Elettra Collaboration Calendar OLD (SOGo)

Address Book

The Elettra Collaboration Calendar not only manages centralised calendars: it also has an Address Book module that, similar to the Calendar one, can be used both via the web interface and via a Calendar Client (CardDAV).
The Address Book can be accessed by clicking on the "Address Book" tab on the top of the browser window (between Calendar and Preferences).

Multiple address books can be managed and shared, very similar to any calendar.

To include an address book into one CardDAV client (again, like Mozilla Thunderbird), it is necessary to use the Calendar's CardDAV URL (right-click on the address book, Properties, Links to this address book).

In Thunderbird, open the Address Book, then follow the File > New... > Remote Address Book menu path and input the URL above. This way the CardDAV client will synchronise with the Elettra Calendar Server: when using multiple computers or programs, this will result in having the same address book in every place, a guarantee of consistency.
