Rated 5 out of 5 stars

Used the ImportExportTools EXPORT PROFILE option before wiping my computer and performing a fresh install of Windows 10.
After installing Thunderbird and adding ImportExportTools again I used the IMPORT PROFILE option and it worked perfectly. (Mailboxes, folders, addresses, THE LOT! )

TOP TIP: During the import process, select the folder then just type whatever you like in the box 'Name of the profile to import'.

This review is for a previous version of the add-on (3.2.4.1).
