To export MBOX to Outlook, the manual way involves setting up an intermediate email account (like Gmail with IMAP), importing MBOX into an email client (like Apple Mail/Thunderbird), and then syncing it with Outlook. But this process is complicated and time-consuming.
A simpler option is to use a professional tool. I recommend Stellar Converter for MBOX, which directly converts MBOX files into PST format that you can easily import into Outlook. It preserves folder hierarchy, attachments, and email integrity, making the migration quick and hassle-free.
