Hi Guy's

I currently have a load of E-Mails within Outlook 2011 for Mac and no longer wish to use Outlook but still want my E-Mails which are in it. My question is this: How do I move all the mails within Outlook to Mac Mail? I've tried exporting all the E-Mails from Outlook and then importing into Mac Mail, but Mac Mail does not recognise the format.

If anyone can help me with the above that would be VERY much appreciated. The simplest (and free) way to do this would be great.

Thanks in advance guy's.
