Since updating Thunderbird to 102, I can no loger import the lightening calendar. Exporting a .ics file from one pc works but on trying to import it into any other pc or the same one, I get "No importable items found in the file". Any help would be appreciated.

I recently upgraded (and then downgraded) to 102 release but was very disappointed to note that the release disables the very useful WebDAV and tbsync add-ons that are mission critical for me to sync my calendars from my hotmail and google accounts in and out of Thunderbird. These work great on TB 91 release and I had hoped that the new release will either provide support for various calendars (Google and Microsoft at the very least) out of the box or preserve the calendar sync support using the existing add-ons at a minimum.

Is there a way to make these calendars sync in Thunderbird 102 release? If so, please help. - Thanks a ton!

I want to submit a feature suggestion for Thunderbird, but I don't know where to put it.

My idea is that we could name each reminder for the event and that way we would know which reminder has just gone off. If you have 3 or so reminders for each event, then when the event appears you don't know if it's your day before, 2hrs before 1hr before etc. It also means that you can't write something like "that event is tomorrow" or "leave in 1hr" for example. So I would like to be able to name each reminder.

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

Hello, I've had massive problems with it since the update to Thunderbird 102 and the migration of the Google calendar directly into Thunderbird. Appointments are not created, I cannot write an appointment description or it is not saved and transferred. Often an exclamation mark appears after the calendar name in the calendar overview, it is not synchronized - unfortunately it is so very difficult to work with it - or otherwise, even almost impossible. Are there other reports with problems in this direction or is it my system and the settings? I would be very happy about help or tips, many thanks and best regards Ps. is the help also available in German?

I have installed Thunderbird 102.3.0 with Lightning Calendar Tabs but I can't see Calendar Invitation Accept, Tentative and Decline buttions also I can't see html links in description e.g. teams meetings which was working properly with old version.

Also our old calendar description not showing after upgradation of new version.

When Month is selected for the Calendar display, and invalid date is highlighted when I click Today. When I restart Thunderbird the correct day is highlighted, but does not update when the date changes at midnight. This happened when I applied the most recent update.

Just a couple of days ago, Google calendar no longer syncs with Thunderbird. I didn't change any settings and it looks like I can't even re-add the Google calendar events it should sync to.

I recently updated my pc to Thunderbird 102.3.3. I cannot get my Google calendar to sync. My calendar is blank. But the available calendars are displayed int calendar panel the left. I've got the Provider for Google Calendar extension installed. It seemed to have started with 102.3.1 update.

Funny thing is on my laptop same version is installed and everything works fine.

I am running thunderbird v 102.3.2 on windows 11 PC. I run the same setup on a windows 11 laptop, this is working perfectly.

My PC is not displaying any calendar content from Google. There is a triangle against the name of the calendar which says that the calendar is "momentarily unavailable." This has been the case for over 24 hours. I have tried uninstalling and reinstalling the google calendar without success.

As well as my laptop, I can access this calendar on my iphone, and my wifes iphone (we use it as a shared calendar). I can also see it online at https://calendar.google.com/calendar/ What do i need to do to get back the calendar function on my PC?

The attached image shows a Month view after selecting "Today" (which is the 10th). There is a random day that has a colored frame around it, and today's day has only the date # colored. Why doesn't the frame move to Today's date?

Incidentally, the Multiweek view seems to work properly, selecting "Today" will move the frame to that day.

When I enter an event on Thunderbird, it is immediately reflected on my online Google Calendar. However, when I enter the event on google calendar website, it does not automatically appear on my Thunderbird Google Calendar. Don't understand this. The only add-on I have on Thunderbird is the 'Provider for Google Calendar' (to allow bidirectional access to google calendar). I don't see any settings to fix this. Help! Note: It updates when I press 'synchronize' on Thunderbird, but I don't want to have to remember to do that. Should be automatic!!

Hi,

I noticed when dismissing any and all calendar event with Thunderbird I'm always presented with a "Item Changed on Server" dialog.

It asks me to "Submit my changes anyway" (even though I've made no changes) or to "Discard my changes and reload"

It doesn't occur on any other app that I use to receive calendar notifications, it should just dismiss when I click dismiss from the initial alert.

Is there something I've missed in the set up or a work around to prevent this dialogue to pop up when I "dismiss" a calendar notification?

Any help would be greatly appreciated.

Version 91 works correctly on other machines. On one machine that is updated to 102.0.1: Create a New Task DOES work for CalDav calendars. Convert mail to task DOES work for local Home calendar. Convert mail to task does NOT work for CalDav calendar. No task gets created. (It does still work in 91.) Move a task from Home to CalDav DOES work if the Home task was created with New Task. Move a task from Home to CalDav does NOT work if the Home task was converted from mail message. CalDav is DAViCal (on Linux, Apache) which is still serving TB ver. 91 machines. All TB 91 and 102 instances are running on Windows 10 21H2 with Firefox 102. Any advice? What more can I tell you?

I have problems reading my Thunderbird (v. 102.4.0) calendar on my iPhone. My email provider offers calendar via CalDAV, and my iPhone connects to it. But it seems to be empty. Does Thunderbird 102.4.0 set up my calendar as CalDAV automatically? Or do I need an add-on? Is there some way to check this?

The today pane is highlighting the last time the app was opened, not today's date. Same problem as https://support.mozilla.org/en-US/questions/1368124 and https://support.mozilla.org/en-US/questions/1210583.

I am on 102.3.0 64-bit with Windows 10. Everything is up to date.

My pc calendar is correct and the time zone is correct. Thunderbird knows the correct date since when I go into settings, the Date Text Format is showing today's date, not the date that is highlighted. I tried renaming xulstore.json and session.json as was suggested on a previous thread.

My problem is that Tb Sync is not syncing Outlook Calendar correctly. When I mark a task as 'completed' on Thunderbird, it remains as 'uncompleted' on Outlook and later reappears as 'uncompleted' on Thunderbird. As a result, I found about 50 tasks going back several weeks showing in red as awaiting completion in Thunderbird . My OS is Ubuntu 22.04 and I am running Thunderbird v 102.4, TbSync v 4.3 and Provider for Exchange ActiveSync v 4.1.5 I am wondering if this has something to do with Microsoft gradually moving tasks away from CALENDAR to TO DO Any suggestions for solving this problem will be much appreciated.

Hi, I want to connect my university timetable to my calendar in thunderbird. The university timetable site (which is running Eveoh MyTimetable) gives me an ics link that does not require any authentication. If I paste this into a web browser I can download an ics file, and if I use this link in the calendar app on my iphone I can subscribe to it, however if I try and subscribe to it in thunderbird, even if I check that it requires no authentication, it asks me for a password, but no password is correct and I cannot subscribe to the calendar.

I'm running 102.3.1 on Windows 10 64-bit.

I use Thunderbird 102.2.2 in Ubuntu 22.04.

Since I updated from Ubuntu 20.04, I have an issue with the calendar. I use Google Calendar for synchronization with other devices. It works well overall, just some events that I have in Google Calendar don't show up in Thunderbird.

I have tried synchronizing manually without success. It happens just with the birthdays, maybe because they are repeating events from year to year, I am not sure.

What can I do to fix this issue?

Any advice would be much appreciated.
