I'm using Thunderbird 68.11.0 on Fedora32 with Provider for Google Calendar and Lightning installed, on regular GMail/Google Calendar, not G-Suite. I would like to be able to do the following: * Use my business email address ([email protected]) to create and share and modify calendar invitations with colleagues and be able to sync it with my [email protected] account. My business email address is associated with my [email protected] account. * Share my calendar with co-workers and others on the Internet * Invite others using my [email protected] address instead of the [email protected] account. I've set up my "Location" as: googleapi://[email protected]/?calendar=user%40gmail.com I'm able to connect with my [email protected] address on Thunderbird, but not able to accept incoming addresses using Thunderbird. Currently when trying to accept an invitation, Thunderbird reports "No writable calendars are configured for invitations, please check the calendar properties," despite it saying the calendar is writable in "properties". What am I doing wrong? Is it possible to create invitations as [email protected] and be able to share that calendar with others so they see it as [email protected] and not my [email protected] address?
