Rated 5 out of 5 stars

Please see the earlier review from August 21, 2017 by aparente001, which explains how to use the plug-in. Without that, I was baffled, thought it just didn't wok. It does work, for both accounts and folders within accounts (TB52.4)
I'll make a donation if it helps get my job done (transferring some corporate email accounts - I want them in nice, tidy order)

This review is for a previous version of the add-on (1.1.1).
