I recently switched to a new computer and found some old OST files from my previous Outlook account. Unfortunately, I can not access that Outlook profile anymore, and I need to extract individual emails from the OST file in MSG format for backup and sharing purposes. I have tried opening the OST directly in Outlook, but it does not recognize it without the original account. Is there any reliable method or tool that can help me convert OST to MSG files easily while keeping attachments and formatting intact?
