If you prefer an easier and more flexible method to import MBOX to ProtonMail, try Advik MBOX Converter. This software offers batch MBOX migration, so you can import multiple MBOX files at once by using the Add Folder option. It keeps your folder structure and attachments perfectly intact. You can choose between “Add Files” to pick specific MBOX files or “Add Folder” to load an entire folder of files in one go. The tool has a clean interface, so even if you’re not technical, you can follow the steps easily. It also supports direct import to ProtonMail using the IMAP Server option—just enter your login, IMAP host, and port number, and start the export. Plus, it works on all Windows versions, including Windows 11, 10, and older systems.
