I am pleased to announce that ExQuilla, a Thunderbird addon that provides access to messages and contacts in Microsoft Exchange Server, is now available. This is a beta-quality release. ExQuilla is currently only available for Windows, in English, and supports Thunderbird version 9, 10, and 11. Linux and Mac versions are planned for the future.
This version supports access to messages and personal contacts from a Microsoft Exchange Server 2007 or 2010 using Exchange Web Services (EWS). Calendar support is not currently enabled, but is under development.
For an overview of ExQuilla, visit the ExQuilla support site.
