Thunderbird Support Forum

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 OS is Linux Mint 20.3 Una base: Ubuntu 20.04 focal Thunderbird version 102.4.2 (64-bit) "Today" marker does not advance to current calendar day after midnight of the previous calendar day in monthly view. The monthly view is the only view I use. If the < Today > link at the top of the calendar is mouse-clicked, it does not advance to the current day but remains on the previous day. To advance the day marker I have to click either "<" for previous month or ">" for the next month and then click Today. At that point the calendar will return to the current month and highlight the current day. This problem was also present on a previous version of LM (18.3) My add-ons are: Cardbook v. 83.6 ConfirmBeforeDelete v. 1.7.0 Lightening Calendar Tabs v. 2.8 Provider for CalDAV & CardDAV v. 4.3 TaskviewFlexLayout v. 62.9

There are two disabled extensions which could be uninstalled as they have been disable "since dirt was young,": TabAddressBook ToDo.txt Both were automatically disabled by Thunderbird due to incompatibility and I have no further need for them The active extensions are used with regularlity. This is a "livible" problem but but an irritation. Searches with multiple search engines have turned up nothing on this issue since 2020 and/or v. 68 of Tbird. Thank you in advance for any assistance you may provide on this issue. Mozilla software has bee my default software of choice, also "since dirt was young," and for what it's worth (which is very little) I check viable alternatives virtually every six months to see what your "competition" has to offer. Particularly, your configurational granularity is STELLAR! Once again, thanks!

It's a pity that we reached version 102.1.2 and till now a common problem has not been solved. In email composing window when misstype a word there is the red indicator for mistakes and then by right clicking we get the correct proposed words. In event creation we get only the red indicator for mistakes. Nothing more. It's a pity a so much advertised version to lack such a basic feauture.

Events on external calendar created before 102 update all show, or did, I assume to due to Offline Support, but updates, changes, new events added since were not syncing, and after Unsubscribing and attempting to re-add the ext. calendar, Thunderbird is not able to 'find' the calendar at all, I just get a spinning ball.

The same external calendar is successfully being found and updated by another service. I use a Mac.

I am not sure if I am using the correct verbage but here goes: When I launch Thunderbird a panel opens in the upper left with all events that are in the past and not yet dismissed and all events for the current day that are not dismissed. I was in a hurry and instead of minimizing it I clicked the red x in the right upper corner. Now it does not dislay on startup and I cannot find a way to get it back since it has been there since I installed Thunderbird. I believe the correct name is Event Preview Pane but not sure. Any help is greatly appreciated.

Running Thunderbird 115.8.0 (64 bit) on Windows 11.

Until recently all was working well accessing an outlook.com calendar (on server outlook.office365.com) using tb-sync and Provider for Exchange ActiveSync (latest versions).

Now I get the following error: "Could not authenticate, check username and password (HTTP Error 401)." (Meanwhile email is working fine with the same credentials).

I then tried using the new Thunderbird non-add-on exchange calendar integration, with identical results.

I then deleted all the cached outlook passwords (settings -> Privacy and Security -> Passwords -> Saved Passwords) and tried again, with identical results.

Interestingly, after deleting the passwords, closing and reopening Thunderbird, it successfully downloaded new emails from outlook.com (in spite of supposedly not having the passwords).

Help please.

Dear all, I have a couple of calendars on the disk as network calendars (file:///...ics) with offline support, and I just realized that I cannot delete any event. These calendars are not read-only, I can see the option delete, both with right-click on the event and double-click to edit the event, but after pressing delete, the event remains on the calendar. Just pressing the delete button on the keyboard after selecting the event has the same behaviour. If I try shift the events from one calendar to the other, they do appear in the new calendar, but they do not disappear from the old. I have restarted Thunderbird, and also tried this on another computer with the same results. Both szstems are Windows 11, Th underbird 115.10.1 I would be very grateful for any suggestions

Have just been updated to v102.2.2 and now my events are invisible in the weekly calendar view, though they are visible in the multiweek view. Also reminders are not being actioned.

Can anyone solve this please?

I'm using Windows 11 on a Dell Inspiron.

Greetings - since using T-bird calendar for several years now, there is a recurring bug that is most annoying. On a regular basis, the calendar preferences reset to Monday start which has created some meeting/scheduling issues. Please fix this.

Hi there,

the event time selected during event creation has the 24 hrs format I want, but the calendar after it has been created shows it with 12 hrs format - see the uploaded image: is there any way to fix it?

I'm running Thunderbird 102, 64 bit, fresh installation (not upgrade) on Win 10.

Thanks in advance.

Hi all, I work for a Company in north Italy, and we use Thunderbird, before the update we used Thunderbird version 102 and everything worked fine but now after updating, when a calendar entry is made and you add participants they won't receive an invite but will still see it in the calendar itself. I've looked for some options and found this: " https://support.mozilla.org/en-US/kb/enable-email-invitations-caldav-servers-configured " " https://support.mozilla.org/en-US/questions/1309527 " I tried them but the option is still grayed out is there any way to fix it without changing our SMTP server?

Hi,

I am running Thunderbird 115.6.0 on Linux.

One of my calendars is on a Synology NAS with Synology Calendar.

I can create new events. As long as I don't close Thunderbird I can change the events as well.

But after a restart of Thunderbird I cannot change the events anymore. Ending up with a o/rjcpdo/pdo/faa15765-29e1-4470-80d7-5157b042bddf.1705244573723.ics [HTTP/2 405 Method Not Allowed 817ms].

I can still change the event for instance on the default calendar of Android. The changed events also show up in Thunderbird.

After changing the event on Android. I can change the event in Thunderbird again untill restart.

What I've seen so far is that the working link from Thunderbird is different than the link when it is not working. Not working. https://XXXX.synology.me:80/caldav/xxxxx/rjcpdo/pdo/faa15765-29e1-4470-80xx-5157b042bddf.1705244573723.ics

working: https://XXXX.synology.me:80/caldav/xxxxx/rjcpdo/faa15765-29e1-4470-80xx-5157b042bddf.1705244573723.ics

I've changed part of the link (xxxx) but it is the extra pdo part in the not working link.

Anybody any idea what is going wrong here?

Regards

I can no longer see the .ics files that were once used. There are some sqlite files but they are unintelligible to me.

I would like to be able to read calendar entries, without modifying anything.

Would someone please point me toward any documentation, or advice.

Hello I am having issues with my calendar option not retaining the events that I have entered. I have never had this issue before. I have no clue how to get it to retain the entered events. Any direction would be greatly appreciated. Thank you! Monique

I am affected by this bug in Thunderbird 115.6.0 on Debian Linux (KDE xorg) so I cannot currently use two-finger touchpad scrolling to navigate without flying months into the future or past. On top of that, there is no visible scrollbar and it is not even responding to the keyboard arrow keys or PgUp/PgDn when the focus is on the main calendar. Any idea how to get this working? This is making it pretty impossible to get around when I'm not using a mouse with scroll wheel.

Hi guys.

I have a small problem that I'm trying to solve. I'm in Linux, but unfortunately, I still have to work with MS outlook, in VMWare, because Thunderbird have a lack of functionalities comparing to MS outlook, and I cannot live without these functionalities. I manage over 100 complex calendar notes per day, with attachments (e-mail attached, images, and other calendar notes attached).

The following functions could increase the functionality of thunderbird if they were implemented: - Select several notes at the same time, to delete them, or to Drag and drop to another hour or another day, just by releasing the notes in the day using the side calendar (that has the number of the days) or releasing the notes on the day visualizer; - Select several non contiguous days using the function key CTRL (example, day 3, 8 and 15), to view them side by side, and/or to drag and drop calendar notes from one day to another; - Ability to add attachments to calendar notes.

I'm really looking for a management of the calendar, similar to Microsoft Outlook, but I don't want Microsoft, I want open source.

Do you guys know if there are plans to implement these functions in any near future?

Thanks in advance.
