A while back for security reasons I backed up all my emails on my hard drive with the help of export function in Apple Mail. Exporting the email files created a single .mbox file on my hard drive (approx 27GB). Now as my mac is too old now and I have switched over to Windows system, I needed to know how can I import this .mbox file in my windows outlook. I am using the latest version of Office 365 but I couldn't make out how to import this apple mail exported file into windows outlook. I have some import emails and attachments that I need to access now and will also need in future. Please help.
