(Updated: added a missing screengrab)
With the latest versions of Thunderbird, and the Lightning and Provider for Google Calendar add-ons, Thunderbird now supports full Gmail Calendar and Tasks synchronisation. As the setup has changed somewhat from previous versions of these add-ons we’re going to cover the current procedure in this blog post.
We are using Thunderbird 31.2.0 on Ubuntu 14.04.
If you’ve already installed these two add-ons and you’re synchronising your Gmail calendar, please delete the calendar from Thunderbird (this unsubscribes from the calendar only, and leaves all server-side data intact), and uninstall the add-ons. Restart Thunderbird to get back to a clean-slate state.
Now, using the Thunderbird Add-ons Manager, search for and install both the Lightning and Provider for Google Calendar add-ons:
Restart Thunderbird to complete the installation process.
Next, switch to the Calendar tab in Thunderbird. Right-click in the area where the default Thunderbird calendar is visible and create a new calendar:
We now work through the “Create New Calendar” wizard. In the first two screens that appear, we want to add a calendar on the network, and this should be a Google Calendar:
You’ll now be prompted to enter your email address: this should be the Gmail address of the associated calendar you wish to synchronise:
Thunderbird will then list the calendars and task lists available to be synced. Tick these as you need:
If all goes well you’ll see a dialogue indicating the wizard has finished, and, after a brief delay (during which the interface might not be responsive) your Gmail Calendar and Tasks will be synchronised:
At the far right-hand-side of the above screengrab you can see our tasks lists (only containing a single task in this example). These are synced with your Gmail account.
