SOGo Connector extention provides integration of Mozilla Thunderbird with the SOGo groupware solution. It does this by adding support for remote DAV address books and by adding features to the calendar.
To use SOGo calendar, we need to get the link of SOGo Calendar first.
Calendar on top-right cornerChoose the calendar you want to sync (Personal Calendar is the default one),
click on 3 vertical dots, choose Link to this Calendar and copy CalDAV URL.
Note: Some old SOGo releases might use 127.0.0.1:20000 as server
address in the CardDAV URL, you must replace them by the real server
address like https://<your_server_name_or_ip>/SOGo.
