As promised, i’ll teach you how to sync Google Calendar with Thunderbird today. Now you can sync your Thunderbird with Google Calendar by using Provider for Google Calender add-on. So to sync Google Calendar with Thunderbird you need to install one more plugin for your Thunderbird.
Below is the steps to sync Google Calendar with Thunderbird:-
- Download and Install Thunderbird plugin – Provider for Google Calendar
- If you have no Calendar running, you can skip step 2, 3 and 4. If you already have your current Calendar running, you need to export your Calendar. Go to your Thunderbird Calendar view, click on File -> Export Calendar -> Select your Calendar -> enter a name for the export file and select iCalendar (.ics) at “Save as type:”
- Now, login to your Google Calendar and go to the Left Side bar -> My Calendar -> Click on “Add” and Select “Import Calendar”

- Click on Browse -> select the .ics file you just export out from your Thunderbird -> Choose your calendar and click “Import”

- Go to “Settings” at the top left corner -> Click on “Calendar” Tab -> Click on your calendar name -> Look for Private Adress and copy the url for XML (Right Click -> Copy Link Location).

Google Calendar Private Address for XML - Go to Thunderbird -> File -> New -> Calendar

Really helps a lot, Having a hard time at first but manage to sync my Google Calendar to my Thunder Bird. KUDOS! for the tutorial…
I got to sync my events at sunbird to Google Calendar but failed to sync my google calendar to sunbird. It says the google calendar is momentarily unavailable. What is the problem?
For number 7 above, in place of google calendar, I have these choices: icalendar (ICS), CalDAV, Sun Java System Calendar Server (WCAP) which should I check?
Thank you ever so much! Worked beautifully! :0))
Great help!!!
Thanx a lot.
