How to send mail in java using outlook

To send an email using Outlook in Java, you'll need to use the JavaMail API and the Outlook COM API. Here's a step-by-step guide to help you achieve this:

Prerequisites:

  1. Install the JavaMail API: You can download the JavaMail API from the official website: https://javaee.github.io/javamail/
  2. Install the Outlook COM API: You'll need to install the Outlook COM API on your system. You can download it from the Microsoft website: https://www.microsoft.com/en-us/download/details.aspx?id=40302
  3. Set up your Outlook profile: Make sure you have an Outlook profile set up on your system, and that you can access your email account using Outlook.

Code Example:

Here's an example code that demonstrates how to send an email using Outlook in Java:

import javax.mail.*;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
import com.sun.mail.smtp.SMTPTransport;

import java.util.Properties;

public class SendEmailUsingOutlook {
    public static void main(String[] args) {
        // Set up the Outlook COM API
        String outlookPath = "C:\\Program Files\\Microsoft Office\\root\\Office16\\OUTLOOK.EXE";
        String outlookProfile = "Your Outlook Profile Name";

        // Set up the JavaMail API
        Properties props = new Properties();
        props.put("mail.store.protocol", "smtp");
        props.put("mail.smtp.host", "smtp.office365.com");
        props.put("mail.smtp.port", 587);
        props.put("mail.smtp.auth", "true");

        // Create a session
        Session session = Session.getInstance(props, new Authenticator() {
            @Override
            protected PasswordAuthentication getPasswordAuthentication() {
                return new PasswordAuthentication("your_email_address", "your_email_password");
            }
        });

        // Create a message
        MimeMessage message = new MimeMessage(session);
        message.setFrom(new InternetAddress("your_email_address"));
        message.setRecipient(Message.RecipientType.TO, new InternetAddress("recipient_email_address"));
        message.setSubject("Test Email");
        message.setText("This is a test email sent using Outlook in Java");

        // Send the message using Outlook
        SMTPTransport transport = (SMTPTransport) session.getTransport("smtp");
        transport.connect("smtp.office365.com", 587, "your_email_address", "your_email_password");
        transport.sendMessage(message, message.getAllRecipients());
        transport.close();
    }
}

Explanation:

  1. The code sets up the Outlook COM API by specifying the path to the Outlook executable and the name of the Outlook profile.
  2. The code sets up the JavaMail API by specifying the SMTP host, port, and authentication details.
  3. The code creates a session using the JavaMail API and authenticates using the Authenticator class.
  4. The code creates a message using the MimeMessage class and sets the from, to, subject, and text fields.
  5. The code sends the message using the SMTPTransport class, connecting to the SMTP server and authenticating using the same credentials as the JavaMail API.
