Thunderbird 115.11.0 (64-bit)

Ii recently got a new computer. The old one was getting slow and \i worried about it failing. I am old, and have been slow about getting programs on to the new computer. I got Firefox installed right away, and after a week or two got Thunderbird installed. My problem has been with Thunderbird. On the new computer shortly after I got it installed, all of my incoming mails disappeared. So I went back to using the old computer for email. It was ok. This was several weeks ago. Suddenly this evening all of my emails on the old computer disappeared from the inbox of one of my two email accounts, the one I use most. Now it has totally locked up. Still that way after shutting it down and rebooting. I have looked through the help files and didn't find anything like my problem. I do know that I have never deleted messages. My computers both use imap. I switched from pop a few years ago when Mozilla suggested the change. Going to bed now. will check email in the morning, to see if it will work.

Whenever I try to delete or edit single instances of a recurring event in Thunderbird, it looks like it is gone, but if I close and reopen Thunderbird, it reappears. This happened only recently. I am using Thunderbird 115.11.0 in Linux Ubuntu 24.04. Please advise.

Hello,

I'm kicking the tires on this and the biggest obstacle for me right now is that when I view the calendar in a week view, the day starts at midnight. I would like to hide midnight to 6am.

I followed these steps, that did not work:

1. Navigate to the hamburger menu in the upper right corner. 2. Select settings. 3. In the calendar tab, I changed day starts to 6am, and day ends to 9pm.

There is no way to save this, so I assume it just works. However, when I navigate back to the calendar, nothing has changed. The day still starts at midnight.

Am I possibly looking in the wrong place? Is there a way to customize this as I've described?

Thanks for any help.

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.

My work schedule revolves around the first Thursday of the month. Creating events recurring on the first Thursday or Friday is not a problem of course.

However, I am trying to set up recurring events /relative/ to the first Thursday, e.g. for the Monday of that week.

Can this be done in Thunderbird Calendar? Happy to do some manual editing of calendar files if that would help.

Thank you!

Been using Thunderbird/Lightning for many years. In the latest update (115.10.1 (64 bit)), the EDIT button is not initially visible when I click on an event in my Calendar. In past releases, this edit button has always been visible in the pop-up window when I try to edit info in a New Event task. This happens SOME of the time, but not all. Any idea what changed, and is it possible to check out the code and change it back so when I double-click on an event, I see the edit button. At this time (not a big deal, but slows me down), when I go to edit an event, I have to move to a different monitor, resize the pop-up window so I can see the EDIT button, then finally click on it to edit the Event. In the past, the cursor immediately went to the EDIT button. Any info on changing this back the old way would be appreciated.

How can I get back to being able to search for an old calendar event of up to 2 years ago, now that a recent Thunderbird update removed that ability and replaced it with the 7 search periods option box to the left of the 'contain' search window?

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

I have set up my google calendars in Thunderbird so I can have a shared work calendar.

The calendar has the "prefer client-side email scheduling" option enabled, and the correct email (my work email) is selected, yet invites are still being sent out from my gmail account.

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. ;-)
