Thunderbird 78.9.1 Calendar keeps dropping attendees from my invitations?
Folks, I am recent migrant from Microsoft Outlook to Thunderbird and have been very impressed! So much so that I went all out and upgraded to latest 78 release across both my Windows 10 desktop and Linux (Ubuntu 20.04) laptop (yeah!), I also configured both "Provider for Google Calendar" and "TbSync" to ensure calendar sync across all my gmail and hotmail email accounts. For the most part it is all working fine and I can see all my events on both of my Thunderbird clients as well as on the web calendars. However since version 78 upgrade, I have noticed a peculiar problem - for all my invitations created either in Thunderbird or on Google Calendar in the web browser - the events are getting sync'd but any attendees that I invite - they get dropped off at some point of time (I can't be sure exactly at what point but at least in one scenario it happened after they accepted my invitation, and I indeed received the acceptance notification! But just before the meeting was supposed to start, my guest attendee called me to ask for the web conference link as the meeting disappeared from his calendar! And sure enough, he dropped off from my list of attendees!).
Any ideas on how I can fix this? It is rather worrying as I do have quite a few standing meetings with my different mail accounts and I just don't know what my calendar (or one of the two add-ins that I have enabled for calendar sync) is doing behind my back - potentially cancelling all these events?

Do you have both the Provider for Google Calendar and TbSync enabled at the same time? I would choose one or the other, preferably TbSync, and see if it affects attendees. To sync Google calendar (and contacts) with TbSync, you have to also install Provider for CalDAV & Card DAV, and double-click extensions.dav4tbsync.googlesupport to true in Config. editor (in Options or Preferences, General). Another approach is to add the calendar directly without add-ons: https://support.mozilla.org/en-US/questions/1304356#answer-1368791
Thanks for prompt response. I use "Provider of Google Calendar" to sync my Google Accounts' calendars and "TbSync" for my Hotmail Account's calendars. With previous version of Thunderbird, it worked like a charm. I followed your suggestion to install "Provider for CalDAV & Card DAV" and then tried to configure one of my Google Accounts for calendar sync in TbSync - both using automatic discovery as well as by providing the server url for my google calendar as per https://webdav.io/webdav/caldav/caldav-google-calendar/ instructions. But I get no response error the add-on is unable to reach the server. I made sure that the extensions.dav4tbsync.googlesupport is set to true. :(
UPDATE: Restarting Thunderbird after the config update, and re-adding the "Provider for CalDAV & Card DAV" now gives me new options in TbSync to directly add a Google account. I will further update on this thread if this resolves my issue! - Thanks
UPDATE: Indeed after removing "Provider of Google Calendar", adding "Provider of CalDAV & Card DAV", enabling extensions.dav4tbsync.googlesupport (in this order), restarting Thunderbird and next adding all of my Hotmail and Google Accounts for sync using TbSync and then also making sure that each of the calendar has correct corresponding email address associated with it (otherwise add attendees option remains disabled!) - I got it working just fine - on my Windows 10 NUC, Ubuntu laptop as well as on the web browsers!
THANK YOU!

I have the same problem but I don't have TbSync or CalDAV. The solution doesn't work for my case. I have version 78.8.1 (64 bit) for Linux (Kubuntu 18). I am only using the Google Provider and FileLink Provider extensions.
