Thunderbird version 115.12.2

How can we keep the month calendar visible in the Today Pane?

The option mentioned here seems gone: https://support.mozilla.org/en-US/questions/1420812

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.

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?

After the update to 115.12.2 (64-bit) installed, I made a couple of changes to tasks and TB went sideways and crashed, and continued to crash upon startup every time I restarted, even after a reboot. So, I copied a backup of my AppData\Roaming\Thunderbird directory onto the TB AppData\Roaming\Thunderbird dir. Now TB starts, but I have only Mail and I see no way to get Calendar/Tasks back. How do I do that?

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 can edit and add notes in the description of self-created calendar events. However, invitations are not editable. Is there a way around that, perhaps an extension that you know of? ("Tasks" are not an alternative here for me.)

In the past I had used Thunderbird for both email and calendar for multiple accounts. I just downloaded Thunderbird onto my laptop (PC running Windows 11) and added all of my accounts and they are all synced. However, I can't edit or delete any event from any of those accounts directly in Thunderbird, although if I make changes on a different device they will sync and update properly. I never had this problem when I used Thunderbird before. I didn't see any permission settings that would allow me to do this so I'm stuck. Any suggestions? Thanks!

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.

Is there a solution to a space problem I encounter when printing a calendar in "Monthly Grid" format which includes an event "End Time" that I am unable to find a way to eliminate? I believe that in a previous TB calendar app, there was an option available for that time feature. Is there a work around to achieve my need for not including an End Time in the printout?. Thank you for your time, JMH

I am using Thunderbird Supernova and am pretty happy with it. However, I cannot figure out how to specify a different time zone than the system timezone when creating an event. For example, if I just bought a flight that departs at 4PM London time and I am in Miami when creating the event, how can I create this event without having to convert that time to my current time?

Surely this is possible but I can't figure out how. Thanks for any help!
