I recently migrated from an email client that stores all mail in MBOX format, and now I need to convert several important MBOX files into a more usable format, such as PST or PDF. These files contain business emails, attachments, and folder structures that I cannot afford to lose. I tried a few manual methods, but some emails were missing, and attachments were not opening properly after conversion. What is the safest way to convert MBOX files without losing data, folder hierarchy, and email integrity?

Hello,

Could you please clarify whether you're looking for a component in a specific programming language to accomplish this task, or whether you'd prefer a manual tool to complete it?

Sincerely,
Amy
