Clocks went back one hour in Santiago, Chile last week and Thunderbird does not recognise the new time, although Windows (10) does.

The calendar line show the current time to be one hour ahead of the time on Windows; i.e., the Windows time has updated correctly, but the calendar time has not. Adding non-local events to the calendar causes them to be displayed one hour ahead of the correct time.

Changing the calendar setting to use the system timezone, or use America/Santiago has no effect that I can see.

Typing Date() in the error console of Thunderbird gives the correct time, as per Windows.

This also happened in the last time change here in Chile.

How can I fix the Calendar to see the same time as Thunderbird and Windows?

There is no way to create a recurring task in Thunderbird - it seems like they are simply not supported. I've set the synchronization with my Google tasks but when trying to finish the recurring task through TB the synchronization error appears like I've updated the task on the server. Are there any plans to support recurring tasks?

The attendees I select are not receiving their invites to my calendar events. My version of Thunderbird (TB) is 115.9.0 (64-bit). I check my sent folder and it does not send. Older versions of TB, the Calendar invite worked and I can see it was sent from the sent folder. Please note that I am not tech savvy and I need a solution that an average person can employ. If someone has a solution, please get it in step by step instructions and assume I know next to nothing.

I would like to have a unified calendar that when an event is added to my gmail or outlook calendar it gets copied to the unified calendar.

Is that possible?

I cannot dismiss calendar invites sent to me from others on the Ubuntu platform. I can dismiss invites that I have initiated. FYI this doesn't seem to be the case on the windows release - I can dismiss "foreign" invites.

The only way to dismiss these invites is to delete them from my calendar (which I prefer not to do). Thanks.

I'm setting up TB for the first time with multiple email and calendar accounts. Some are gmail / google, and others o365.

The primary TB account's calendar doesn't seem to be syncing fully. It's an o365. account. But the email is working.

I added an event on my Outlook for Android on my phone. Its appearing in OWA, and in New Outlook on my computer (so it did sync from mobile Android device to server, and from server to my New Outlook on the Windows desktop). But its not appearing in TB.

Not sure what to check or what the issue might be.

Also, I'd love to replace Outlook Android on my mobile with what I think is K-9. But can't get the same account referenced here to connect to the outbound server.

Welcome any help, and appreciate you all doing this collaborative work.

Computer crashed. After restoring, Google calendar is not syncing. No error message that I can see. I unsubscribed and resubscribed to no avail. I have no clue what to look for and searching here is not helping as all the references to this are years old. Can someone help me figure out why this is happening?

Profiles was bad enough, as Thunderbird can never open the zip file (the wording of the alternative method is gobbledegook, and there are no recognisable files if you attempt to decipher it). At least you can set all your email addresses up manually - you can't physically re-types five years of calendar entries. The infuriating this is that when you start the import, the calendar entries appear before your eyes for up to five seconds and then the program crashes ... again and again and again. I must have been trying this on and off for years now and still nobody has fixed it.

How can I get back to being able to search for an old calendar event of up to 2 years ago, now that a recent Thunderbird update removed that ability and replaced it with the 7 search periods option box to the left of the 'contain' search window?

One of my calendars is not syncing. The same account (O365) also is not syncing the sub-folders.

Not sure what setting may be off.

I added some events from Outlook for Android on my phone sync'd to the same account. But they don't seem to appear, although they are on Outlook Web Access on the browser on my Windows machine.

Information on how to add the Google 'Tasks' into Thunderbird Calendar: I have a gmail imap account using OAuth2 as Authentication Method.

File > New > Calendar, select 'Google Calendar' >  click on 'Next' choose or enter: gmail email address   > click on 'Find Calendars' Select 'My Tasks' and click on 'Subscribe'

You may be asked to enter password as per Oauth2 Authentication.

See image. It shows the selection available when you follow instructions. It shows where 'My Tasks' is located in the Calendar list. I selected 'My Tasks' and then clicked on 'Task'. Create the Task and save. Task is shown in Thunderbird and on the right side you can see the Task is displayed via the webmail access using a browser.

I've been using Thunderbird for work for a few years and a few months ago my calendar integration with my Google Calendar stopped working. I've tried everything I can think of including re-installing calendars, but without success. My Thunderbird at home can still accept invites, but not on my work computer despite verifying that the calendar address and such is the same.

Initially, when I'd click 'Accept' on an invite, nothing would happen (ie no prompt, failure etc), the invite would just stay there without response. Now it's asking me if I want to link it with one of two different calendars I have, both of which I've verified under the calendar on Thunderbird that it isn't associated with an email address (has the yellow bar at the top saying if you want to use this calendar to store invitations you need to associate with an email address).

I can't think of what to do for next steps for troubleshooting, any thoughts?

I'm migrating to a new computer and from Windows 10 to W11. I have successfully exported/imported the contacts using the export tool, but cannot figure out how to ex/im the calendar. I am using a SanDisk drive to move the files. Both systems have TBird 102.1.2 (64-bit).

Please give step-by-step instructions to do the calendar (only) ex/im. I do not use the Mail feature.

I am using the Provider for Google Calendar addon, but have always had the problem that when I flag an item on a Google Task list as Completed then synchronise with Thunderbird, the completion flag stays unchanged in Thunderbird unless I've also done an edit to the task text, or unsubscribed/resubscribed the whole calendar. I was hoping that when Google Tasks got combined/integrated with calendar Reminders a few weeks ago, it might have meant I could uninstall the addon and use Tasks with native Thunderbird CalDAV, but that doesn't seem to be the case. By which I mean, if I uninstall the Provider and try to subscribe in Thunderbird, only my calendars are visible for selection, not my task lists.

Is there a way of exposing the task lists to Thunderbird other than with the Provider, so I can try a way which will sync correctly?

Network calendars no longer seem to be working after upgrade to Thunderbird 102.4.1.

For example, my previously working calendar to this Google vCal calendar no longer syncs. I also had working read/write network CalDAV calendars that are now broken.

I tried deleting and recreating the calendars, but to no avail. Any help would be appreciated.

Here is some output captured from the Thunderbird error console:

Hi, I've searched a lot here and on other websites. I want to integrate the thunderbird calendar with the outlook.com calendar, not the Microsoft Outlook calendar. How to do so? I did publish the .ics file from outlook.com settings but do not know what to do now. Really lost. Please advice. Thanks Mohamed

I'm using an old, no longer supported add-on called Reminderfox that saves its contents in ics format. I used to be able to import this to Google calendar and Thunderbird but for some reason they and also Microsoft Outlook won't now import the ics file. They either give an error as in Thunderbird's case (error, no items to import) or just remain greyed out so I can't do anything else as in Google and Microsoft's case. I have submitted the ics file to an ics verifier online and it says there are no errors. I have also looked at the file in notepad and can't see any obvious errors, although I'm not fully conversant with the ics format. Can anyone suggest what the problem might be or anything else I can try please?
