Rated 5 out of 5 stars

I needed to export Outlook to Thunderbird, and this was part of the solution (Importing MBOX file). It also has some other very useful functions which I will use in the future. Thank you.

This review is for a previous version of the add-on (14.1.6).

Thanks for the kind review.
Very glad you find ImportExportTools NG useful.
