Hello- I use Outlook365 at work and populate my calendar with my added events along side my company calendar, which is the main calendar.

 I used to be able to sync this calendar on TB on my personal laptop and got both the company calendar events & my added ones synced on one calendar. Now, all I am getting after the sync is the company calendar and not my added events. Since TB thinks my default email is my personal one, I thought perhaps changing that to my work email would allow the syncing to happen fully. (..this is the kind of thinking you get from a non-computer expert... :-) )

Hello,

For my job I had to create an ics which wasn't the issue. The issue arises when reimporting the ics into Thunderbird. The ics itself isn't broken in some way, I think. I've had someone else look over it and they said it looks fine. Importing the ics into the Windows Calender works perfectly fine also.I don't think that my version of Thunderbird is to old either, I downloaded it yesterday from the Thunderbird Website so it's on version 102.6.1. If it helps there's a error message when reimporting the ics and the error code is MODIFICATION_FAILED. I really don't know how to fix it and it is critical that I fix it soon. Please help. Thank you.

I have noticed that for a couple months now my Thunderbird randomly stops syncing Calendars until I restart it. Changes that I've made to calendars elsewhere are not shown in Thunderbird, even if I press the Synchronize button. But when I restart TB, the calendar starts syncing correctly again.

I am using the extension "Provider for Google Calendar" and three types of calendars: one local, around 10 NextCloud CalDAV calendars and around 10 Google calendars. The problem affects at least the Google calendars.

This is a laptop that is moving around and so the network connection goes down regularly. In addition, some of the calendars are behind VPN so they go offline often. The laptop is also put to sleep mode regularly. I think the problem might be triggered by these events.

I think this is a bug somewhere. My question is, is there some way I could I help diagnose this problem when it happens the next time?

The activity manager list was empty at the time of the problem.

Lightning in Thunderbird works fine with my own Google calendar. On Google I also have read access to my wife's calendar and a public (holidays) calendar, which were both subscribed to in Lightning. Recently both of these calendars have come up empty in Lightning, even though I can still see them in Google.

I therefore tried to unsubscribe and resubscribe to them in Lightning. This appears to be out of date. The illustration doesn't look like what I see in Google.

Nonetheless, by improvising on those instructions, I was able to restore the public (holidays) calendar in Lightning. However, this doesn't work for my wife's calendar. As long as I am logged in to my Google account the URL provided by Google works in Firefox, but no data from her calendar are displayed in Lightning, even though I provided my Google login credentials. Other calendar apps (Apple calendars in iPadOS and MacOS and Outlook calendar in Windows 10) can see her calendar, How can I restore (read-only) access in Lightning?

I'm switching laptops; I exported the .ics file from old laptop to a thumb drive, but when I go to import on the new laptop, after selecting the file, it stops on step 1 and I get the message "No importable items found in the file". I've tried it 3 times, but same problem.

I am importing events from another calendar. This calendar and the events are marked as read only. However, they do not contain any reminders and I cannot add reminders because of the locked status. Is there anyway to add reminders to these entries or remove the read only status? The other alternative is to write a program that regularly writes the current calendar to a .ics file, finds items and creates its own notifications. I really do not want to have to do this. Any help would be greatly appreciated.

I have been using Thunderbird and Lightning on Windows and Linux computers for several years. I just installed Thunderbird 102.6.1 on a new Windows 10 computer. I've spent at least an hour trying to find and install Lightning. I cannot find it. Web searches say to look in add-ons, Tools, the hamburger menu and Events and Task ... not of those exist in my Thunderbird.

How do I find Lightning?

Hi, I hope your day is going well and thank you for taking time to read my topic and question. I'm running Thunderbird 102.6.1, first offered to channel users on December 20, 2022 on Windows 11.

I have a Gmail account with the calendar connected to Thunderbird so, when Thunderbird opens a calendar events is showed on the right. All events are updated since Thunderbird is started but, if as in my case the PC stay tuned on all day and some calendar events are added outside of Thunderbird from smartphone, Thunderbird never update the calendar.

Also opening the calendar with the left bar and try a manual sync never resolve the issue. The only way to update the calendar seems to be exit from Thunderbird and open it again.

Anyone know any solution to have the calendar sync without closing Thunderbird? Thanks in advance.

I have reported this issue in a BUG but I don't expect any help or fix will be done there. https://bugzilla.mozilla.org/show_bug.cgi?id=1809023

I can't "dismiss" my calendar events. Most all events have reminders that pop up--handy. But when I try to dismiss them, the window goes away, but then comes back again within minutes. They NEVER go away.

I've tried to delete the event itself, and it refuses to be deleted. It will disappear from my calendar, but then repopulate, again, within minutes.

I'm running TB 102.6.1 (64-bit) on the release channel (perhaps *that's* the issue...) with Provider for Google Calendar as one of my few extensions (only five in all...). I'm hesitant to disable Provider as that means I get no calendar at all (at least, no Google Calendar).

Ideas?

Hi,

upgrading from TB 91.6.2 to 91.13.0 (Debian 10 to 11) all except one of my calendars are lost or at least not listed in the calnedar tab -> calendar list anymore. It seems that "invisible" calendars are still there: I've changed the password of one according calendar provider and TB is asking for the new one.

I tried the steps under https://support.mozilla.org/en-US/questions/1353231#question-reply but the sqlite query "SELECT * from cal_events WHERE id IS NULL LIMIT 100" doesn't list anything in my case.

Any ideas?

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!

I can no longer view my calendar on Thunderbird. It allows me to put in "new events" and they show up in the daily pane. What do I need to do so I can see my past calendars?

i tried to import a csv file from outlook.com to thunderbird, and all the values are in the wrong fields. E-mail addresses and names of every contact are in the wrong fields. For instance, if I have 100 contacts, I have to edit them individually in Thunderbird after importing the file. This is not helpful. Is there a way to convert the file so I don't have to do this? Please advise.

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.

Hello;

I use TB 102 with the native support for CalDAV server. When I add new account it asks which calendar I want to subscribe - see the screenshot. After configuring my calendar account I received on my CalDAV server access to the new calendars (on the same account). Is there possibility to update a calendars list available for the CalDAV account? As a workaround I add the same account one more to TB (I need to specify user, server, password again) then it allows to subscribe new calendars for specified account. I know that above is possible with TBsync but I prefer to use native support.

Best regards Michal

Hello. I am using Yandex services (mail, calendar, telemost and so on). I have connected Mozilla Thunderbird to my Yandex Calendar. Thunderbird and Yandex Calendar are now synchronized. In Yandex Calendar, there is an opportunity to create online meetings, which are held in a separate APP (Yandex Telemost). The link to the online meeting is automatically inserted into the meeting invitation. So, when I create a new meeting in Thunderbird, it is created in the Yandex Calendar as well. The synchronization functions well. However, I have found no possibility in Thunderbird to create a link to online meetings. Is it possible/feasible to connect Thunderbird to Yandex Telemost? Best regards, Alexandra.

I am using Thunderbird on two Linux machines plus K9 on Android and I'm delighted with the way they all work well accessing the same email account.

When it comes to calendar functionality, the two instances of Thunderbird work well together courtesy of CalDav hosted by my web/email hosting company. On Android, I have a gap. I haven't had a working calendar on my phone since I chose to stop adding entries into Google Calendar.

I have two questions: 1) Does anybody know if Thunderbird for Android will have CalDav calendar functionality ? 2) Can anybody recommend a simple Open Source Android calendar app to fill what is hopefully a temporary gap ?

Thank you

Hi I have been using tasks in thunderbird for a while. It seems to me that Tasks ｢description｣ part use html(with some format), unlike mail body where I can change to pure text.

※reason I have problem with this - If I copy from browser/rich text editor(like word), it brings in extra font - sometimes I need to press ｢Enter｣ twice to add a newline

Thank you

Thunderbird 102.5.1 (64-bit) Windows 11

Since a few years back my Lightning calendar lost all the color backgrounds for categories, which was a plugin that does not work anymore. The small sliver of a color bar on the right side of the event on the calendar page is not helpful to see in a glance what category is coming up in a few days. I have several job categories such as Photography, Video Recording and Audio Job. If I can color code AND SEE them at a glance when I am in the month view is a great help. I am not sure what purpose it serves to have a thin slice of color on the right side of the event! If the whole background of the event line has that color it will serve some purpose. I researched and tried all the css hacks and config edits but nothing seems to work. Is there any help that we can get? I see that others are also looking for a solution that works in the latest version. Any help would be greatly appreciated. Thanks.
