Thunderbird 60.5.0, Lightning 6.2.5, Provider 4.4.2.
**STILL** cannot dismiss meeting/calendar events and alarms. Tried to dismiss a single item, or ALL past ones. Nothing works, and my only option is to completely disable Lightning and Provider, otherwise there will permanently be a non-closable window showing passed events for the past two months or more. I am stuck using a Google Chrome window for my company calendar (Chrome, yech).

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 188.8.131.52).
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.
