You can convert multiple MBOX files at once using SysInfo MBOX Converter, which supports bulk MBOX conversion without requiring you to process each file individually. Launch the software, select the option to add multiple MBOX files or an entire folder, and load the required mailbox data. Preview the added emails, choose the folders you want to convert, and select your preferred output format, such as PST, EML, MSG, PDF, or CSV. You can also apply filters like date range and duplicate removal before conversion. Finally, select the destination folder and start the process. SysInfo MBOX Converter maintains the folder hierarchy, email content, and attachments during bulk conversion, making it convenient for handling large collections of MBOX files.
