About ExQuilla

ExQuilla is an addon for Mozilla's Thunderbird email client that allows access to both messages and contacts stored on Exchange Server 2007 - 2015. ExQuilla uses EWS (Exchange Web Services) for access to the server. ExQuilla (for versions beginning with 52.) will work with Thunderbird 52. versions on Windows, Linux, and OSX platforms. (Earlier ExQuilla versions worked with earlier versions of Thunderbird, but are no longer being updated.)

ExQuilla is not free software, but is licensed on an annual basis. New users are granted a free 60 day trial license automatically.
