I have a Google Calendar, in which I manage My Tasks. I can't see my existing tasks in Thunderbird, and I can't add new tasks to the Google Calendar. New Task in Thunderbird is greyed out and the field next to it has the writing: "Please select a calendar that supports tasks".

I have seen that many had the same issue and understood that it is linked to how My Tasks in Google Calendar itself works. Is there really no workaround whatsoever?

If not, how can I manage tasks and share them with someone else (who uses Google Calendar or Apple Calendar, but does not use Thunderbird)?

Thanks in advance for your replies!

I have Thunderbird version 115.5.1 installed on my Windows 11 laptop. I have logged into my gmail account and subscribed to google calendar. I have turned the off default reminders for events and don't have any extensions installed, but when I create a new event and select "No Reminder," Thunderbird automatically sets a 30-minute reminder. I can modify the reminder by editing the event after saving, but I can't directly create a new event with no reminder.

Hi,

Scenario: I have a custom domain with an email address, and have used mailbox.org and currently icloud to host my email. In both cases, the email address associated with my custom domain is the only one I use for everything, such as email, calendar, contacts, etc (x@er.com). Also in both cases, there is also a login email address to the email hosting service (i.e. x@mailbox.com and x@icloud.com respectively).

Issue: My calendar invites erroneously send from my icloud email address, rather than my custom domain email address. This appears to be by defaul and unchangeable. See 1/2 screenshot.

Settings: I'm on W11 Pro, using TB 115.10.1 (64-bit). For calendar settings, see 2/2 screenshot.

Background: With both providers, my calendar invites initially were being sent from the correct email address (x@er.com), but inexplicably switched to the being sent from login email address of the email hosting service after some time (about a year with mailbox.org, and a couple of months after migrating to icloud.com). This messes up my calendars, and I need to resolve it. Hopefully it's just something dumb that I'm doing.

What I've tried: On mailbox.org: When the issue first occured I put up with it for a few weeks then assumed it was probably mailbox.org and migrated to icloud. This appeared to resolve the problem at the time. On icloud, my calendar sync was setup in TB using add-ons, which worked for a couple of months and then the issue recurred. I've tried: 1. In apple account settings: I tried changing my apple-id to be my custom domain email address, rather than my icloud email address (didn't fix it). 2. I then unsubscribed from all of my network calendars in TB, removing the addons and restarting TB, as per https://support.mozilla.org/en-US/questions/1406255#answer-1568028 - I had to add a blank local calendar first before I was able to remove all of the network calendars. 3. I then added my calendars back into TB by using the direct URL locations, as per https://support.mozilla.org/en-US/questions/1406112 - when adding the calendars back, I tried using the login as both my custom domain email address, and also my icloud email address (didn't fix it).

Any help would be much appreciated.

Thank you.

Hello, in TB there is the option of displaying certain appointments or all appointments, e.g. in the next seven days (above the calendar). This also works perfectly on my Windows computer, but unfortunately not on my Linux computer (Ubuntu 22.04.4 LTS, TB 115.10.1 (64-bit)). In TB on Linux, no appointment is displayed as a list at all. What could be the reason for this? Thank you! Niels

One of my calendars is not syncing. The same account (O365) also is not syncing the sub-folders.

Not sure what setting may be off.

I added some events from Outlook for Android on my phone sync'd to the same account. But they don't seem to appear, although they are on Outlook Web Access on the browser on my Windows machine.

I'm setting up TB for the first time with multiple email and calendar accounts. Some are gmail / google, and others o365.

The primary TB account's calendar doesn't seem to be syncing fully. It's an o365. account. But the email is working.

I added an event on my Outlook for Android on my phone. Its appearing in OWA, and in New Outlook on my computer (so it did sync from mobile Android device to server, and from server to my New Outlook on the Windows desktop). But its not appearing in TB.

Not sure what to check or what the issue might be.

Also, I'd love to replace Outlook Android on my mobile with what I think is K-9. But can't get the same account referenced here to connect to the outbound server.

Welcome any help, and appreciate you all doing this collaborative work.

Hi Everyone!

I am currently on Thunderbird 115.10.1 (64-bit) and for a few days now, I can't open the calendar tab. The "Today Pane" is working and showing events though.

When going to "View" the items "Calendar" and "Tasks" are greyed out though.

Any idea on how to get the calendar back? The company will move us all to Exchange and Outlook soon, so I thought I might "survive", but it is pretty impractical have to open my calendars separately in the browser. You only notice how often you use something, when you don't have it. ;-)

I am in the middle of creating a new event. If I click on the "Invite Attendees" button an "Invite Attendees" dialog appears with an email address already loaded in the first line. In my instance, this email address isn't mine! It is an alias on our corporate Zimbra email system that hasn't been used for 15 years, but is nowhere in my Thunderbird v102.15.1 client. It also isn't in any of my Thunderbird accounts. Where can I define this?

Profiles was bad enough, as Thunderbird can never open the zip file (the wording of the alternative method is gobbledegook, and there are no recognisable files if you attempt to decipher it). At least you can set all your email addresses up manually - you can't physically re-types five years of calendar entries. The infuriating this is that when you start the import, the calendar entries appear before your eyes for up to five seconds and then the program crashes ... again and again and again. I must have been trying this on and off for years now and still nobody has fixed it.

Computer crashed. After restoring, Google calendar is not syncing. No error message that I can see. I unsubscribed and resubscribed to no avail. I have no clue what to look for and searching here is not helping as all the references to this are years old. Can someone help me figure out why this is happening?

Is there any way to select other than the "home" calendar as standard? Have tried to change order in the calendar setting, but when I accept a meeting invitation it always place the meeting in the home calendar. I would like to select the syncronized Google calendar.

The syncronization with Google calender works perfect when manual enter something.

Best regards /Mike

Hi folks, I am wondering if there is a way to change the behavior of the pop-up reminder window in Calendar. When I have missed reminders (e.g. a task set for today at 8am and it is now 9am), the task is visible in the reminder window that pops up every time a reminder is active. This is fine. But if there is a past reminder (not resolved), every time I add a new task (or edit a past task) to the calendar, the pop-up reminder window opens and comes to the front. Let me describe the example: I missed (knowingly) a reminder at 8AM. Now, at 9 AM I need to add 3 new tasks to the Calendar. After setting (or copying, editing) each new task, the pop-up reminder window is focused on the front. Can I change this behavior so that the reminder window only pop up when the reminder is due and not in the case a new task is set up or old one edited?

I would like to have a unified calendar that when an event is added to my gmail or outlook calendar it gets copied to the unified calendar.

Is that possible?

can i shut it off this way I do not gnat encryption and i am using Norton a d i also use ccleaner and glary does this have anything to do with it

Thunderbird's Calendar displays time for events from Google's calendar (probably other network calendars too) incorrectly. For example, i create an event with "New Event", select "Calendar: <my gmail account>" and set "Start: 15:00", "End: 16:00", then "Save and Close". Thunderbird Calendar displays it as from 16:00 to 17:00. "Use system timezone" is selected in Calendar settings. When i open "Edit" dialog for the event, time in "Start:" and "End:" fields is also incorrect (16:00 and 17:00 respectively). However, when i go to "Options" and click "Show Timezones" it becomes correct (15:00 and 16:00). Disabling "Show Timezones" leads back to incorrect time. Web page and other applications display time for the same event correctly (as i set it during creation). The same error for events created not by Thunderbird but on web page or other applications. Thunderbird 115.9.0.

New version of TB and again event colors are gone.

I used the patch Todd gave me in the previous topic with the same name, archived. It worked after again half an hour of useless work.

When will TB include this in standard coding?

Something changed at some point in time with the calendar file. When I started using Thunderbird I was able to set up entries in the calendar file and give them names and an associated colour. I can't seem to do that any longer. Eg. I set up entries for Birthdays which showed on the calendar as purple and Anniversaries where green. I can't do that anymore. Was that ability removed at some time?

Another situation I came across was importing .ics files. The method changed and now you have to open a file. What it does is ask where you want to put the contents, ie as an Event or a Task. I tell it where I want it put . But when I check the entry it shows as the .ics file and not as an Event or Task. Then I have a terrible time trying to remove it. Nothing happens when I tell the program that the Event/Task is completed. HELP!
