Thunderbird Community Forum

Have used the calendar feature for years. After update to 102.4.0 (from openSuse) the calendar pane is not visible. The "Calendar" entry in the View menu is greyed out. Don't see anything like this in search of the forum. The calendar tab is present, and I can see events. Is the pane gone, leaving the tab? Thanks.

Network calendars no longer seem to be working after upgrade to Thunderbird 102.4.1.

For example, my previously working calendar to this Google vCal calendar no longer syncs. I also had working read/write network CalDAV calendars that are now broken.

I tried deleting and recreating the calendars, but to no avail. Any help would be appreciated.

Here is some output captured from the Thunderbird error console:

services.settings: Failed to load last_modified.json: TypeError: NetworkError when attempting to fetch resource.

When adding a future date event from the Lightning calendar Today Pane (with mini-calendar displayed), I click on the date when I want to add the event, then click the New Event link below the calendar. This brings up the New Event dialog, but the dates in the Start and End fields default to today's date, not to the future date I selected in the Today Pane, so I have to re-select the desired date in those fields. In older Lightning versions, those preselected dates used to default to the date I selected in the Today Pane, which is obviously when I want to add the event. Is there any way I can get this old behavior back in the current version (102.2.2)? If not, I'd like to request that this behavior be added, or at least have the option to be added, in a future release. Thank you for listening.

Hi team

I notice an interesting difference in TB's version 102 compared to the former version 91. This is running on Ubuntu 22.04 and at the backend there are only CalDAV based calendars (no local calendar defined). I am using the Today pane with the calendar's upcoming events in the upper part and the tasks below.

When adding a new task via the "click here to add a new task", choosing the name of a new task (i.e. Test3), there is no indication that the task has actually been added. It is not showing this new task in the pane at all (which is clearly different to TB version 91 where that new task appeared in the list).

If I open the task window (tab), I can see the new task is there but I won't see it in Today's pane. In the task window (tab) view I have chosen to show the name of the calendar where each task has been added to and the newly created task is shown in the correct (CalDAV) calendar. The (test) tasks created show a default start date (today 8am) and end date (tomorrow 6pm).

The tasks will eventually appear in the Today pane but I have not paid attention when exactly. I know that they are there next morning when planning my day but right now when testing, neither a manually initiated calendar synchronisation nor even a full Thunderbird restart will show the task. Trying to work in the pane (i.e. change sort order) to do some kind of refresh for the pane does not show the new task(s) either.

Thanks for reading.

Hi,

Please explain how to open SHARED Google calendars (that I do not own) in Thunderbird 102.4.0 on Win 11 Pro. Here is what I have tried:

(1) Added Google Provider add-in. Attempted to add my Google Calendars. It didn't find anything at all. (2) Removed Google Provider add in. Attempted to add my Google Calendars. It added the ones that I personally own just fine. However, it did not detect my husband's shared calendar to which I have view-only access. Interestingly, it DID add a shared calendar to which I have read/write access. (3) Restarted Thunderbird. Attempted #1 again. Attempted #2 again. (4) Restarted Thunderbird. Attempted #1 again. (5) Restarted Thunderbird. Attempted #2 again. (6) Restarted Thunderbird. Attempted #2. Then attempted #1. (7) No change in results. (8) Swore at the application multiple times. (9) Hit up these forums. Found that I am not the only one with this problem. Attempted to find solution. It was written in tech-ese and not English.

Please explain -- in English -- how to add view-only Google calendars, that I do not own and to which I do not have update access, to my new Thunderbird installation on my new computer. All I am trying to do is view my husband's calendar.

Thank you.

This issue started happening recently. I am using Thuderbird 102.3.1 on Linux. I have recurring events in my Calendar. After the event date passes, I still get the notice with date "Yesterday at ..." When I dismiss the event, nothing happens, it persists. I've cleared my error console, then tried to Dismiss again and I get this in the error console:

CalDavCalendar.jsm:757 NS_ERROR_FAILURE: Server Replied with 400 calCachedCalendar.js:747

What can I do to dismiss these events?

My calendar is suddenly a day behind on all of its dates, and the time for adding an item to the calendar is off by an hour. Is this just my computer (MacBook Air), or are others having this problem too?

Hello,

My email host (Epik) recently removed their calendar server, hosting9.epik.com, and switched it over to a new URL. I removed all my network calendars and saved passwords for hosting9.epik.com, and added the new calendars with the new URL. However, every few minutes I get a pop-up (four, actually, one for each calendar account) asking me to provide my credentials for hosting9.epik.com. Of course my credentials no longer work and these modal dialogs block progress until they are all closed via the "X". This process repeats every few minutes and makes Thunderbird virtually impossible to use.

Can you please help me remove any/all references to hosting9.epik.com in my Thunderbird settings? I have removed the saved passwords and calendar accounts, and none of my email accounts' servers (IMAP and SMTP) refer to hosting9.epik.com. If there is somewhere else to look, please let me know. Is there some settings file I can edit on disk to remove these references, that are not available via the GUI settings? If not, I fear this may be a bug causing Thunderbird Calendar to connect to deleted servers.

Thank you!

Have not found a way (yet) to sort or filter my Lightening Calendar Events by an assigned "category ID".

I've also not been able to find an extension or add-on that may address such a capability.

For example: I have a series of medical appointments scheduled throughout an upcoming year or any time-frame. I would like to be able to sort or filter on the category ID that I've created for those appointments.

It is likely possible that I've overlooked an obvious option or even add-on, but so far No Joy.

Creating a "Task" is a possibility, but Tasks will not appear in the Lightening Calendar display.

Any suggestions please?

When I install Thunderbird 102.1.2. (64) on my Windows 10 PC and install a calender (via net) with a link to my Synology DS220j NAS. Thunderbird shows a turning wheel for hours. In the task manager the "inbox" seems not to run. From then on, I get always the turning wheel when I start TB. I could stopp this by deleting the directory "calender-data" in preferencies and delete the Synology-Calender in TB afterwards. I see this behavior on 2 PCs. The Synology Caldav works fine with Outlook and some Androids. Has/had anyone the same issue and a solution how to manage it?

I'm migrating to a new computer and from Windows 10 to W11. I have successfully exported/imported the contacts using the export tool, but cannot figure out how to ex/im the calendar. I am using a SanDisk drive to move the files. Both systems have TBird 102.1.2 (64-bit).

Please give step-by-step instructions to do the calendar (only) ex/im. I do not use the Mail feature.

I have followed all of the instructions by Toad-Hall (as far as I know ) for making categories in my calendar different colors (instead of the small bar at the right).

I have made sure that the legacy is not false I have opened Profile, added folder called chrome, copied the text given into folder called userChrome.css (this was saved as txt, which I changed to css).

I then started Thunderbird and still find that I cannot get full color in my events.

What have I done incorrectly? (I am on a Mac running Big Sur). Thunderbird version is 91.12.0

Thank you for any help.

This morning when I opened Thunderbird all entries that have other participants invited have disappeared. The entries without other participants are still there. I am not aware of an update. I can create new events and invite people. It seems the data is just gone somehow, and I somehow need it back.

OS: Ubuntu 22.04 Thunderbird: 91.11.0 (64-bit) How to reproduce: no idea

Since upgrading to v102 I've lost events in my calendar and am progressively losing historic data that I wanted to keep (events that were there last week aren't there this week). I've tried copying a backup of local.sqlite and checked the entries in prefs.js to no avail. If I can't fix then I'm going to have to dump Firefox and Thunderbird.

Since upgrading to Thunderbird v102 on my Mac I've lost events from my Lightning Calendar. I seem to have lost all my bi-weekly or monthly repetitive events (my one-off or annual repetitive events seem to be in tact).

I've tried closing the calendar and restarting Thunderbird but all to no avail. I was wondering whether I might restore my Lightning Calendar from my Time Machine backup (before I updated to v102) and, if so, what files I might need to replace.

With the update to release 91.13.0 the icon to open the calendar disappeared from the tool bar. The icon is now located above the search box. How do I get it back to where it belongs?

Information on how to add the Google 'Tasks' into Thunderbird Calendar: I have a gmail imap account using OAuth2 as Authentication Method.

File > New > Calendar, select 'Google Calendar' >  click on 'Next' choose or enter: gmail email address   > click on 'Find Calendars' Select 'My Tasks' and click on 'Subscribe'

You may be asked to enter password as per Oauth2 Authentication.

See image. It shows the selection available when you follow instructions. It shows where 'My Tasks' is located in the Calendar list. I selected 'My Tasks' and then clicked on 'Task'. Create the Task and save. Task is shown in Thunderbird and on the right side you can see the Task is displayed via the webmail access using a browser.

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.
