Getting 2-way sinc to work with thunderbird

[Flavius Aspra]

Hi

I've tried various approaches to get thunderbird to have 2-way sync with team calendars for confluence.

Basically my confusion starts at the screenshots shown here https://confluence.atlassian.com/teamcal/subscribe-to-team-calendars-from-thunderbird-946631710.html being outdated.

I'm using the cloud version, still in trial.
