How do I import emails in Outlook 2011 from mac mail

I have troubles in operating mac mail, so I bought Microsoft Outlook 2011 for Mac.
I have successfully transferred the contacts but I am unsuccessful in migrating the emails.
I have thousands of mails arranged in different folders, all I want is to transfer all the folders along with the folders.

Would someone have good news for me and find a way to transfer all the mails with their categories from Apple Mail to Outlook 2011 for Mac ?

It would be nice and to receive a positive answer.

Thank you for your help
