To install the add-on, you can either use the graphical package management tool, Synaptic, or run sudo apt-get install lightning-extensionĪt the command line.

Ubuntu has an older package in its repositories. After relaunching Thunderbird, the feature will be ready for use.

When you get there, click the Install… button and select the add-on you just downloaded in the file browser. After launching Thunderbird, select Tools | Add-ons… to launch add-on management. To install the Lightning add-on, first visit the Lightning project page and download the file. On top of this, Lightning has a framework to support the development of other interfaces.The add-on can use email to organize appointments via iTIP/iMIP without accessing a server, or it can use a calendar server the application also has 'free/busy' query support. Lightning supports both local and server-side calendars in various formats, including ICS, CalDAV, the popular Google calendar, and WCAP. Sun Microsystems supports the project and has contributed seven developers for more than two years. The open source Lightning implementation, available in more than 20 languages, currently supports the Linux, Solaris, Mac, and Windows operating systems. Because the close ties between the mail client and groupware component offer various benefits, I will focus on Lightning in this article, although many of the options are also supported by Sunbird. In contrast to the Thunderbird add-on, Lightning, it works as a self-sufficient and independent application. Mozilla also offers the standalone calendar, Sunbird. Mozilla Lightning adds a calendar feature, bringing groupware functionality to Thunderbird.

Until recently, the popular Thunderbird mail client lacked native calendaring. Today, the email client is a core desktop application used for communication and contact management.
