When I changed my platform from Mac to Windows, i.e. from Apple Mail to Outlook on Windows, the main issue for me is accessing Apple Mail MBOX files to Outlook. My colleague offered me MBOX to Outlook PST Converter and I am fully contented with it.
Simply handling program with bulk conversion facility impressed me when I checked freeware edition. I instantly bought the software.
Powerful software! It helped me to move complete data of Thunderbird to Outlook 2016 without any confusions. A big thanks to developers.
