JavaMail Exchange Authentication

I'm trying to use Exchange authentication from my app using JavaMail to do this. Could some one give me a guide to do this? After authentication I need to send mails that's the main reason that I'm using JavaMail. All the links that I found talks about problems with this but I think this must be an easy task to do from Java. Thanks in advance.

It is a good question! I have solved this issue.

First, you should import the jar ews-java-api-2.0.jar. if you use maven, you would add the following code into your pom.xml

<dependency>
  <groupId>com.microsoft.ews-java-api</groupId>
  <artifactId>ews-java-api</artifactId>
  <version>2.0</version>
</dependency>

Secondly, you should new java class named MailUtil.java.Some Exchange Servers don't start SMTP service by default, so we use Microsoft Exchange WebServices(EWS) instead of SMTP service.

MailUtil.java

package com.spacex.util;


import microsoft.exchange.webservices.data.core.ExchangeService;
import microsoft.exchange.webservices.data.core.enumeration.misc.ExchangeVersion;
import microsoft.exchange.webservices.data.core.service.item.EmailMessage;
import microsoft.exchange.webservices.data.credential.ExchangeCredentials;
import microsoft.exchange.webservices.data.credential.WebCredentials;
import microsoft.exchange.webservices.data.property.complex.MessageBody;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import java.net.URI;

/**
 * Exchange send email util
 *
 * @author vino.dang
 * @create 2017/01/08
 */
public class MailUtil {

    private static Logger logger = LoggerFactory.getLogger(MailUtil.class);



    /**
     * send emial
     * @return
     */
    public static boolean sendEmail() {

        Boolean flag = false;
        try {
            ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP1); // your server version
            ExchangeCredentials credentials = new WebCredentials("vino", "abcd123", "spacex"); // change them to your email username, password, email domain
            service.setCredentials(credentials);
            service.setUrl(new URI("https://outlook.spacex.com/EWS/Exchange.asmx")); //outlook.spacex.com change it to your email server address
            EmailMessage msg = new EmailMessage(service);
            msg.setSubject("This is a test!!!"); //email subject
            msg.setBody(MessageBody.getMessageBodyFromText("This is a test!!! pls ignore it!")); //email body
            msg.getToRecipients().add("[email protected]"); //email receiver
//        msg.getCcRecipients().add("[email protected]"); // email cc recipients
//        msg.getAttachments().addFileAttachment("D:\\Downloads\\EWSJavaAPI_1.2\\EWSJavaAPI_1.2\\Getting started with EWS Java API.RTF"); // email attachment
            msg.send(); //send email
            flag = true;
        } catch (Exception e) {
            e.printStackTrace();
        }

        return flag;

    }


    public static void main(String[] args) {

        sendEmail();

    }
}
