When I receive emails with calendar invitations, I can't put the event into my calendar because Thunderbird says that I have "no writable calendar". In the Properties for my Calendar, when I try to associate the Calendar with an email account, I see two, sometimes in the past three, identical email addresses listed, and that's the email address that I need to associate with the Calendar. Sometimes, I just keep trying one after the other until my Calendar becomes writable and I can save the emailed invitation. However, most of the time, no matter what email address (in the Properties list) that I choose, I still get the error that my Calendar is not writable.

I use Thunderbird with Exquilla for Microsoft Exchange. That works fine. Earlier, I had tried Thunderbird with Owl for Microsoft Exchange, which also seemed to work but my office suggested continuing with Exquilla.

Thank you for any assistance with this showstopper problem. Best regards, Damon

In 2020 I had asked how it's not possible ( and after what, 10yrs of Lightening being in production ) that in 2020 that when a person ( we will call him Bob ) send another person ( we will call her Sally ) an email ( and there are 2 other people on that same email ) that when Sally wants to QUICKLY and EASILY setup a meeting that people from the email from Bob are not just added to that new meeting and you are done?

This should be INCREDIBLY incredibly easy to do: right click --> Convert To..... ----> Event and then when the dialog box pops up, Bob, Sally, and the 2 other people are added to that meeting. Yet, No. Three years later? How can this be ?

In the original post https://support.mozilla.org/en-US/questions/1295910 and as commented on by @sfhowes it was suggested to ask on the chat groups. Yep. Did that. Nothing. Again, How can this be?

So, Let's add up the time it takes to do this, the number of clicks, etc,. and it's more than 5 mins just to go back and forth to the original email, copy and past peoples names and put them into the "attendees" dialog box. If I have to do 10 of these a day - and I often do, that's 1hr a day of meeting setup that I could do in literally 1 min if the above functionality worked and which it does on just about EVERY other email platform out there. Add this up, 1hr a day, 20 work days a month that's 20hrs a month * 12 = 240 hrs or TWENTY FOUR DAYS of our lives wasted every month making calendar invites where if right right click --> Convert To..... ----> Event and peoples names and email addresses were already added, this would not be happening.

Is there someone at Modzilla / Thunderbird / Lightening that we can pay to put this functionality which was clearly there in the past back, so we can ALL have 23 days of our life back every year? :))))))))))))))

It's 2023. This functionality is clearly needed to be enabled again.

My TB is up to date (102.7.2) and in the last week or so my Yahoo calendar is not syncing and when I hover over the warning symbol it says '...temporarily unavailable'. My Outlook calendar is syncing and showing. Any ideas how I can fix it ?

Thanks - Ed

Some event reminder popups aren't being displayed. There's no apparent reason as to which reminder popups will work properly, although the problem seems to occur mostly with event reminders dated in the future or with reminders that use a custom reminder date/time (e.g. 16 days prior to the event). If I can't depend on the reminder popups then the calendar feature is useless to me.

Also, another slight annoyance is that the events cannot be sort by date, it refuses to sort them in chronological order. FYI...sort by name works.

Hi Team,

Can someone tell me a way for me to link my calendar from my home computer to my laptop via Thunderbird?

Reference: I use my home computer more but when I am traveling I would like to see my calender schedule mirror my home computer.

Kind regards,

Shamus

All my calendar events disappeared! I checked the About Thunderbird, and it wasn't on the latest, so it must not have been an auto-upgrade issue. I clicked to upgrade to the latest, 102.8.0, but my calendar events are still all gone. What can I do?

I have always exported my calendar events in the CSV format to upload them to Google Calendar. That's gone. The Ical exported file is incompatible with Google Calendar. When attempting to import I just get a message reading:

"Imported 0 out of 0 events. Unable to process your iCal/CSV file."

I'm using version 102.3.0.

Any help is appreciated. Restoring the CSV export function would be even more appreciated.

I see that I can save an ics file from an email or website and import it from within thunderbird. I want thunderbird to be my default calendar app, so I can just click on / open an ICS file and it does so in Thunderbird, NOT Outlook. I don't even see a way to uninstall outlook without having to uninstall office altogether (not a viable solution).

TB 102.6.1 / Provider for Google 102.

I have a number of calendars with my google account. Syncing works fine except for one of the. Events I enter in the Google app don't show up in TB, but the reverse works (TB --> G).

Any suggestions.

I know I can always create another Calendar, copy the old to the new, ..., but I hope there is a more elegant solution.

Thunderbird version 102.7.1 The "today pane" in lower right covers part of the scroll bar. So I would like to hide it. The one other answer on a related question does not work; the X button just minimizes the "today pane", it does not hide it. The view->today pane->show none button is grey'd out, so that path does not work.

I'd like to make a plugin that adds an icon to the days of the calendar indicating the phase the Moon will have on that day.

There seems to be little up to date documentation on making extensions for Thunderbird's built in browser and there doesn't seem to be any information on making plugins that change the calendar. Is it even possible to make such a plugin? If so, what is a good starting point for learning how to do so?

Cheers.

In older versions of Thunderbird, an ICalendar feed I use displayed events as expected. Newer versions do not. The feed displays as expected in other applications such as evolution. I ran the feed through an ICalendar validator and it came up clean.

I also brought up the developer tools panel, but saw no errors on the console while accessing the feed. Help is appreciated.

The attached image shows the evolution calendar displaying the events in green.

Thank you,

I had a big event related to security on my ISP last year and I moved my calendar and contacts to an internal cardav and caldav server in my hosted Synology NAS. I was able to setup Thunderbird well and I did assigned a calendar identity to the calendar with local management of the invitations. In the configuration, it correctly shows, as in the article (https://support.mozilla.org/en-US/kb/enable-email-invitations-caldav-servers-configured) that I prefer Client side email scheduling and I have assigned one of my email accounts. The problem I have is that when I create a calendar entry and state that I want to invite people, by default it states that the organizer is otto.acuna@local.host, not the email identity I assigned and that it shows in properties

Any ideas if this is something I need to edit somewhere internal? Thank you in advance for your help Otto

Im using thunderbird with a nextcloud calendar Nextcloud v25.0.3 Thunderbird v91.13.1 DAVx (to sync on Android)

All my calendars sync across the devices and Ive added my caldav calendars to my mobile devices. When I try send an invite, from Thunderbird, to someone else in our organisation to accept on their mobile, the invitation sends an email with 2 attachments 'invite.vcs' or invite.ics' So there is no option to accept or decline, if I open the attachment the only option I have is to save to calendar, but that will also not send an accept or decline. If I send the email to another address, for example a gmail address, the inivite sends exactly how you would expect and has the accept or decline buttons.

If I send an invite from my mobile device to thunderbird, the invitation sends as expect. But once I try accept or decline in thunderbird, no response seems to be sent back to my mobile device or atleast nothing i can see If I send from mobile device to mobile device, there is an option to accept, which opens a browser window, but atleast the option is there. It also has an attachment, this is 'event.ics'

So I think the issue is somewhere with thunderbird, but Im not sure. Would really appreciate any help

When new item is added to my Google calendar via Thunderbird that I share with my wife it is updated on my Thunderbird calendar it doesn't update my wife's Thunderbird calendar even using the synchronize command.

We have close Thunderbird and reopen it to get it to upload to her calendar.

Is this known bug?

1. Today on opening Thunderbird I get a page with all the new features - can't find that after closing - can you give me a link?

2. BIG PROBLEMS though now with my calendar - all my repeating events have disappeared & it won't let me add new ones, only single events. I need this to work like it used to asap.

3. I want the daily events pane to be back on the right side of my screen - but can't find a way to make that happen - can that be done?

4. When the reminder pop up appears, if I click dismiss the now empty pop up screens stays open - how do I get it to auto close after I select to dismiss or remind me later like it used to?

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 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.
