This is a bridge between Exchange web services java API and JavaMail API
You will need the EWS url to connect, something like https://owa.example.com/ews/exchange.asmx and maybe a username and password
#Reading emails
//Initalize a session
Session session = Session.getInstance(new Properties());
//Get the EWS store implementation
Store store = session.getStore("ewsstore");
//Connect to the Exchange server - No port required.
//Also connect() might be used if the session is initalized with the known mail.* properties
store.connect("https://example.com/ews/exchange.asmx",
"test@example.com",
"password");
Folder folder = store.getDefaultFolder();
folder.open(Folder.READ_ONLY);
Message[] messages = folder.getMessages();#Sending emails
//Initalize a session
Session session = Session.getInstance(new Properties());
//Get the EWS transport implementation
Transport lTransport = session.getTransport("ewstransport");
//Connect to the Exchange server - No port required.
//Also connect() might be used if the session is initalized with the known mail.* properties
lTransport.connect("https://example.com/ews/exchange.asmx",
"test@example.com",
"password");
//Create a message as before
Message lMessage = new MimeMessage(session);
lMessage.setRecipient(RecipientType.TO, new InternetAddress("user@example.com"));
lMessage.setSubject("Hello World!");
lMessage.setText("Hello World!");
//Send the mail via EWS
lTransport.sendMessage(lMessage, lMessage.getRecipients(RecipientType.TO));
