I recently switched from a Linux-based email client that stores mailboxes in MBOX format to Microsoft Outlook on Windows. Now I have several important MBOX files containing business emails and attachments. Outlook does not support MBOX files directly, and I am worried about losing folder structure and message data during conversion. What is the safest and easiest way to convert MBOX to PST for Outlook while keeping emails, attachments, and folders intact? Please suggest a reliable solution.
