Thunderbird Support Forum

I have a custom domain (me@mydomain.com) with email / contacts / calendar hosted by Google Workspace. I initially managed to add both the email and calendar account to Thunderbird but recently the calendar stopped syncing.

I tried to fix the problem by first removing the calendar account. This did not work because the 'Create New Calendar' -> 'On the Network' account wizard does not prompt me for the Google OAuth2 login page but just asks me for a password and fails. I tried to supply several 'Location:' URLs like gmail.com, calendar/accounts.google.com but none lead to the Google OAuth2 page.

Finally I removed the email account too and re-added it. During the new account setup workflow Thunderbird seems to look for calendars too but failed to find any...

How do I proceed? How are you supposed to set up a Google Calendar on a custom domain using the OAuth2 sign-in procedure?

Most of my calendar entries (events) generate a corresponding "blue dot" on the mini-calendar for the dates of those events. However, some events do not generate that blue dot for its respective date(s). In my case, I have an event that spans multiple days (NOT an "All day Event"--it's from 3:00 p.m. on 11 July through 4:00 p.m. on 13 July), but there is no blue dot on those days on the mini-calendar. (See image attached.) Other events set up the same way do have the blue dots. Is there something about how events are set up that might not generate the blue dot?

My calendar is Baïkal 0.8.0 running an a debian 10 server. My thunderbird is 115.12.0 (64-Bit) running on Ubuntu 22.04.4 LTS My other devices are two thunderbirds 115.12.0 (64-Bit) running on Ubuntu 22.04.4 LTS and aCalandar 2.8! running an Android 14

It does not matter on which client I add or change calendar entries then synchronize them (I can see on my Baikal dahboard, that the synchronization has succeeded!) the other thunderbird clients don't show the changes, even after explicite synchronization, only after unsubscribing and then new subscribing.

Please advice for help!

Thanks in advance

Hello! I'm trying to subscribe to the calendar at this link: webcal://github.com/othyn/go-calendar/releases/latest/download/gocal__community_day.ics

But when I add the calendar to Thunderbird using New Calendar... > On The Network, it resolves that URL to this very long different URL: https://objects.githubusercontent.com/github-production-release-asset-2e65be/580172601/b8d41b00-ad34-4a4f-937b-55ab6a554213?X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=releaseassetproduction%2F20240625%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20240625T114538Z&X-Amz-Expires=300&X-Amz-Signature=10a1c88bd26110f81b16dd6f839ce758de482cc6c450135e518550bb3eed5840&X-Amz-SignedHeaders=host&actor_id=0&key_id=0&repo_id=580172601&response-content-disposition=attachment%3B%20filename%3Dgocal__pokemon_spotlight_hour.ics&response-content-type=application%2Foctet-stream

The resulting calendar then works for one day but then disables itself and cannot be re-enabled (if I try to enable the calendar, it immediately disables itself again). I think this is happening because the calendar at the webcal link updates to a new file every day, so the specific link that Thunderbird resolves to becomes invalid on a daily basis. Other calendar applications that I use (like the iOS calendar app and the web interface for mailbox.org) do not resolve the link (they just leave it as webcal://github.com/othyn/go-calendar/releases/latest/download/gocal__community_day.ics) and they work fine, which is why I think the link resolution is causing the issue.

Is there a way to get this type of webcal link to work with Thunderbird?

I also filed a bug report here https://bugzilla.mozilla.org/show_bug.cgi?id=1906077

I have used Thunderbird for many years. I had a problem viewing a jpg file that I couldn't resolve and decided to uninstall Thunderbid to install it again. Mail is working smoothly but I can't access my multi-year Calendar. I've tried several alternatives with no solution and I really need help please. I'm in Portugal and I'm Portuguese. My English is Google Translate's English. Thank you.
