I have several large Zimbra TGZ mailboxes that I need to export to EML format. My main concern is preserving the original folder structure during the export. I want a method or tool that can handle high-volume mailboxes efficiently without skipping emails or breaking folders. Any solutions or recommended approaches to ensure smooth conversion?
