Rated 1 out of 5 stars

the only reason that it is possible to sell this plugin is because of brand locking. people like me who have been using thunderbird for years have a great database in it which is almost impossible to migrate into other open-source projects like evolution, which supports ews by a free (as in beer and as in bird) plugin. I would rather accept the hardship of running two email programs than shame myself by using closed source plugins on a gnu/linux system.

This review is for a previous version of the add-on (24.5.3).
