First, there used to be a columnar format that included a heading. I could sort entries by double clicking the column heading. This was handy for selecting email by date and deleting or moving them. That seems to have disappeared in Versiona 128.9 Oesr. Is there a way to recover that view?

The reason I discovered this is that I'm receiving a message on virtually every attempted Thunderbird operation saying that there is not enough disk space to complete the operation. I cannot tell if this is a Thunderbird message or a Microsoft (Windows 11) message. I've attached a screenshot. I've checked and there should be plenty of disk space; but, of course, there is a lot of spam mail in my T-Bird that I could easily delete. I've tried setting up Message Filters to delete unwanted email but that, too, produces the error message.

Can anyone tell me how to a) get my column headings back in T-bird, and b) fix whatever is causing the message?

after migrating to new windows 11 pc's how do I set Thunderbird so it will show that you have opened an email off the server at your terminal but others viewing same email account will see it as unopened until they open the email at their terminal, I have settings to not "automatically show as read" on all 3 terminals but now all incoming emails stay black highlighted as "unread" for all users sharing this account even after all 3 user terminals have actually opened said email using POP server

I think it started to happen with Version 128.9.0esr | Released April 1, 2025. It is very simple to reproduce: 1. Start TB. 2. TB downloads new messages and continues to do it every 1 minute according to the setting. 3. In 10 to 20 minutes, it hangs. I have to force it to close and then restart it to check my email.

I believe it started to happen yesterday.

Is anyone else experiencing this?

Whenever I select a message, Thunderbird automatically opens the message in a new tab. It hasn't always done this, and I don't want it to. It just started doing it one day and won't stop.

This is particularly painful when I select 10 messages to delete and instead I get 10 open windows! Please help me stop the madness.

I'm recovering from a computer disaster and thus have a fresh install of Thunderbird without any of my old emails or message filters. Previously, when creating filter rules for junk emails, I used the option to create an action rule to delete the message from the server. The sequence was "Set Junk Status to: Junk" > "Delete Message From Server" > "Delete Message." This way I didn't have to manage the emails on the server. I want to continue this, but I don't find the Delete Message from Server option any longer. After reading other articles saying IMAP was a prerequisite for this action rule, I tried to set up a second account using IMAP but TBird told me the existing account was already set to IMAP for incoming mail. Confusing. But the bottom line is I need to know how to access this action rule going forward.

Hi,

I need help on topic "Outlook, PST, EML and local folders".

I have .. - Win 10, 64 bit - Outlook 2010 - current thunderbird, first time installed 10 days ago (newbie!) - a huge, locally stored PST file with a lot of folders, like "in_2014 / In_2015 / .. / Out_2014 / Out_2015"

I want .. - to have access to the mails in the PST with Thunderbird.

I did .. - read some information and found that there is no direct access - install ImportExportTools NG - tried to import "Via Outlook", but failed: "No profile found". I think Outlook 2010 is too old - install "Outlook Viewer" from CoolUtils. Opened the PST, exported a lot of EML-files, one for every single mail. - defined a "Local folder", called "in_2014" - copied the EMLs to this folder. They appear in the folder-tree of Thunderbird, but not as single "mails". I have to open (doubleclick) every EML to see the mail. - tried to "Import" the data (one by one / many together / from folder) to the local folder, but got a long error message with a lot a strange error-codes - tried to export data from PST to one single EML with many mails in it. Failed, the software does not offer this feature. - tried to "Import" the EML to a folder of a mail account. This was successful, but only the first step. - tried to move / copy the currently imported mails from mail-account to my local folder: failed again without reaction and without message.

What can I do now? How to get mails from a PST to a locally stored, Thunderbird readable structure?

Thanks in advance for help.

I am finally making the move to ditch Microsoft Outlook for good and use Thunderbird as my daily driver for all my email needs. One of the things I did appreciate about MS Outlook is that it has a setting where if you've opened up an email and either delete it or move it to a sub-folder, you can set it so that the program will open either the next or the previous email in your list automatically so that you don't have to go back to the main view every time.

I've tried searching the support forums to see if such a feature exists in Thunderbird but I have not yet been lucky in finding any recent information. Does such a feature exist or has someone written an extension that can do this?

Hi,

When saving an edited message in Drafts, the original message gets overwritten/replaced by the new one. That's fine.

But when saving an edited message in Drafts subfolder (Drafts/ProjectX), a new message is created directly in Drafts and the original message stays in the subfolder. Please is there a way for saving messages in Drafts subfolders to behave the same way as saving messages in the Drafs folder, i.e. overwriting/replacing the original message wherever it is located.

Thanks a lot,

Pavel.

Had issues with Comcast emails. They were set up with POP settings. Was on the phone with Comcast and uninstalled 3 email addresses and reinstalled using IMAP settings. I did not delete the message data leaving that box unchecked. After about 1.5 hours on the phone with Comcast was able to get the reinstalled Comcast email addresses to pull all of the emails off Comcast website. But there are emails that are missing from each of the inbox and sent folders for each of the 3 Comcast email addresses.

I do an incremental weekly backup using Acronis True Image 2020 Home Edition. I see the folders in the path but since they were saved last Saturday under POP settings, the backups I will need to try to recover are in 3 of the Comcast folders in the "MAIL" folder and not "IMAPMAIL" folder which listed 6 folders from imap.comcast1.net through imapcomcast6.net.

What do I need to copy from the correct Comcast folder called "Profile" where the izpoojy7.default is? Within this izpoojy7.default is the folder mail.comcast-1.net which has 1 of the 3 Comcast email addresses I need to recover the inboxes and sent folder emails. Please see the attached photo of the contents of this mail.comcast-1.net folder.

Do I just copy the Inbox.mozmsgs as well as the Sent.mozmsgs files? Or do I also need to recover more of the files within the respective mail.comcast-1.net folder? Thank you for any assistance you can offer on this matter.

Hello,

Recently I have started to have emails fail to deliver to a certain domain and the message that comes back is

550 DKIM Sender Invalid - envelope rejected.

I am using Thunderbird v128.8.1 esr (64-bit). Extensions installed are: 1. Attachment Saver (Deimios, v.0.2.2) 2. FileLink provider for Send (Teal Dulcet v2.1.1) 3. Remove Duplicate Messages (Eyal Rozenberg v0.6.1)

I have been in communication with this client for several years and not had this problem before. When I send email to the same recipients using WebMail there is no problem, it is only when I send from Thunderbird.

I am not using any encryption type of setup.

Has anyone come across this before? Does anyone know of a solution?

Thanks, Franc.

Dear Sir or Madam

I tried to send some emails to some friends. All mesage aare with identically content, Subject and data. But that was not possible. See please for example attached screenshot.

After that, i used directly Email server (Hostinger), with CAPTCHA and sent all emails for these some friends.

How you can see "Subject" is: VOTING LINK - RHEIN Circuit 2025

We do not send "Spam". That is only 7 or 8 emails.

My Question: Why Thunderbird do not allow that I send these email. And show this error message? All another Email send without any problem. As allways.

Thank you in advance for your Support.

Regards, Jacques

Bonjour, Je viens de télécharger Thunderbird pour Mac. J'aimerais pouvoir importer un fichier mbox.

Pour cela, je souhaite ajouter l'extension "ImportExportTools NG", mais celui-ci ne peut pas être installé car "il n'est pas compatible avec Thunderbird 137.0." Et il n'y a pas d'extension plus actuelle.

Comment faire?

Merci de votre aide.

Please help, I had a hack on my account henryk@cichon-stolarka.pl. I currently have access to the account and everything works but I can't send an email. Please unlock the account.

Best regards Henryk Cichoń

Hi, I would like my incoming mail list to show each individual email as a separate item and more importantly with it's own arrival date, not as they currently are; all under the first email with that subject heading.
