");
} catch (Exception e) {
publishProgress(e.getMessage());
Log.e("SendMailTask", e.getMessage(), e);
}
return null;
}
#Override
public void onProgressUpdate(Object... values) {
statusDialog.setMessage(values[0].toString());
}
#Override
public void onPostExecute(Object result) {
statusDialog.dismiss();
}
}
And finally, the 3 librairies I added:
compile files('libs/activation.jar')
compile files('libs/additionnal.jar')
compile files('libs/mail.jar')
So yeah, I searched a lot and didn't find how to debug it. I tried a lot of different ways but it never sent the email. I just want to be clear that I don't want to open the mail app, I want the email to be sent without the user having to do something.

Here is my Utility class code:

Properties properties = new Properties();

// creates a new session with an authenticator
Authenticator auth = new Authenticator() {

}
};
Session session = Session.getInstance(properties, auth);
// creates a new e-mail message
Message msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(userName));
InternetAddress[] toAddresses = { new InternetAddress(toAddress) };
msg.setRecipients(Message.RecipientType.TO, toAddresses);
msg.setSubject(subject);
msg.setSentDate(new Date());
msg.setText(message);
// sends the e-mail
Transport.send(msg);
}
}

add this block in your Class EmailUtility
BodyPart messageBodyPart = new MimeBodyPart();
Multipart multipart = new MimeMultipart();
try {
messageBodyPart.setContent(message, "text/html; charset=utf-8");
//messageBodyPart.setText(MessageContent);
multipart.addBodyPart(messageBodyPart);
} catch (MessagingException e) {
e.printStackTrace();
}
then replace
msg.setText(message);
with
// creates a new e-mail message
Message msg = new MimeMessage(session);
msg.setContent(multipart);

Here is the code snippet to send email.
try {
String host = "yourHostName";
String from = "test#test.com";
String to[] = {"test123#test123.com"};
String subject = "Test";
String message = "Test";
Properties prop = System.getProperties();
prop.put("mail.smtp.host", host);
Session sess1 = Session.getInstance(prop, null);
MimeMessage msg = new MimeMessage(sess1);
msg.setFrom(new InternetAddress(from));
InternetAddress[] toAddress = new InternetAddress[to.length];
for (int i = 0; i < to.length; i++) {
toAddress[i] = new InternetAddress(to[i]);
}
msg.setRecipients(Message.RecipientType.TO, toAddress);
msg.setSubject(subject);
//Fill the message
msg.setText(message);
Transport.send(msg);
} catch (MessagingException me) {
me.printStackTrace();
}
What exceptions are you getting while sending emails? Are you sure your SMTP server is listening at default port 25? Are you able to manually send the email via Telnet? Also, turn off any firewall while testing this just to be sure.
