Unfortunately automatically configuration doesn't work. Autodiscover will loop. testing configuration will loop. Only manual configuration with manually added URL to EWS works as it should. Unfortunately price is too high for that functionality. 45 USD I can spend to fully working email client, not for plugin buggy and poor functionality plugin.

This review is for a previous version of the add-on (38.0.1159.1-let-fixed).
