This BUG has persisted for over two years. Reiterating this question/bug report since it is a constant irritation and for which there was no response previously...

With all the various iterations of the TB Calendar including the latest (currently 115.10.1 - 64bit), it has always been a mystery as to how the organizer email address is selected when creating a new calendar item with invitees. It seems to be somewhat random and it changes for no apparent reason.

In my context I show three calendars, all remote (fruux, CALDAV). All three are configured with usernames and email addresses appropriate for the calendar.

There are two fields in an external calendar properties settings that might apply: Username - the email used to access the external calendar....Not appropriate to use for the 'organizer'. Email - according to the documentation "This is the email address Thunderbird uses to send invitations for events." This would be appropriate as the default organizer but it isn't what is used. Instead the Username email is used. THIS IS A BUG.

One would expect that for a calendar item created, when inviting attendees, the organizer would be the email address configured for the calendar but this is *NOT* the case. Instead, it seems an address is plucked somewhat randomly and applied to the field.

Is this something that can be configured or is it just a BUG? It is painful to have to constantly correct the organizer email and results in confusion with my meeting participants, especially when the invitation arrives from a strange email address.

Note that with upgrades to TB 115 and beyond I completely replaced my TB profile from scratch and the problem has persisted across the profile rebuild. So that does not seem to be a solution to the issue.

I'm unable to connect Thunderbird to my icloud calendar. I was able to locate the calendar url through my icloud account, but I could not get the set up process to recognize my password. I tried using my icloud password, my email account password, and the app specific password for my email server. Not sure what else to try.

Now that the sync add-ins have been obsoleted and removed, my calendars no longer sync. What do I need to do to ensure two-way synchronization between Thunderbird's Lightning calendar and my iCloud calendar in a post-TBsync universe?

Thanks!

Hi, I know there is reminder to Play a sound , but if I'm away on the computer and I come back, I will miss it. Is it able to have bring the email window To Top when reminder is triggered?

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.

Background: I have two PC's accessing profiles and data on an NAS device. Automatic upgrade to TB 128 went fine on laptop, but on desktop (which installed after laptop), TB did not find the desktop profile (I think--it displayed the create a new account screen when it started). I manually added accounts and pointed them to Local Storage location on NAS. Had to re-enter some settings (e.g. incoming email notification), but all seems okay on email side.

However, my calendar and tasks do not display. I use a local calendar, plus Google, which was not showing in 128. Added Google and it works fine, but local events and todos do not display. I located the local.sqlite file in my desktop profile and viewed it with DB Browser utility. I can see tables and I can find both event and todo data. I restored a backup from before the upgrade, but still no events/todos in TB (the backup file shows events/todos using the utility).

Any advice on next steps to fix this? Thanks.

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

Is there a way to create an Event / Task in Thunderbird Calendar so that it is in a box which I can assign a color to for each event (T-Bird.jpg). I have attached a screen shot of what I would like to do vs how Thunderbird looks now. (T-Bird 1. jpg.

I recently switched to Thunderbird calendar and I really like it but I have just one question to make my calendar perfect.

When creatingan Event / Task Is there a way to isolate each Event / Task in their own box and fill color sollelction? When I go to print the calendar all that I see are the words. If I could color the boxes as I have done in the attachment (T-bird)from another calendar that I use to have, and the other attachment is printed from Thunderbird (T-bird-1)and it it would make it easier to see with bigger fonts and colored box.

Until I tried to set a task 5 minutes in size (I am logging timeboxing rather than setting things in advance) and the visual block had a minimum size that made it overlap even though the times don't (had this issue super heavily with google calendar, thought this could be the saviour but ig not). I'm not a C++/JS programmer I only know lua, html and css so I could take a look at the source code but I've also never built anything and I'm not sure if this will be as easy as tweaking a value.

If anyone has expertise and it doesn't take them that much time I would appreciate it if you could send a build where the event block can be visually any size you set it to. Thanks either way

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 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.

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
