Rated 3 out of 5 stars

Appears to work now. The command appears on the toolbar.

A bit slow, and it would nice to be able to restrict to folders, and pull CC fields.

Thank you for your feedback!

Completely does not work.

This review is for a previous version of the add-on (1.0). 

I'm sorry that this add-on did not work for you - I have published a new version with error reporting, perhaps this could help identify the issue?
