Review for Provider for Google Calendar by James E. LaBarre
Rated 3 out of 5 stars
Works good on my home system, with a regular GMail account. However, it fails on my work email (corporate account through GSuite (using the company domain name in the email address). Fails with the message "This version of the provider has expired, please update to the latest version". Problem is, this **IS** the latest version (v4.4.2), listed as being supported with Thunderbird 60.2.1 (lightning 6.2.2.1).
Really don't like having to leave a Google Chrome window open just to get my calendar, but that's the only solution that works now. I hate Google Chrome.
