Procedure to transfer Outlook PST to Thunderbird:
1. Convert PST to Mbox (e.g. by using ReadPST -which is rather complicated but I don't know any other sucessful tool)
2 Use the ImportExportTool:
It works, BUT: any folder structure will be lost, i.e., you must sort all your emails once again into the provided (but empty) folders
-> no thanks, I got other business to do

This review is for a previous version of the add-on (3.1).
