I was searching for a way to transfer my emails and folders from a Mac to Outlook 2013.
Some will re-synch via IMAP but the majority are in folders on the Mac that I can't move to the IMAP inboxes.
I looked at this software from the link below and it's in exe as well as dmg format.

I contacted the company and they explained how to use the software by exporting the mail to an external drive (if using the exe format) and also how the
mac version automatically detects the apple mail files converting them to pst format in couple of clicks.
