Hi Lists,

We are proud to share with you the first preview of the successful
OpenChange-SOGo partnership.

For the last 2 months, the SOGo and OpenChange development teams have
been working together on a proof of concept server code designed to
change for real the way people use groupware solutions.

SOGo and OpenChange are converging. We are using the best of our
technology to provide the first real Open Source and Microsoft Exchange
interoperable groupware solution users have been waiting for:

        * OpenChange Server is a transparent and native Exchange
        replacement for Microsoft Outlook users working on top of Samba
        4. With OpenChange, you don't need costly MAPI connectors

        * SOGo is a reliable groupware server with a focus on
        scalability and open standards. Let your Mozilla
        Thunderbird/Lightning, Apple iCal/iPhone, BlackBerry and now
        Microsoft Outlook users collaborate using a modern platform.

The technical component between OpenChange and SOGo servers is MAPIStore
- an abstract storage mechanism with backend support - shipped as part
of OpenChange:
        * For OpenChange, SOGo is the most advanced storage backend
        * For SOGo, OpenChange is the connector for Microsoft Outlook

The current proof of concept code is:
        - read-only from Outlook side
        - read-write from SOGo side
Our next step will bridge the gap and provide a read/write access for
Outlook users in SOGo through OpenChange server, work on free/busy
support and many other exciting features we'll discuss in the future.

The following video however shows the growing power of OpenChange and
SOGo model: 

     1. E-Mails are stored on an IMAP server
     2. Calendar and Contacts are stored in SOGo backend and edited
        through SOGo Ajax-based Web interface
     3. Messages, events, tasks and contacts are directly exposed to
        Microsoft Outlook through OpenChange server and its mapistore
        storage component
