Answer 1

You can also try

head over to the gmail settings > Forwarding and POP/IMAP

from the dropdown of When messages are accessed with POP select mark Gmail's copy as read and save the changes

Answer 2

One liner that will do it WITHOUT downloading the entire message:

single message:

folder.setFlags(new Message[] {message}, new Flags(Flags.Flag.SEEN), true);

all messages:

folder.setFlags(messages, new Flags(Flags.Flag.SEEN), true);

Other methods of calling getContent() or creating a copy with new MimeMessage(original) cause the client to download the entire message, and creates a huge performance hit.

Note that the inbox must be opened for READ_WRITE:

folder.open(Folder.READ_WRITE);

Answer 3

Well this post is old but the easiest solution hasn´t been posted yet.

You are accessing the Message. message.setFlag(Flag.SEEN, true);

Answer 4

for (Message message : messages) {
                    message.setFlag(Flags.Flag.SEEN,true);
                }

and change the below line

folder.open(Folder.READ_ONLY);

to this

folder.open(Folder.READ_WRITE);

Answer 5

You may also consider having a public static int max_message_number, and storing in it the message[i].getMessageNumber(); as soon as you read a message. Then before reading any message just check if the max_message_number < message[i].getmessageNumber(). If true then don't print this message (as it has been already read)

Answer 6

If you are using a for loop to read or check a mail one by one, the code can be as follows to mark a gmail message as read:

    Message[] unreadMessages = inbox.search(new FlagTerm(new Flags(Flag.SEEN), false));
            for (int q = 0; q < unreadMessages.length; q++) {

              unreadMessages[q].setFlag(Flag.SEEN, true);

            }

What this code does is that it makes it unread one by one.

And also folder/inbox needs to be READ_WRITE, instead of READ_ONLY:

folder.open(Folder.READ_WRITE);
