This continues to be a problem in version 115.12.2. It seems to happen only with older events rather than current ones. Clicking the X closes the reminder but it pops up later. I tried changing the event to turn off reminders but that didn't work. It doesn't accept the change. The only permanent solution is to delete the event from the calendar. I see this problem goes back many versions. It's time to fix this.

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?

My calendar screen stretch blank screen to the end. If I use 2 screens it is better. It still stretch through second second. Bu I still have Monday, Tuesday and Wednesday. The rest is gone.

The problem go away when I use troubleshoot mode.

Please help me and give me advice.

Regards, Harris

Thunderbird 115.6.1 (32-bit) on Win 10 and Win 11, local calendar, no email invites are sent to the listed Attendees. Correct email is entered on Calendar/Properties/Email and Notify attendees is ticked on New Event dialogue. Attendees are correctly entered under New Event/Invite Attendees. After clicking Save and Close, there is no Invitation email record in "Sent" emails and the Attendees do not receive email invitations. The event *is* saved in the originator's calendar.

The invites were correctly sent on the Win 10 PC up until TB version 113 (?), when they stopped working after the update (I think). Eventually email and calendar data were transferred to a fresh TB installation on a Win 11 PC, but the invites are still not sent.

The only difference that I can see between this non-email-invite-sending version of TB on a WIn 11 PC and another Win 10 PC where the invites are sent, is that "Troubleshooting Information/Force Email Scheduling" is set to true on the non-working version and is blank on the working one. Clues where to look next?

We've just started having an issue with Thunderbird continually prompting for Calendar passwords, but not remembering them. IMAP and SMTP seem to be retained ok. Additionally, if we just skip past the prompts (we are using around 5 different calendars), and just go and click the "Enable" button....they open just fine and we don't get any prompts, until we close and re-open Thunderbird. We're running 115.12.1 on Windows 10, 11 and Server 2022 Datacenter. It's not a devastating problem, but a little tedious for some of our users that open and close their Thunderbird a lot during the day. We are running "Smartermail" V8909 from Smarter Tools as our mail server. Thanks in advance!

Hello! I have linked my smartphone with the add-on: Provider for Google Calendar. How can I now transfer my existing appointments to the Google Calendar? I tried to export the existing appointments and then to import it into Google Calendar. Unfortunately, this was not possible because not a single appointment from the existing calendar is exported. I just get an empty .ics file. Any help? Please! Martin

I invited someone to an appointment, but screwed up the repetition parameters. I then cancelled that appointment.

The person I invited accepted the original (screwed up) appointment but did not process any emails to cancel the meetings. How can they edit / delete appointments that they did not themselves set up? You can see how messed up the calendar is with the erroneous entries...

My calendar stopped syncing one way: when I add an event in Thunderbird, it does not appear in Google calendar. It worked fine until about a month ago. I am using version 115.11.1

I am running Thunderbird 115.11.1 on Windows 11 and no matter what I do I simply cannot send a calendar invitation. I click to create a new event, I add the email addresses of the attendees, I make sure to click the checkbox to send out invitations and as soon as I click Save and close nothing happens other than the addition of the event to my own calendar.

Yes, I have checked whether my email address is included in the calendar settings. Additionally, there is nothing in the Sent folder after clicking Save and close.

I'm using thunderbird 115.10.1 on Ubuntu Linux. I've set up a second calendar and associated it with an email account hosted by Polaris Mail. That email address has worked fine within thunderbird for everything else for a long time, but I only recently associated it with a calendar. When I get a meeting invite, for example from a gmail user, and accept that invite, selecting "send a response now", no message ever arrives at the email of the inviter and no email ends up in any of my folders (drafts or sent). It is like nothing happens. The event *is* accepted and added to the calendar, but no respose is created or sent. I have another email account and calendar and meeting acceptances and responses seem to work fine.

I've looked at all the settings I can find and they seem appropriate and analogous to those with the working email/calendar. The correct email address appears in the calendar properties opened by right-clicking on the Calendar and selecting properties.

Any help? Thanks.

In Outlook you can forward an appointment that is not created by yourself to someone else. In Thunderbird this option seems not available, or is it? Adding attendees to an event that you did not create yourself does not work.

Hello,

I'm kicking the tires on this and the biggest obstacle for me right now is that when I view the calendar in a week view, the day starts at midnight. I would like to hide midnight to 6am.

I followed these steps, that did not work:

1. Navigate to the hamburger menu in the upper right corner. 2. Select settings. 3. In the calendar tab, I changed day starts to 6am, and day ends to 9pm.

There is no way to save this, so I assume it just works. However, when I navigate back to the calendar, nothing has changed. The day still starts at midnight.

Am I possibly looking in the wrong place? Is there a way to customize this as I've described?

Thanks for any help.

I have a Google Calendar, in which I manage My Tasks. I can't see my existing tasks in Thunderbird, and I can't add new tasks to the Google Calendar. New Task in Thunderbird is greyed out and the field next to it has the writing: "Please select a calendar that supports tasks".

I have seen that many had the same issue and understood that it is linked to how My Tasks in Google Calendar itself works. Is there really no workaround whatsoever?

If not, how can I manage tasks and share them with someone else (who uses Google Calendar or Apple Calendar, but does not use Thunderbird)?

Thanks in advance for your replies!

I have Thunderbird version 115.5.1 installed on my Windows 11 laptop. I have logged into my gmail account and subscribed to google calendar. I have turned the off default reminders for events and don't have any extensions installed, but when I create a new event and select "No Reminder," Thunderbird automatically sets a 30-minute reminder. I can modify the reminder by editing the event after saving, but I can't directly create a new event with no reminder.

Hi,

Scenario: I have a custom domain with an email address, and have used mailbox.org and currently icloud to host my email. In both cases, the email address associated with my custom domain is the only one I use for everything, such as email, calendar, contacts, etc (x@er.com). Also in both cases, there is also a login email address to the email hosting service (i.e. x@mailbox.com and x@icloud.com respectively).

Issue: My calendar invites erroneously send from my icloud email address, rather than my custom domain email address. This appears to be by defaul and unchangeable. See 1/2 screenshot.

Settings: I'm on W11 Pro, using TB 115.10.1 (64-bit). For calendar settings, see 2/2 screenshot.

Background: With both providers, my calendar invites initially were being sent from the correct email address (x@er.com), but inexplicably switched to the being sent from login email address of the email hosting service after some time (about a year with mailbox.org, and a couple of months after migrating to icloud.com). This messes up my calendars, and I need to resolve it. Hopefully it's just something dumb that I'm doing.

What I've tried: On mailbox.org: When the issue first occured I put up with it for a few weeks then assumed it was probably mailbox.org and migrated to icloud. This appeared to resolve the problem at the time. On icloud, my calendar sync was setup in TB using add-ons, which worked for a couple of months and then the issue recurred. I've tried: 1. In apple account settings: I tried changing my apple-id to be my custom domain email address, rather than my icloud email address (didn't fix it). 2. I then unsubscribed from all of my network calendars in TB, removing the addons and restarting TB, as per https://support.mozilla.org/en-US/questions/1406255#answer-1568028 - I had to add a blank local calendar first before I was able to remove all of the network calendars. 3. I then added my calendars back into TB by using the direct URL locations, as per https://support.mozilla.org/en-US/questions/1406112 - when adding the calendars back, I tried using the login as both my custom domain email address, and also my icloud email address (didn't fix it).

Any help would be much appreciated.

Thank you.
