Thunderbird Community Forum

Ihave installed and configured Google-4-TBSync addon to synchronise contacts between Google and Thunderbird and all works fine.

Just got an email from Google entitled "[Action Required] Mark AI agent OAuth clients as agentic for Google Workspace MCP by Nov 11, 2026"

Does anyone know if that is sometyhing I need to do for the addon to carry on working?

Thanks

Just updated to Thunderbird 157 and all my calendars are now disabled because the google calendar add-on is not compatible and was disabled. How do I enable my other calendars or move back to 156 while I wait for an update for the google calendar add-on?

I'm running Thunderbird 157 64bit for Google email, Calendar & Tasks. This has worked nicely for months even after the upgrade to 157. Today Calendar & Tasks fail to connect and are completely blank. Apparently the Add-on 128.5.12 (Philipp Kewisch) that made this work has been disabled for some reason. Please don't tell me that Thunderbird has suddenly decided Google Calendar and Tasks just aren't needed by anyone anymore. There is no new connector available that I can find, just a suggestion to go back to an older version of Thunderbird? Please help me understand. Thanks!
