Switching Mail database from Windows Outlook to Apple Mail.

First of all, let me explain to you that you cannot move the emails from Windows Outlook to Apple Mail directly both these email clients use different email database formats. Windows Outlook uses .pst and Apple Mail uses .mbox. So in order to import files from Windows Outlook to Apple Mail, you will need to change the format of the Windows Outlook .pst files to Apple Mail .mbox files. This cannot be done without the help of a converter, and there are multiple third-party converters available online to do such format change. One that is available and recommended by Apple is: https://itunes.apple.com/in/app/pst-converter-pro/id446401009?mt=12

 

I hope this helps and makes things clear. Thanks
