An MBOX file is another well-known file format; it contains multiple files in a single file.


MBOX files, unlike OLM files, are compatible with multiple email clients, including Thunderbird, Mac Mail, IncrediMail, etc. The MBOX file is superior to OLM because the entire folder can be saved in a single file, making it simpler to export. In addition, cross-platform compatibility allows users to export their data to both Windows systems. Users combine OLM files into a single MBOX file for this reason.
