Making Provider for Google Calendar Work for You
Now that you have it all ready to go, what's next? First, you have to get your Google Calendar information. To do this, log into your Google Calendar and then click the down arrow that is to the right of the calendar you wish to use with Provider for Google Calendar. Choose "Share this Calendar."
Scroll all the way down the page and find the public and private XML addresses for your calendar. Copy the address that fits your needs.
Now that you have the XML address, let's go back to Thunderbird and Lightning where you can configure it with this XML information.
In Thunderbird, click on "File" and then "New" and choose the "Calendar" option.
In the "Create New Calendar Window," click the "On the Network" option.
Now click "Next." and then choose "Google Calendar." Paste in your calendar's XML address in the space provided.
Next, complete the login information for your calendar, enter a name to reference it, and then click "Finish." Your Google Calendar is now accessible in Lightning.
You will have all the tasks from your Google Calendar as well as all of your Google Calendar events visible in your Lightning interface from within Thunderbird.
