I had the same problem a while ago and used the Softaken MBOX to PDF Converter to fix it. You don't need to know anything about technology to use this tool. You only need to choose the MBOX files you want to convert and where you want the PDFs to be saved. The best thing about it for me was that it kept the layout of the original email and added files. It saved me a lot of time because I could convert several files at once. I've tried some free tools in the past, but they either let me send fewer emails or formatted them badly. This one just worked fine. I think you should give it a try if you want an easy way to do it.
