Mozilla Thunderbird and Lightning#

Alternatively, you can access SOGo with a GroupDAV and a CalDAV client. A typical well-integrated setup is to use Mozilla Thunderbird and Mozilla Lightning along with Inverse’s SOGo Connector plug in to synchronize your address books and the Inverse’s SOGo Integrator plug in to provide a complete integration of the features of SOGo into Thunderbird and Lightning. Refer to the documentation of Thunderbird to configure an initial IMAP account pointing to your SOGo server and using the user name and password mentioned above.

With the SOGo Integrator plug in, your calendars and address books will be automatically discovered when you login in Thunderbird. This plug in can also propagate specific extensions and default user settings among your site. However, be aware that in order to use the SOGo Integrator plug in, you will need to repackage it with specific modifications. Please refer to the documentation published online.
