Mozilla Sunbird, Thunderbird "Lightning"

Mozilla Sunbird is a free, open source, cross-platform calendar application developed by the Mozilla Foundation and many volunteers.
It is currently developed as a standalone version of the Lightning extension for Mozilla Thunderbird that provides the calendaring functionality to the mail management application.

Lightning is an extension that adds calendar and scheduling functionality to the Mozilla Thunderbird mail and newsgroups client. Lightning is an iCalendar compatible calendar.

It is possible to synchronize Events and Tasks between Sunbird/Lightning and IceWarp Server.

To synchronize Contacts, you can use SOGo Connector Thunderbird extension (free, Win/Mac). Available at http://www.sogo.nu/english/downloads/frontends.html.

To set synchronization for these clients, do the following:

1. In the client main menu, select the File – New Calendar... items (or simply use CTRL+L shortcut) to create a new calendar.
2. On the first Create New Calendar – Locate your calendar wizard page, select the On the network option and click Next.
3. Toggle the Format radio button to CalDAV and fill in the Location field.

   Location formats are:

   • for Events http://<server>/webdav/<email_address>/Events/

   • for Public Folder Events (or other nested folder) http://<server>/webdav/<your_email_address>/<email_folder_tree_structure>/

   (Example of email folder tree structure: Public_Folders/Marketing/Events/

   NOTE: If there is a white space used (e. g. Public Folders), you have to replace it with "%20".)

   • for Tasks http://<server>/webdav/<email_address>/Tasks/

   Example: see the following figure.

   

   NOTE: Examples given above refer to English folder names. However, any folder names (even localized ones with diacritics) are supported.

   In this case, users should add Locations using the real folder names they see in their WebClients.

   E. g.: User has a calendar folder named "Calendário". To see this folder in Sunbird the CalDAV URL in Sunbird should be:

   http://<server>/webdav/<email_address>/Calendário/

   Because the folder name contains diacritics, the URL part with the diacritics will be URL encoded:

   http://<server>/webdav/<email_address>/Calend%C3%A1rio/

   NOTE: You can also subscribe folders that some other users share with you. The correct syntax is:

   http://<server>/webdav/<other_user's_email_address>/<folder_name/

   E. g.: http://mail.mycompany.com/webdav/mike@mycompany.com/Events/

   Click Next.

4. On the Customize your calendar page, name the calendar. Optionally, select the calendar color and switch on/off showing alarms. Click Next.
5. In the Authentication Required dialog, fill in the User Name and Password fields.

   NOTE: You have to use your full email address as your user name. This applies always – regardless of the server login policy.

6. Click OK to finish setting.
