Thunderbird Support Forum

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?

According to thunderbird, this event starts at 10:30 (second image) and runs until 11am (end time is correct.

Google calendar correctly has this event as starting at 10:00 (first image) running until 11am. This event is synced with google calendar and my outlook calendar (outlook has it as 10:00 as well).

It's not a time zone issue because the start time is off by 30 minutes and the end time is right. Any idea what's going on?

(Clearly a calendar sync that gets the times wrong isn't so useful.)

After importing events from the old ics calendar into the existing CalDav calendar. TB sent invitations out to all attendees, even for past meetings. How to avoid this?

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.

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?

I have Thunderbird 115.10.1 (32 bit) and Windows 10 Pro, 64 bit.

The reminder function quit working...nothing at all

I'll add an appointment ask for a reminder, but nothing happens however it used to work

I used to get a reminder email as well as a notice sent to my phone, but now nothing to include the folks I have invited to the event. No reminders for anyone. I have checked Notify Attendees and Separate Invitation per attendee on the Edit Event pop up the by nothing I do seems to work.

The goal is to get the reminder to the phone screen(s) and emails.

Many thanks as I'm lost on this one

Thanks!

Hello! I am facing the issue with time zone translations. Here is what I do. First, I create event on web-interface of the google calendar. That account is linked to TB's calendar. This calendar has settings for my timezone as in the first screenshot, that is GMT+3 for Kyiv, Ukraine. It is actually GMT+2 + daylight saving hour in effect. Country is also set to Ukraine. Next, my Windows 11 system is set to set time and timezone automatically, region - Ukraine. It displays UTC+2 Helsinki, Kyiv,... I guess it's Windows settings display quirk, because time is correct and WSL console shows

~$ date -R Thu, 18 Apr 2024 18:59:25 +0300

My TB's calendar is set to have system's timezone as in 3rd screenshot.

Now if I see my event in TB calendar, it is placed one hour later, say 9 am event starts at 10. So reminders also come hour later. Also strange thing is that event properties in TB show correct time like 9:00 till 10:40, but for some strange timezone Europe/Zaporozhye, as in 4th picture.

However, if I set TB's calendar manually to Europe/Kiev (which should be Kyiv, but that's another story), then events are shifted hour up to their right place, 9 am. So this is my issue: when I set calendar forcibly to Kyiv timezone, it does translate it right. When I ask calendar to rely on system's timezone, which indeed is also Kyiv, then I get one hour behind.

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.

Since updating Thunderbird to 102, I can no loger import the lightening calendar. Exporting a .ics file from one pc works but on trying to import it into any other pc or the same one, I get "No importable items found in the file". Any help would be appreciated.

Hello first sorry if this has been posted before and I missed it.

Been looking for an alternative email client since Microsoft is changing over to their clunky web mail app in windows.

Been trying out Thunderbird (version 115) added my Outlook/Microsoft account which works fine email wise but the calendar does not show up. I can add the same account or my google account to say EM mail or mailbird and the calendar shows/syncs up s in those programs effortlessly.

Does this not work the same in Thunderbird or do I need some extra plug ins? I seen trying to share and export the ics file but I just want to sync it like any other program.

Thanks for your help

When I enter an event on Thunderbird, it is immediately reflected on my online Google Calendar. However, when I enter the event on google calendar website, it does not automatically appear on my Thunderbird Google Calendar. Don't understand this. The only add-on I have on Thunderbird is the 'Provider for Google Calendar' (to allow bidirectional access to google calendar). I don't see any settings to fix this. Help! Note: It updates when I press 'synchronize' on Thunderbird, but I don't want to have to remember to do that. Should be automatic!!

Since TB 115, I have issues with the "invite" functionality of Lightning, as follows.

It generates errors as follows:

• "invite" does not work. I can add emails to be invited to an event, but the invite is then not sent at least with the option "notify" + "send individual mail" (other alternatives such as open visible list of destinatories are not feasible due to privacy)

• when opening an "event" from the calendar, it displays in a full-screen format (see screenshot_2) that lists all invited attendees

• The "invite attendees" window works but has a strange pink block on top right (see screenshot_3)

• the page where the format of sending ("notify", "send individual mails") is not accessible any more

Currently the calendar as such works fine. But the "invite" function is critical for the use I am giving as transnational NGO to invite to meetings etc. All worked fine with previous TB versions.

System config: WIN10 prof, all updates installed, fully licensed, AMD Ryzen 9 5900X etc. (mid-end system built in 2022).

Thanks for looking into a solution.

Just a couple of days ago, Google calendar no longer syncs with Thunderbird. I didn't change any settings and it looks like I can't even re-add the Google calendar events it should sync to.

Hi, I use new version 115.1.0. When creating calendar event and adding attendees, they don't get the invite and I don't see the message that sent in sent items folder. Please assist

I recently upgraded (and then downgraded) to 102 release but was very disappointed to note that the release disables the very useful WebDAV and tbsync add-ons that are mission critical for me to sync my calendars from my hotmail and google accounts in and out of Thunderbird. These work great on TB 91 release and I had hoped that the new release will either provide support for various calendars (Google and Microsoft at the very least) out of the box or preserve the calendar sync support using the existing add-ons at a minimum.

Is there a way to make these calendars sync in Thunderbird 102 release? If so, please help. - Thanks a ton!

I had a big event related to security on my ISP last year and I moved my calendar and contacts to an internal cardav and caldav server in my hosted Synology NAS. I was able to setup Thunderbird well and I did assigned a calendar identity to the calendar with local management of the invitations. In the configuration, it correctly shows, as in the article (https://support.mozilla.org/en-US/kb/enable-email-invitations-caldav-servers-configured) that I prefer Client side email scheduling and I have assigned one of my email accounts. The problem I have is that when I create a calendar entry and state that I want to invite people, by default it states that the organizer is otto.acuna@local.host, not the email identity I assigned and that it shows in properties

Any ideas if this is something I need to edit somewhere internal? Thank you in advance for your help Otto

As mentioned in title I cannot use the calendar function at all. Same with tasks function:

• I can open the calendar tab, but that's it.
• There is no calendar on the calendar list, and the 'plus'-icon to add a new calendar is greyed out.
• There are buttons to change the views (week, day etc) but these also are greyed out.
• Same issue with tasks: I can open the tab, but cannot add any tasks

It all worked with older versions of TB. I had several calendars in place, no problem. But after some upgrade everything is gone. The calendars, originally set up on TB, are still there, but only accessible on the g-account...

Version: TB 91.11. Add-ons: Provider for google calendar

Any idea? I really want to use TB calendar function instead. If I could at least only set up a new calendar, that would be very helpful. Thx a lot in Advance!

I am using older Thunderbird 102.x due to newer version having an issue. The Search tab contains "Find Events" input area, where i can search all Events, but not Tasks. Which is weird and wrong IMO. I always assumed that it search everything in calendar. So how do i search also Tasks or how to convert all to events?

From the beginning i was not told the difference between the Events and Tasks, it is not enough intuitive for me to differentiate the two. https://superuser.com/questions/1321548/thunderbird-add-on-lightning-what-is-the-difference-between-event-and-task

Its just not there as an option. All the tutorials I see say to select caldav... Its just not there. I enter the caldav URL in case it now "Autoselects" (No tutorial I can find says it does) and it can't find any calendars, so I am assuming something is wrong/missing/messed up somewhere.
