Outlook .Pst Import Apple Mail .mbox

Question

Well not having much knowledge about every mail client's functioning, only knowing the file formats and other basic user's usage, I have to Import mails from windows Outlook 2010 to apple mail on my mac book pro.

I have tried many step following methods but none of them seems to be importing mails entirely, every time i end up with messed up mail boxes and its contents.

How can I transfer all my mails from windows outlook 2010 to mac apple mail, saving all my folder hierarchy and the data in the mails.

You help will be appreciated.
Thank you
