Probably better than that is the integration of Google Calendar information into the Lightning add-on as it integrates better with Thunderbird. The requirements are the following: You need Thunderbird 8 or later at the moment as Lightning is only compatible with that version of the email client currently. The developers however have stated that the next version of Lightning will again support previous versions of Thunderbird as well. Lastly, you need a Google account with Google Calendar enabled as a service.

Installing Lightning

Install Lightning in Thunderbird by dragging and dropping the downloaded add-on file into the program window. You can alternatively click on Tools > Add-ons to open the program’s add-on manager. Click the small options icon next to the search and select Install Add-on from File. Locate the Lightning add-on on your computer and select it to install it in the email client.

Restart Thunderbird after you have installed the calendar add-on.

Setting up Google Calendar

Go to the Google Calendar website and log into your Google account. Click on the options icon in the upper right corner of the screen next to the profile picture and select Calendar settings from the menu there.

Switch to the Calendars tab under Calendar Settings and locate the calendar that you want to sync with Thunderbird. Click on that Calendar and scroll down until you Calendar Address and the Calendar ID listed there.

Syncing Google Calendar with Thunderbird

Click on File > New > Calendar to create a new calendar. In the next menu select On the Network from the available options and click Next.

Select CalDAV from the available options and paste in the following url:

https://www.google.com/calendar/dav/[Calendar-ID]/events

with Calendar ID being the ID listed on the Google Calendar page.

You are then asked to enter a name, color, alarms and an email address for the calendar.

If everything has been done correctly the Google login credentials need to be entered on the next page. Once done the new calendar will be displayed in the Lightning calendar in Thunderbird.

With the release of Thunderbird 8 came the release of Lightning 1.0. We already mentioned that in the Thunderbird release review we posted yesterday.

Lightning in terms of compatibility has made a step backwards. The calendar only supports Thunderbird 8 and later versions, which can be a serious problem for users who do not just jet want to upgrade to the new version of the desktop email client.

Mozilla has this to say about Lightning:

Lightning 1.0 is the fully integrated calendar Add-on for Thunderbird that lets users organize their schedules and life’s important events as a natural part of their email experience. Lightning gives users the ability to manage multiple calendars, create daily to do lists, invite friends and colleagues to events and meetings, and subscribe to publicly available calendars. With over a million active users, Lightning 1.0 is the calendar solution that users rely on to help them manage their daily lives at work and at home.

When you look at the release notes of Lightning 1.0 you will notice that there are not really that many notable changes to report. Most of the changes are bugfixes that resolve issues of previous Lightning versions. Lightning 1.0 has received some cosmetic changes, most notable new user interface styles for all calendar views.

When you install Lightning in Thunderbird you will notice – after a restart – that it adds a column on the right side of the program. Here you see the current date and calendar week as well as events for today, tomorrow and “soon”. Lightning adds the Events and Tasks menu to the top menubar.

An import option is available supporting iCalendar and Microsoft Outlook comma separated value files. It is furthermore still possible to synchronize Lightning with Google Calendar and other remote calendar locations (via New > Calendar > On the Network).

New Lightning users should take a look at the known issues highlighted on the Lightning 1.0 release notes page.

Are you using a calendar application? If so, which?

As some of the more regular readers may know, I’m all into the whole ‘portable’ thing, and am constantly looking for ways to use stealthy software, sync my data or access it wherever I go. So it’s not surprising I stumbled across the SyncKolab Thunderbird extension some time ago looking for a possibility to sync my contacts across different computers as easy as my bookmarks using Foxmarks. Didn’t turn out that time, I just couldn’t get it to work.

But now, you may have guessed it already where this is heading, version 1.0 is out and, what can I say, it works like a charm, and not only for my contacts, but for my lightning-powered to-do’s and calendar items as well!

The whole thing uses the Kolab ‘protocol’ (in lack for a better word), which uses iCals and E-Mails containing xml-files to, among other things, store the items in your IMAP-Folder.

There’s a pretty good tutorial how to set it up as well, but it’s principle is rather simple. Choose an IMAP-Account, the items you want to have synced (contacts, calendar and to-do; the latter two require lightning to be installed) and where to store the data in the IMAP folder structure. I used a new folder named Synckolab containing subfolders for each of the groups, though I don’t know if it’s necessary to split them up.

Conflicts are resolved by using a pre-defined setting (always use server-side or client-side), or by asking the user, which is always my personal weapon of choice.

The whole thing also works with a specialized server component as well as different clients such as KDE’s Kontact for instance. Check out the wikipedia-entry if you’re interested.

The extension adds itself seamlessly into Thunderbird. The calendar uses the space beneath your inbox to display the current month and the latest upcoming events.

Clicking on a day loads the monthly view window displaying every day of the month and all the events that you already added to that month.

Right-clicking a day and selecting new event lets you add events to your calendar which can import and export the data into different clients. This is of course pretty useful if you have to use a different calendar at work or another workplace.

We have to use Outlook at work and I never thought of using Outlook at home as well. Lightning lets me use Thunderbird at home and sync the data of my works Outlook calendar easily.

Next to the monthly view window you can of course change to weekly or daily view to view a detailed view of those events.

Lightning for Thunderbird is a great extension that adds calendar functionality to Thunderbird. I would recommend it to everyone who missed that feature in Thunderbird.
