Thunderbird Community Forum

I'm on Thunderbird 151.0.1 (64-bit).

NB: I have been using app specific passwords for all steps with this.

I previously had nine icloud calendars - my own and those shared with me - synced into Thunderbird. Not all had events in them. Then all the events stopped syncing.

I unsubscribed all the calendars and tried to re-add them with the calendar specific URLs. Initially none of them would re-add.

Got a new app specific password.

Followed online tutorials to try using general login to https://icloud.com and https://webcal.icloud.com. Calendars detected, but would not add into Thunderbird.

Then back to calendar specific URLs, and the calendars are adding, but none of the events.

I've tried adding the calendar feeds to Outlook, which works, so I'm pretty positive it's a Thunderbird problem rather than an Apple problem. If it can't be resolved, I'll have to move onto Outlook, but it's a bad time to do that as I want to resolve some Thunderbird email chain dependent projects first.

Any help very gratefully received.

I have a calendar that is shared by 4 devices. If I snooze or dismiss a reminder on 1 device, it should not affect the reminder on the other devices. Please implement a local snooze option at the individual calendar level.
