ZEG, which stands for "Zero Effort Groupware", is a virtual appliance of SOGo intended to provide a complete out-of-the-box testing environment. SOGo is a collaboration suite (or groupware) with speed and scalability in mind. It offers calendaring, address book management, and a full-featured Webmail client along with resource sharing and permission handling. It also makes use of documented standards (CalDAV, CardDAV and GroupDAV, vCard, and vCalendar/iCalendar) and thereby enables the use of many clients and the reuse of any existing infrastructure. The appliance is prepared to be imported in VirtualBox but can also used in VMWare.
Inverse SOGo Connector for Thunderbird is an extension which transforms Thunderbird into a full DAV client for groupware servers such as SOGo, OpenGroupware.org, and Citadel. It does this by adding support for remote DAV address books and by adding features to be used along with the Lightning calendar extension. It is a merge of the Lightning Enhancer and the GroupDAV Addressbook Connector.
Inverse Lightning enhancer plugin enhances the functionalities of the Lightning calendar plugin for Thunderbird. It is meant to add better integration with CalDAV compatible servers such as SOGo. It provides support for CalDAV freebusy information in the scheduling interface and in the addressbook. It manages the iCalendar organizers by taking into account the identities configured in Thunderbird. And it fixes bugs found from time to time in Lightning which are not yet fixed upstream.
SOGo is a very fast and scalable modern collaboration suite (or groupware). It offers calendaring, address book management, and a full-featured Webmail client along with resource sharing and permission handling. It also makes use of documented standards (IMAP, CalDAV, CardDAV, etc.) and thereby provides native connectivity (without plugins) to many clients such as Microsoft Outlook, Apple iCal, the iPhone, Mozilla Lightning, and a plethora of mobile devices via SyncML. It can reuse any existing email and database infrastructure, avoiding long hours of site restructuring.

Scalable OGo (SOGo in short) is a groupware server built around the SOPE application server. Unlike OGo, it is focused on scalability instead of depth in functionality. The Web interface uses human-readable URLs and can be accessed according to REST Web service ideas. Notably, it requires no server side session at all. The server stores all internal data in the iCalendar format, and therefore has no data model inconsistencies with native clients. It easily connects using GroupDAV connectors.

A version of the Web client, Zimbra Desktop, also works offline with any POP/IMAP server. Administrators can control live backup/restores of individual or groups of mailboxes, hierarchical storage (HSM) and clustering, LDAP directory configuration, Web services integration with existing enterprise applications, and integrated anti-spam and anti-virus.
