Sorry for coming late to Party.These could be the problem in your task if you are using Gmail Server.
- Two Step Verification should be turned off.
- Allow Less Secure App(should be turned on).
- Please Check Your UserName and Password.
- Check the code(which was my Problem), Above three You can change form google help center and by Yourself last one My Experience I can Share with You. You need to Authenticate the Mail server before Communicating the message because it is Challenge Response System By which You are Communicating through the mail.I am sharing code snippets file you can refer not able to format my code by ctrl+K.

This worked for me:
- Login to the gmail account you are sending mail from
- Go to Manage your Google Account -> Security -> Less secure app access -> Turn on access (not recommended)
or
Access the URL:
https://www.google.com/settings/security/lesssecureapps - Turn "Allow less secure apps: OFF" to "Allow less secure apps: ON"

- First of all make sure that all properties should be defined as follows:-
mail.smtp.host=smtp.gmail.com,
mail.smtp.port=25,
mail.smtp.auth=true
mail.smtp.starttls.enable=true
Now,make sure that two step verification is off
Allow less secure app (ON) follow this link :-
https://myaccount.google.com/lesssecureapps
- Also, check your username and password is correct or not.

1.Allow Less Secure App(should be turned on).
2.Check Gmail Username and Password..
public static void main(String[] args) {
final String username = "YourMailId";
final String password = "password";
Properties prop = new Properties();
prop.put("mail.smtp.host", "smtp.gmail.com");
prop.put("mail.smtp.port", "587");
prop.put("mail.smtp.auth", "true");
prop.put("mail.smtp.starttls.enable", "true"); //TLS
Session session = Session.getInstance(prop,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));
message.setRecipients(
Message.RecipientType.TO,
InternetAddress.parse("[email protected], [email protected]")
);
message.setSubject("Testing Gmail TLS");
message.setText("Dear Mail Crawler,"
+ "\n\n Please do not spam my email!");
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e) {
e.printStackTrace();
}
}
}

I have the same error but when I run the app from the terminal, it goes away. My email configuration is provided:
spring.mail.host=smtp.googlemail.com
[email protected]
spring.mail.password=Weddingcard.1
spring.mail.port=587
spring.mail.properties.mail.smtp.starttls.enable=true
spring.mail.properties.mail.smtp.auth=true
spring.mail.properties.mail.smtp.starttls.required=true

You probably got this error because the username and password of the from mail id is not matching. Please recheck your password and mail-id (username). It could be a typo.
In some cases, Gmail prevents logging in through external applications or programs which are not authorised. Also login to your gmail account to check if gmail has prevented logging in to your account via your Java Mail API program.
If nothing works, you could try some other SMTP server (like yahoo, yandex).
