Rated 4 out of 5 stars

Works as designed, but does not detail the non-free licensing model in the short description, as for example searching/installing it in Thunderbird, which is plain deceptive, as I would not have installed it otherwise. Free software exists to perform this functionality, it just requires additional work, which I'm assuming most individuals who turn to Thunderbird for Exchange are willing to research.

Edit: After Developer's update below addressing my problem I have revised my rating. There are still some issues to work-out using this add-on and then removing it however. For example, the associated email account must also be removed before removing the add-on, otherwise it won't be present or available to re-add. Functionality still works as intended.

This review is for a previous version of the add-on (38.0.1160).

Mozilla support for non-free addons is miserable, as most such sites would have clear markers between paid and non-paid. The license model has always been clear in the description, but I'll also make it clear in the summary
