How Can I Maintain Email Metadata in MBOX to MSG Conversion?

I am planning to convert a large number of emails from MBOX to MSG format for use in Microsoft Outlook. My main concern is preserving important email metadata such as From, To, CC, BCC, Subject, Date & Time, Message-ID, and attachment details during the conversion. I have already tried a few manual methods, but after conversion, some emails show incorrect sent dates and missing header information. This is creating problems for compliance and record-keeping purposes. How can I maintain complete and accurate email metadata while converting MBOX files to MSG format? Please suggest a reliable and practical solution for this situation.
