I am new to Thunderbird having just installed version 128.2.1esr. I am trying to build distribution lists, what you refer to as mailing lists. Your support document says to open the Address Book then Select File>New>Mailing List. When I try to do this after selecting File>New Mailing List does not come up as an option. Is there another way to build my lists? Thanks

My inbox in Thunderbird switched to messages alphabetized without me doing anything. I want my messages to come in the order of date & time. How do I switch it back?

As the title says, when I enable the "Digitally sign" option for OpenPGP in a new mail, I get "Sending of the message failed" when trying to send, but if I disable only this option, then the message sends successfully.

That is the case whether I encrypt or not the message.

The versions of Thunderbird I tried where: 115.14.0 and 128.1.1esr.

Please, explain me (with pictures) what should I do, to be able to read my received emails in Tb

Content-Type: image/jpeg; name="IMG_4792.JPG" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="IMG_4792.JPG"

Current version 128.2.1 on Windows 11 and having and having a problem where all current emails with attachments are previewing to an much older email attachment. Tried re installing. This just started recently

Jeg har i adskillige år brugt Mozilla Thunderbird. Har ikke haft problemer før nu. Nu kan jeg pludselig slet ikke åbne den på min pc.( Windows). Fungerer fint på min mobil. (android). Får beskeden: Programmet kunne ikke starte, fordi side om side konfigurationen er forkert. Flere oplysninger i programmets hændelseslogfil eller ved at bruge kommandolinjeværktøjet sxstrace.exe.

Kan ikke se hændelseslogfil når jeg ikke kan åbne den. Kommandopromt siger: sxestrace.exe. ukendt

I have an email contact who uses alias emails to include team members as CC. Such an alias can have the form

  !wawProdAIProjects@domainsample.com

However, the "!" in the local part seems to cause Thunderbird to modify the email address by adding double quotes around the local part:

  "!wawProdAIProjects"@domainsample.com

While both versions seem to be legitimate, my contact's incoming mail server considers the "modified" version with the double quotes as "undeliverable".

So now I am wondering if and how I can stop Thunderbird from adding those double quotes? Any ideas?

Thanks a lot!

Hello,

Even though [replied in another similar thread] that I have the same issue, I'm making another one 'cause it seems pretty dead.

Since ver 128 Nebula, some mails (sorted in a labeled folder) appear totally white / blank and I don't know why. They appear perfectly fine when viewed from my provider's webmail service (Gandi SOGo), but not in Thunderbird. But here's the thing: they appear fine from the sent folder after I replied to them (via the webmail).

I've already tried restarting in safe mode with all modules disabled, to no success.

Hi,

Mozilla Thunderbird graciously provides online calendars for holidays in different countries.

However, since last check (possible since a few days), there seems to be a configuration error:

https://www.thunderbird.net/media/caldata/DutchHolidays.ics redirects to: https://www.thunderbird.net/media/caldata/autogen/DutchHolidays.ics which redirects to: https://www.thunderbird.net/media/caldata/autogen/autogen/autogen/DutchHolidays.ics which redirects to: https://www.thunderbird.net/media/caldata/autogen/autogen/autogen/autogen/DutchHolidays.ics which redirects to: https://www.thunderbird.net/media/caldata/autogen/autogen/autogen/autogen/autogen/DutchHolidays.ics which redirects to: https://www.thunderbird.net/media/caldata/autogen/autogen/autogen/autogen/autogen/autogen/DutchHolidays.ics which redirects to ....

Well, you get the drift :)

Firefox is giving me a warning "The page isn’t redirecting properly. An error occurred during a connection to www.thunderbird.net. "

Please test yourself in Firefox. If the error is still there, please kindly forward it to the thunderbird.net webmaster. If the error is no longer there, it was fixed, and you can close this ticket.

Thanks again for providing this service, I'll look forward to continued use!

i cannot import vcards created in outlook 10 into tb address book. cant import single, group or all in single file. cant import windows or outlook contacts file either. using tb 115.15.

help please.

Good day

I hope you are well. I'm not sure if it's a bug or a problem but here is my problem. My settings are configured such that my sent emails are moved to the folder from where I'm replaying. Now and then the email I just send does not show the content of the email and also does not show anything in the subject or from who it is. The content of the email is random letters and symbols, maybe it shows only the encrypted email for some reason. This problem can not be a device problem because my college ran into the same problem. If I go on my phone (Gmail app) the email in question appears as normal there but not on my Thunderbird app on my laptop. The same problem also appeared from an email received from someone but only happened once or twice.

Please can you assist in solving this problem?

I am unable to attach/send files through other programs or windows - instead of Thunderbird the program will try to use Outlook.

Thunderbird is set as the default map in MAILTO in Windows settings.

This worked fine until recently - I think a windows or Office 365 update may have overriden something, but I cannot find any settings to change to attach and send through Thunderbird.

Any help or advice would be much appreciated

I have a problem with opening messages in the thunderbil program, I keep getting the same error, I downloaded updates, but it didn't help

I have just raise a question here - missing folders after xubuntu upgrade, but I accidentally put "xubuntu 22.04" in the headline instead of 24.4. Can't find my way back to edit the question. Profuse apologies.

I tried changing the authentication method to OAUTH2 for my Outlook live mail account (POP). For that, I had to change the server name to office365.com. After restarting Thunderbird, I was able to download new messages but all the old messages already stored in Thunderbird disappeared, even though Thunderbird still shows the same old Local Directory as being used.

How do I change the authentication to OAUTH2 & get my old messages back?

If I delete & again create the Outlook live account, would it effect my old mails/filters ?

My default browser (Edge) starts when Thunderbird opens requesting a donation. VERY time I start my TBird, the ad pops up again, completely taking over my computer. What needs to be done to prevent Edge opening when TBird opens?

Hi, We do have some problem upon mail synchronization between CPanale mail ( my mail server) with Thunder bird ( on my laptop). We have found that when we access my mail server ( CPanal ) directly and   delete some mail, that mail ( In my Thunder Bird mail box - upon my Laptop) will be automatically removed from my Thunder Bird mail on my Laptop. I want to delete file from mail server without any automatically synchronize delete file in my Thunder bird. How can i set up Thunder bird?

Previously all of the email accounts created in thunderbird worked flawlessly, one day when checking email automatically a seperate window opened displaying the error "Access Denied", I searched the net for a solution and could not find one, it is very possible that one of the most recent linux updates may have changed something as I recall a larger than normal update just before this occurred a few days ago.

Thank you.

Access Denied You don't have permission to access "http://login.xfinity.com/login" on this server.

For about a month now Thunderbird has been taking sent emails and doing one of several things. 1. Replacing the text with lines and lines of numbers and letters, 2. Removing the "From" and "Subject" lines and the message, leaving the message blank, BUT adding an attachment that has nothing to do with the recipient; 3. Sending some sent messages to trash after I have tagged them. I use emails like a paper trail, to check, to see if there are any emails I am still waiting to hear an answer back on, etc. Thunderbird has been my favorite email client since I was first told about it. Please help. Thank you, Lisa Icenogle
