TBSync (for Calendar and Contacts)
1. Open Thunderbird client and go Add-ons and Themes.
2. Install TBSync and Provider for CalDAV & CardDAV add-ons.
3. Open the TBSync account manager by clicking on Tools -> Add-on Preferences -> TBSync. Then, Click on Add new account (at the bottom left) -> CalDAV & CardDAV.
4. Select Automatic Configuration and click on Next.
5. Then provide the following configuration details:
Account name: Display name of your account.
Username and Password of your account.

6. Click on Finish.
7. Once done, you can then open your TBSync account manager and check Enable and synchronize this account.
- The list will include both your private and group resources (except for other calendars: group member calendar, external calendar).
