Thunderbird Community Forum

After an update a few months ago, all installations of thunderbird always open the calendar tab when the program starts. Previously, calendar tab only opened if I opened it (or maybe if it was left open when last shut down, idr now, sorry). This is only a nuisance, having to close the tab each time I start tbird.

I didn't post about this immediately, as I figured others would experience the same issue (or related) and devs would fix the problem. But it has been several months now and this does get to be annoying. I know that merely clicking a close button shouldn't be that big a deal, but I don't understand why this would become the default; moreover, why there doesn't seem to be any way to disable the calendar or at least modify this new behavior.

I've been using tbird for at least a decade and found it to be reasonably simple to use. I use the calendar function, but only for some installations. I would appreciate being able to change the behavior of the startup or maybe just disable calendar altogether where it isn't needed.

Thanks.

I wish to merge TB115 calendar with Google calendar. Do I need Lightning? Do I need Provider for Google Calendar? Confused as Lightning features seem to be included in TB115.

I just updated Thunderbird to the latest version (128.0.1 esr 32 bit), and now a repeated event shows all of the repeats in the list. Is there a way to remove that from the list? I liked it better the old way.

Just updated to Thunderbird Nebula 128.0.1esr on Windows 11 and my calendars are all empty now. I have Google and Exchange (via OWL extension) calendars that have worked flawlessly up until this update, but all show no events in Thunderbird. No other changes have been made and the calendars appear populated in other applications.

Edit: Seems to have fixed itself after a reboot/on a different network. Still 128.0.1

As many have noted, this change eliminates the ability to search for past calendar items. It was a useful ability, especially for interval checking (say, "How long since my last dental hygiene?") but for many other tasks as well. Search of past events needs to be reinstated, if not in the previous manner, then in another - and sooner rather than later.

After updating Windows 11 machine to Thunderbird Nebula, I am asked for a password when trying to subscribe a public nextcloud network calendar. I have installed this same calendar dozens of times on our school staff's desktops, so I know how to do it. I am pretty sure the upgrade broke it.

Hello, I'm new to this Thunderbird I'm using a desktop computer with Win 10 and Office 2016. I have been having issues with outlook 2016, it keep asking for my credentials and I can't seem to be able to find any solutions so a friend recommended Thunderbird to me. I'm trying it and so far my emails are synchronized but not my calendar nor my address book. I cant seem to find where Thunderbird can sync with those two. I do not want to import into the app but sync like my iPhone is doing so if I enter an event in any of them it will show up in the other one. Pretty simple but I can not find this in the Thunderbird desktop app.

please help Kind regards Richard

I have three calendars and if I happen to forget to change which Calendar an event belongs on it will not let me edit that event to choose the correct Calendar. I can edit anything else on that event and I can choose a different calendar but it will not make the change when I Save it.

My Thunderbird profile is on a separate drive.

I had to reformat my computer. No problem with managing profile and all emails and folders, etc are ok. However, my calendar is blank!

Is the calendar not stored in your profile? Have I really lost all my dates and appointments?

Hey guys, the client I work for provided my with MS account to be used for communication. Since I am on Linux, these two things doesn't really bond well :) I was using mostly web access for MS Teams and Outlook OWA ...

However, I figured that I would love to try Thunderbird for at least emails (so I got them all my email at one place)...

After some discussion with client's ITHD (after they changed my license to E3 type) I managed to get the email working - so I can send and receive emails ... However, I cannot see the calendar so it's still almost useless for me for I don't see meeting request.

Any idea how to fix that? did any of you guys face the same?

Hallo ich verwende Thunderbird 128.0.1. Ich möchte einen Termin aus 2023 finden. Das beinhaltet der Filter aber nicht. Wie kann man Zurückliegende Termine finden? Danke im Voraus! Gruß Günter

Hi, Developers have already been notified since the 1st day of TB 128 version release about the problem. The so much appraised calendar in version 115 does not fully function in v. 128. The same old history is repeated. Sth is fixed, then sth breaks or malfunction. We, as users of Thunderbird do not have now the possibility to control all events registered in the calendar. To do that we use other applications then delete the calendar in TB and create a new one. Do we deserve this? Why the new foundation keeps asking us to contribute economically when we never have a fully functional application? (see attached image of Bugzilla records for the calendar issue)

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!

My Thunderbird calendar file is located on my organization's Nextcloud server. We just changed to a newer version of Nextcloud and moved everything to a new url, so my calendar updates no longer work. I need to edit the address of the calendar file. I open the Edit Calendar and can see the old url in the Location field. I can select and copy the contents of the Location field but I can't change it.

See edited screenshot

Thanks in advance for your help.

Hello Thunderbird Team, when I try to change an existing Date in the calendar, I have to delete and insert the Date again, now it's possible to make changes. What can I do to make changes directly ? Thank you Gunther

Hi, I am running TB 115.12.1 without any extensions. I have configured caldav accounts, on Forwardemail servers, on TB as well as on Android with DAV5x. Everything syncs without errors and most calendar entries are visible on TB, but not all!!! I have installed OneCalendar app along side TB and OneCalendar shows all calendar entries (as far as I can tell)!

Has anyone experienced similar issues? Any ideas how I can procede would be v welcome. What are the known issues with calendars on TB115.12.1?

Thx everyone.

Cheers, Adrian
