Hello, I'm wondering why some of my calendars listed under "Other calendars" aren't getting synced.

They are: - Facebook events calendar added through HTTPS URL - some other website's calendar added through Webcal URL - a calendar created and managed by an external app through API

Few other calendars from there, like holidays from various religions, got automatically added. Can I sync them somehow or do they need to be added manually?

Running Thunderbird 115.6.1 (64-bit) on Windows 10. I can add an EVENT to any of my 5 calendars in the dropdown. But when I try to add a TASK, only 4 calendars are offered. Naturally, it's the missing calendar (xxx@gmail.com) I need!

Suggestions would be deeply appreciated.

Thanks, Jeff

When sending out an invite eg for Sat 9:00 The attendess receive it as being at eg., Sat 18:00 or 5:00 when vviewed in webmail. We use icewarp mailserver. When using icewarp mail client or webmail the issue is not present only reproducable with Thunderbird.

Hi, I'm trying to figure out what is the correct procedure (if any) for migrating calendar/task data between different profiles WITHOUT using the UI (since upgrading to version 115, Thunderbird's UI became irresponsive when started with my existing profile , so I'm no longer be able to access my data nor to trigger the export procedure via the UI.

Can anyone point me to the right direction?

Thanks in advance for any answer.

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.

In every version from 118 beta to the latest, the Calendar View Events filter option is limited to max 1 year. In previous versions, there was a filter option to view All events. I need this option in filter to be re-instated because 1 year is not enough. I want to see all events to manage my calendar more effectively.

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

Hello,

I run a. Thunderbird v 78.14.0 (64-bit) on a Macbook Pro 13"mid 2012 with Mac OS 10.10.5 (Yosemite) b. Thunderbird v 115.5.1 (64-bit) on a Macbook Pro 15" mid 2012 with macOS 10.15.7 (Catalina)

How do I make happen, that I sync the calendars in both Thunderbirds constantly, i.o.w. instantly (like for example the iMAP emails do)??

I find the option for new calendars: "On the network" ... Which network is here meant??? In the help there is not much info about it. I am not using and will not use Google or any kind of "social media" (!)

Can I use my own homepage host (which has some webspace left) in order to sync? Or for example an online storage like mega.nz ?

Or could the both macs just sync the thunderbird calendars just via WiFi/WLAN directly (AirDrop ?) or via Bluetooth ??

It would be so great if calendar sync would be as easy as the emails do!

Thanks for you advice!

Best wishes, Thomas

How can the Lightning mini-calendar (upper left) be made to show multiple months (like a whole quarter) Outlook can do this, has for many years. If there is a setting, I cannot find it. Is there an add-on?

Thanks,

Greg

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!

In or around TB 91.3.1 double-clicking on an event, you get a dialog box such as the attached. In order to edit the event, you have to hit the Edit button. In the past, TB would just open the event and allow you to edit it. If the event was recurring then, and only then, would a small dialog box come up to ask if you were editing just this event or all events. I see no advantage to this extra dialog box, especially for one-time-only events. It's just another unnecessary click of the mouse.

TB 102.5.1 (64-Bit), Windows 10 When I want to add a new date or change an existing one, the window does not pop up. However, hovering over the TB taskbar icon, I can see the window as a thumbnail. Very annoying bug, I believe was introduced with the 102.5.1 release.

Could you please assist for that issue: I've updated 91.latest Thunderbird to 102.1.2 and all tasks disappear? I can't make return to previous version of thunderbird 91 where is lightning work properly. However, I made buck up copy of my calendar and I can see all tasks in file, but it's not appeared in version 102.

I cannot see the description for a lot of the events in my calendar when there are large attendee lists. In this example the attendee list is so large I cannot even resize it to see the description. There needs to be a way to scroll the event window as a whole when the content doesn't all fit, or alternatively a way of collapsing the attendee list.

Referring to this archived post, https://support.mozilla.org/en-US/questions/1304213.

I have the same problem - very difficult to find "TODAY" on my calendar. Mozilla - may I suggest highligh of "Today" as an option people can easily set in Calendar settings?

Post reply provides info on changing the userChrome.css, then says to

"Toggle toolkit.legacyUserProfileCustomizations.stylesheets to true in Config. editor"

How/where do I toggle this? Using TB 91.11.0

Thanks, Greg

I had a great deal of items stored on my calendar, some extending close to a year out (medical appointments, etc). Now, since the latest upgrade of Thunderbird a week or so ago, my calendar - along with all my appointments, are gone. How can I get them back? I need them desperately. Please help!

Thanks! Larry S

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've used thunderbird with gmx calendar for many years. Apart from persistently forgetting its "stored" password, I've never had any problems.

But about a month ago, I started getting a message that the servier wants to redirect from the usually-correct https://calendar.gmx.com/begenda/dav/[my name]@gmx.com/calendar to gmx.com.

At first I didn't accept the redirection, but the calendar stopped syncing. Then when I did accept the redirection, the calendar disabled itself altogether. Using the ENABLE button didin't help.

The GMX calendar itself is working fine:

• I can access by logging in at gmx.com and the organiser tab
• the calendar still works fine via my lineageOS phone
• if I go to https://calendar.gmx.com/begenda/dav/[my name]@gmx.com/calendar while still logged in, I can download a raw list of all of my events

GMX support suggested removing the calendar from firefox, changing the password on gmx and adding it up again. Mostly it was not possible to add it, with thunderbird giving the message:

https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-04-16-00-57-44-0e6dec.png

That long location is the location suggested as correct in gmx thunderbird FAQ. But I also tried setting the location as gmx.com or caldav.gmx.com with the same result.

Eventually after trying on numerous occasions I managed to add the calendar again, but in less than a day I was back to getting the redirect message and the calendar not syncing.

I've removed the gmx calendar, reinstalled thunderbird and tried to add the calendar again. At the moment it will not add using any of the locations mentioned above. But of course, I can still access it via gmx.com and my lineageOS mobile.

Also tried adding with thunderbird in troubleshooting mode but no difference.

I subsequently tried two suggested addons (now disabled because they did not help):

https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-04-16-01-13-26-d28ffe.png

• Thunderbird help says 91.8.0 and it's running on windows 10 64 bit.
• I don't have any caldav-related addons (nor did I need any in the many years when gmx calandar was working properly in thunderbird

I do have these addons (but the troubleshooting mode test should have eliminated them)

https://user-media-prod-cdn.itsre-sumo.mozilla.net/uploads/images/2022-04-16-01-19-55-b59057.png

What to try next? I'm only interested in the calendar, not gmx email and I'd prefer to see my calendar in thunderbird than at gmx.com
