You can also use this program before deciding on a more reliable option. This app gives you all of the options you'll need to complete the MBOX Conversion. You can also use its free version to import Thunderbird Profile data from MBOX into PST files, which can then be imported into any MS Outlook edition, including 2019, 2016, 2013, 2010, and the below version.
