I have few Apple mail archived files that I need to import in outlook 2011 for mac. These archived files contains thousands of important emails and each is quite large in size (largest one is 15GB). I have tried some measires to import these files into outlook 2011 for mac but each failed with an exception every time. I need to import these archived files asap as time is running out and I need some data to finish up my project that is stored in those archived files.

Please help me with genuine solutions.
