I'm looking for any existing scripts or methods that can be implemented in an automated system. (Solutions can contain python,javascript,php)

Try using Admin SDK Groups Migration Service in App Script.

A code snippet is provided for you to try:

function migrateMessages() {
  var groupId = 'exampleGroup@example.com';
  var messagesToMigrate = getRecentMessagesContent();
  for (var i = 0; i < messagesToMigrate.length; i++) {
    var messageContent = messagesToMigrate[i];
    var contentBlob = Utilities.newBlob(messageContent, 'message/rfc822');
    AdminGroupsMigration.Archive.insert(groupId, contentBlob);
  }
}

/**
 * Gets a list of recent messages' content from the user's Gmail account.
 * By default, fetches 3 messages from the latest 3 threads.
 *
 * @return {Array} the messages' content.
 */
function getRecentMessagesContent() {
  var NUM_THREADS = 3;
  var NUM_MESSAGES = 3;
  var threads = GmailApp.getInboxThreads(0, NUM_THREADS);
  var messages = GmailApp.getMessagesForThreads(threads);
  var messagesContent = [];
  for (var i = 0; i < messages.length; i++) {
    for (var j = 0; j < NUM_MESSAGES; j++) {
      var message = messages[i][j];
      if (message) {
        messagesContent.push(message.getRawContent());
      }
    }
  }
  return messagesContent;
}

  • I'm not attempting to move it to a google group. I want to move the emails to another user account. USE CASE: User A is to be deleted, and I want emails moved to User B before they get deleted along with the account. – Jeremiah Gibson Sep 06 '16 at 17:32

  • Thanks for the continuing support. However I need to programmatically do it this as it happens frequently. – Jeremiah Gibson Sep 08 '16 at 16:01
