IMAP folder receives email Twice

I am trying to develop an email listener using Java mail api. I am receiving same email twice, the scenario not happening every time; randomly occurs.

The following code is used to make IMAP connection

try {
            isConnecting.set(true);
            createSession();
            LOGGER.warn("session created "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
            store = session.getStore("imap");
            if(store==null){
                LOGGER.warn("store is null return from here"+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                return;
            }
            store.connect(imapServerAddress, imapLoginId, imapPasswrd);
            LOGGER.warn("Connecting successful "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
            folder = store.getFolder(folderName);
            LOGGER.warn("Folder creating "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
            if (timer == null) {
                timer = new HashedWheelTimer(1, TimeUnit.SECONDS);
            }
            if (idleManager == null) {
                idleManager = new IdleManager(session, es);
            }
            if (folder == null || !folder.exists()) {
                LOGGER.warn("invalid folder exit from here "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                System.out.println("Invalid folder");
                return;
            }
            synchronized (folder) {
                LOGGER.warn("Folder sync "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                folder.addConnectionListener(this);
                folder.open(Folder.READ_WRITE);
                folder.addMessageCountListener(this);

                System.out.println("message count listener added");
                LOGGER.warn("message count listner added "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                if (folder instanceof IMAPFolder) {
                    IMAPFolder f = (IMAPFolder) folder;
                    System.out.println("enter idle");
                    LOGGER.warn("Idle condition "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                    idleManager.watch(f);
                    setIsConnected(true);
                    LOGGER.warn("Folder.watch "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                    DbUtil.updateMediaStream(getIdentifier(), true);
                    isConnecting.set(false);
                    connectionAttempt.set(0);
                    LOGGER.warn("Db updated "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                    System.out.println("idle done");
                    scheduleTask();
                    LOGGER.warn("Scheduler starts "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
                }

            }

            System.out.println(new Date()
                    + "================================== connect() end");
            LOGGER.warn("____________________END connecting "+getIdentifier() +"on Imap"+imapLoginId+" pw "+imapPasswrd);
        } catch (Exception fex) {

                if (connectionAttempt.get() >= 3) {
                    LOGGER.error("Reconnection Failed", fex);
                    connectionAttempt.set(0);
                    throw new IllegalStateException(
                            "Error while connecting mediaStream", fex);
                }
                LOGGER.error("Reconnecting mediastream attempt "
                        + connectionAttempt.get(), fex);
                connectionAttempt.incrementAndGet();
                closeFolderAndStore();
                connect();

        }

The email is received here, the "public void messagesAdded(MessageCountEvent ev)" method calling twice

@Override
    public void messagesAdded(MessageCountEvent ev) {
        Message[] msgs = ev.getMessages();
        System.out.println("Got " + msgs.length + " new messages");
        LOGGER.info("New message received {}" ,msgs.length);
        // Just dump out the new messages

        for (int i = 0; i < msgs.length; i++) {

            try {

                // msgs[i].writeTo(System.out);

                    System.out.println("-----");
                    System.out.println("Message >>" + msgs[i].getMessageNumber()
                            + ":");
                    LOGGER.info("Email Received >>> {}" , msgs[i].getMessageNumber());
                    processEmail(msgs[i]);


            } catch (Exception ioex) {
                LOGGER.error("messagesAdded:getmessagenumber", ioex);
                ioex.printStackTrace();
            }
        }
        try {
            synchronized (folder) {
                if (folder != null && idleManager != null) {
                    idleManager.watch(folder);
                }
            }
        } catch (Exception e) {

This is message number 466 in the mailbox. The server announces the new message:

    * 3 RECENT
    * 466 EXISTS

You process the message:

    A16 FETCH 466 (ENVELOPE INTERNALDATE RFC822.SIZE)
    ...

You wait for new messages, and the server tells you:

    * 466 EXPUNGE
    * 466 EXISTS

That means message number 466 was completely removed from the mailbox and there's a new message number 466 in the mailbox. JavaMail notifies you of the new message number 466. Apparently, it's exactly the same as the removed message number 466.

I have no idea why the server is doing that. It looks like a bug in the server to me. Please report it to Microsoft.

You might want to check the IMAP UID of the messages that you're processing. The new message 466 absolutely must have a different UID. If it doesn't, that's an even more serious bug in the server.

You can also check the Message-ID of the message to make sure you haven't seen that message before. If all the error cases are like this, you may only need to keep a history of one message. But note that while Message-IDs are intended to be unique and are usually unique, unlike IMAP UIDs there's no guarantee that they are unique, or even that they exist at all.
