Thunderbird Community Forum

When I first opened Thunderbird (just a few weeks ago), I noticed that some Calendar Tasks were already set up by Thunderbird. (My standalone calendar is Efficient Reminder).

But I don't see options for REMINDERS - popups (preferably) and/or sounds. (The purpose of a calendar for me is to be reminded to do things.)

I searched for options in Thunderbird, and I looked on the information here, but can't find anything.

If I can I select a sound and/or popup to REMIND me, where can I find the option to set it?

I used to have a spam folder and now with this new version can not find the spam folder sometimes I might get an email and it may go to to spam so I went to check and sent it to my email need help please

Po ostatniej aktualizacji program działa bardzo wolno. Bardzo długo wczytują się wiadomości wg filtrów (np. nieprzeczytane albo wg słów kluczowych). Bardzo proszę o pomoc

Dzień dobry Usunęłem duplikaty poprzez dodatek i teraz nie mogę odczytać żadnych starych wiadomości proszę o pomoc, co mam zrobić miałem tam bardzo ważne pliki, przywracanie ustawień przed nic nie dało :(

Thunderbird (version 128.0.1 esr) Inbox emails do not contain any data. Last week Thursday, you could look at an email in your Inbox that was received the same day, 3 months ago or 3 years ago and you could see the email, the text, pictures, attachments, etc. Come in to work on Monday and when you click on an email in the Inbox, they are blank. You cannot see any text, pictures or attachments. Note, this is only the Inbox. If you go to the Trash folder, every email will load just fine. I assumed some Microsoft update came through that was causing the problem so I did a restore point on the computer to a date prior to last Thursday. This did not fix the problem. I made a backup copy of the email file by going to "Help, Trouble Shooting Information, clicking on Open Folder next to Profile Folder, backing up "3" directories to the Roaming folder and copying the "Thunderbird" folder to a removable drive. I then installed Thunderbird on a laptop that has never had Thunderbird on it before and properly installed the "Backed up copy" of the profile folder. This resulted in the same issue, some Inbox emails will not open with any text/info, they show up on the list but are empty when you go into the email. Whats confusing is why only some emails wont show any data while others within the Inbox are just fine. Another thought was maybe the file size was too large, but the Inbox file size is 1.9GB, well below the 4.0GB. I did try to run a "folder rebuild" and it deleted a bunch of emails out of the folder, I cannot say for certain if it was only the emails that won't show info or if it encompassed more of them. Good thing I had a backup, so I could restore all the emails it lost. The photo shows an email thread and how it displays the email, no text/images - it has data but will not show anything when you go into the email. This email happens to be from 2022, but I could select an email from yesterday and it would do the same. Note - it is not isolated to an email that has a thread, it can sometimes be a single message. And again, only in the Inbox. All other folders function properly. Any insight would be greatly appreciated.

I have 2 accounts that now quit working. The message said checking email server capabilities. What's wrong? I can get my emails using the same setting on my phone using Auqa Mail

Hi there,

I have Thunderbird on my laptop and map in to that three email accounts. One outlook and two plusnet.

On Wed 31st July this week when I did my daily look EVERYTHING for just one plusnet account has totally deleted. The shell of the email account is still present in the left hand pane, but no content at all. Nothing. All emails and folders and not in trash or anywhere. New emails are still coming in from that point.

On the plusnet online webmail portal they are also gone too.

The other two accounts are totally fine (including the other plusnet account).

I'm totally at a loss as to what happened. It was a totally normal day. I hope you can offer some insight. Thank you for your time. Neil

Today, all my emails in one account are not showing; only the headers. An email that came in at 11:10 is showing but nothing before. It is an IMAP account. When I click on an email, the content is blank. I am using version 128.0.1esr. It was working fine last week and nothing has been updated that I know of. I have several other accounts on Thunderbird, and most of them still work, although I just discovered another that has the same issue. Anything prior to 11am today is not showing.

This BUG has persisted for over two years. Reiterating this question/bug report since it is a constant irritation and for which there was no response previously...

With all the various iterations of the TB Calendar including the latest (currently 115.10.1 - 64bit), it has always been a mystery as to how the organizer email address is selected when creating a new calendar item with invitees. It seems to be somewhat random and it changes for no apparent reason.

In my context I show three calendars, all remote (fruux, CALDAV). All three are configured with usernames and email addresses appropriate for the calendar.

There are two fields in an external calendar properties settings that might apply: Username - the email used to access the external calendar....Not appropriate to use for the 'organizer'. Email - according to the documentation "This is the email address Thunderbird uses to send invitations for events." This would be appropriate as the default organizer but it isn't what is used. Instead the Username email is used. THIS IS A BUG.

One would expect that for a calendar item created, when inviting attendees, the organizer would be the email address configured for the calendar but this is *NOT* the case. Instead, it seems an address is plucked somewhat randomly and applied to the field.

Is this something that can be configured or is it just a BUG? It is painful to have to constantly correct the organizer email and results in confusion with my meeting participants, especially when the invitation arrives from a strange email address.

Note that with upgrades to TB 115 and beyond I completely replaced my TB profile from scratch and the problem has persisted across the profile rebuild. So that does not seem to be a solution to the issue.

"Mail to" extensions and "Send to" do not work with Thunderbird. I'm on Windows 11 and use Chrome, Firefox and the Microsoft Browser. None of them work. Thunderbird works fine on it's own but those options don't work. Thunderbird is the default Mail program.

When I right click on a file and use "Send To", Microsoft Outlook opens.

When I use a Mail To extension or Send to Mail extention (Neither works), my browser tries to go here mailto:?subject=Send%20to%20Mail%20%E2%80%93%20Get%20this%20Extension%20for%20%F0%9F%A6%8A%20Firefox%20(en-US)&body=https%3A%2F%2Faddons.mozilla.org%2Fen-US%2Ffirefox%2Faddon%2Fsend-to-mail%2F%3Futm_source%3Daddons.mozilla.org%26utm_medium%3Dreferral%26utm_content%3Dsearch

and I see a popup that says Send To Mail Opening Mail Handler

Any Help?

I have been using Thunderbird for many years and have previously updated without problem. But upon updating to version 128.0.1esr I suddenly couldn't see my folders or emails (see attached image). However, if I search for an email I will get a list containing the relevant emails, but as soon as I click on an email in the list I go back to the blank screen like at login with no folders or emails.

I have trawled through related fixes and have tried clearing the startup cache, restart and reinstall Thunderbird but nothing helped .

I'm unable to connect Thunderbird to my icloud calendar. I was able to locate the calendar url through my icloud account, but I could not get the set up process to recognize my password. I tried using my icloud password, my email account password, and the app specific password for my email server. Not sure what else to try.

I'm migrating Thunderbird from my old Windows 10 computer to a new Windows 11 computer.

I've installed Thunderbird v115.12.2 and successfully moved all my accounts, emails, calendars, etc., to the new computer.

Several things are NOT working correctly, though:

1 - Settings will not open. Here is the message from the error console:

Error: No such tab mode: preferencesTab

   openTab chrome://messenger/content/tabmail.js:758
   openTab chrome://communicator/content/utilityOverlay.js:257
   openPreferencesTab chrome://communicator/content/utilityOverlay.js:295

   openOptionsDialog chrome://messenger/content/mailCore.js:628
   oncommand chrome://messenger/content/messenger.xhtml:1

2 - Customize menu does not open

3 - The hamburger menu in the upper right corner does not open

4 - The spaces toolbar on the far left is missing

5 - Events and Tasks are missing from the menu

6 - My calendar is nowhere to be found - I can't find a way to access it (on my old computer, I clicked on the calendar icon in the spaces toolbar on the left side of the window)

Thunderbird on my old computer was also running v115.12.2 when I backed up the profile folder to move it.

I tried downgrading to Thunderbird v102. I had all of the same issues listed above PLUS all my accounts and emails disappeared. -- I've brought it back up to v115.12.2.

Could someone please help me get Thunderbird working correctly?

I asked Thunderbird to archive the emails from the first few months of 2024. It created a 2024 folder under the Archives tab. But there are no emails. They have disappeared! Is there any way to recover the deleted emails?

I use the Search Box on the top line of Thunderbird. I have been double-clicking the box to get to a full-page search entry (Duck-Duck-Go).

As of today (6-Aug-24), this no longer works. The only places to search are the address bar, or a very short search bar.

Did this change in the last update? Can it be restored?

Thanks, Lex Rutter Idaho
