The MBOX Attachment Extractor is a free software tool that retrieves attachments from message base files of MBOX format. Users can easily save attachments from selected folders by specifying the desired location on their drive or network resource and running the utility.

One of the best things about this utility is that it allows you to filter attachment types and names, message dates, and even file sizes. The tool is also capable of recreating the original folder structure of the MBOX files and can even save special attachments such as embedded Outlook items, hidden attachments, and inline attachments in the body of the message.
The benefits of using this software are numerous. Firstly, it extracts attachments to files, while maintaining the folder structure. This ensures that files can be easily located and organised. It is also capable of saving embedded messages, hidden and inline Outlook attachments, and filtering attachments based on name, extension, size, and message dates. This software can process MBOX files from various email platforms including Gmail Takeout, Mozilla Thunderbird, Opera Mail, Eudora, Mac Mail, among others. Additionally, there are no restrictions on the size or number of MBOX files that can be processed.
Saving attachments with this software is straightforward and easy to use. I was able to name and structure folders using macros to group saved attachments by date, message subject, sender, recipient's domain, optional message fields, and other properties. The command line tool that comes with the software allows you to automate the process of saving attachments and run it on a schedule, making it convenient and time-saving.
Overall, I would highly recommend this utility to anyone who regularly manages MBOX files and needs to extract attachments safely and efficiently.
