Elettra Collaboration Calendar OLD (SOGo)

Using an external calendar client (CalDAV)

Regardless of the particular calendar client to configure, the first step is to get a calendar's CalDAV URL. The process is explained in the  "share a calendar" section of this guide.

Mozilla Thunderbird/Lightning

Thunderbird is one of the most email clients (or Mail User Agents, MUA) available. It's free, Open Source, multiplatform (Windows, Mac OS X, Linux, etc.).

Lightning is a Thunderbird Add-on that enables integration with a calendar server like the Elettra Calendar. Starting from Thunderbird version 38, this add-on is preinstalled, so it's not necessary to manually install it.

From the main Thunderbird screen it is possible to see the Lightning part (rightmost area, tasks and events, plus the two icons/buttons above it - new event/task).

To subscribe to a calendar of a user of the Elettra Collaboration Calendar it is necessary to start from the "Create a new calendar" feature, then choose the "On the Network" option.

On the next screen, the right option is "CalDAV"; the Location text box is where to paste the calendar's CalDAV URL (obtained from the  "share a calendar" section). The "Offline Support" comes in hand when wanting to keep the calendar data even when not connected to the Internet.

The next screen can be used to set the (local) calendar name (WorkingGroup in this example), its events colour, whether to show reminders from Thunderbird and which email address will be used when sending (manual) notifications to attendees.

By pressing "Next" and, then, "Finish", Lightning will configure the subscription to the calendar and ask for the credentials needed to access it.

After that, the calendar will appear in Lightning and can be used as the local ones.

Apple Calendar (iCal)
 

Within iCal, it is necessary to go into Preferences > Accounts and then click on the Add (+) button.

 

The picture above displays the needed information to be set for the subscription.

Account Type: must be CalDAV
User Name: your UniPass account (name.surname)
Password: your UniPass password
Server Address: this must be the first part of a calendar's CalDAV URL, up to the username:

https://calendar.elettra.eu/SOGo/dav/name.surname/

After pressing "Create", this calendar account will be visible in the Preferences window.

The URL used when creating this account has been split in several parts, viewable in the "Server Settings" tab. It is necessary that the "Use SSL" checkbox be set.

In different versions of OS X these screens can vary. It may be needed to selectively input the URL in its parts into different texboxes: the above screenshots, however, can be taken as a guide to correctly set the account.

After these steps all the calendars linked to one user's account will be usable from the Apple Calendar (iCal) calendars list.
