I recently switched from Mac Outlook to Apple Mail, and now I need to convert my Outlook OLM files into MBOX format so I can import my emails properly. However, I am not sure which is the best and most reliable method to do this without losing any data, like attachments, contacts, or folders. Can anyone guide me on how to convert OLM to MBOX format effectively? Is there any manual way available, or should I use some dedicated software for better results?
