I am currently facing an issue with my email data. I have multiple MBOX files containing important emails, and I need to convert them into HTML format so I can easily view and archive them in a web browser. The main concern is data safety—I do not want to lose email formatting, attachments, or header information during the conversion process. I also prefer a method that is easy to use and reliable, especially for handling large MBOX files. Has anyone here tried a safe and effective way to convert MBOX to HTML?
