To open an MBOX file in Outlook, you need to convert it to PST format since Outlook doesn’t support MBOX directly. I recommend using MailsDaddy MBOX to PST Converter, which quickly converts MBOX files from clients like Thunderbird, Apple Mail, and others to Outlook-compatible PST format while preserving email structure, attachments, and metadata. Once converted, the PST file can be easily accessed in any version of Microsoft Outlook.
