Brand new imported domain email account. I accidentally clicked on "Run Spam Controls on Folder" for the inbox for this account, and it marked over 4,000 emails as spam! How do I undo this? Delete the account and re-import it? I didn't set up any filters; I just set up a few tags, marked about 30 emails as spam, and deleted them. That's it.

I am having a major issue with Thunderbird not saving Outgoing emails in Send Folder with IMAP setting.

Having three mailboxes two are set to IMAP and the third set to POP3. The IMAP outgoing mail creates an alert that mail was sent but copy not placed in your Sent folder due to network of file access errors.

Outgoing mail in POP3 save immediately to the Sent folder.

I am using the latest Thunderbird update:

• Server Type: IMAP Mail Server
• Server Name: IMAP.kinect.co.nz
• Connect Security: SSL/TLS
• Authentication Method: Normal Password

Outgoing Server [SMTP] Settings:

• Description - User name
• Server Name: smtp.kinect.co.nz
• Port: 465
• Connection security: SSL/TLS
• Authentication method: No authentication

Note: Authentication was changed form Normal Password in order to gain some traction on the issue during trouble, cause and correction actions.

Addendum: The PC was fitted to Starlink https://en.wikipedia.org/wiki/Starlink in preparation for use as sole source for internet connection. That was abandoned due to email issues.

Recently I have noticed some changes in the way my Thunderbird downloads POP3 messages. Previously, it would be common to ask for new messages once a day and receive upwards of one hundred of them. But in the last month, this number has been limited to about 35 at a time. If I ask immediately again, I get about 35 more, and this pattern continues as long as there are messages in queue waiting to be downloaded. I am not sure if this is due to changes in gmail, where most of my received messages originate, or to changes in Thunderbird itself, or to some sort of third-party hack. Now that I have trained myself to keep on asking until there are no more messages coming down, this change does not cause me much difficulty, although initially it sometimes caused me to overlook messages because I failed to keep asking as long as I should have. Apart from that, it does not seem to be harmful as far as I can tell. I'd just like to know if other people have noticed anything similar, and if anyone knows what is causing it, and whether it has some hidden advantages over the way things used to work.

When I go to delete a message lately, I click the delete button and it checks mail instead of deleting the message. I might be going crazy but 30 years of hitting the same button has messed me up.

I’m running Thunderbird 147.0.1 (64-bit) on both my desktop and laptop, both using Windows 11 Version 25H2 (Build 26200.7705). I’m trying to highlight sent (outgoing) messages where the correspondent and recipient are different (i.e., not sending to myself). When this condition is met, I want the subject line to appear green. My logic is: • Match outgoing mail where the correspondent column contains one of my addresses • Exclude rows where the recipient column also contains one of my addresses • Apply formatting only to the subject column tr:has(

   td.correspondentcol-column[title*="@pm.me"],
   td.correspondentcol-column[title*="@protonmail.com"],
   td.correspondentcol-column[title*="@passinbox.com"]

):not(

   :has(td.recipientcol-column[title*="@pm.me"]),
   :has(td.recipientcol-column[title*="@protonmail.com"]),
   :has(td.recipientcol-column[title*="@passinbox.com"])

) td.subjectcol-column {

 color: var(--tb-green) !important;
 font-weight: 600 !important;
 background-color: #e8f5e9 !important;

} Same Thunderbird version, same Windows build, same CSS file, same mail account structure. Is there something on the desktop system that could prevent this from working? For example: • about:config setting related to CSS • Layout or column differences affecting selectors • Rendering engine differences between installations • UI density / table layout mode differences My expectation is that this logic should behave identically on both systems, so I suspect a configuration or UI state difference. Any guidance would be appreciated.

Bonjour, J'ai Thunderbird depuis très longtemps et j'ai toujours pris l'habitude de stocker tous mes mails dans le répertoire "Dossiers locaux" qui se trouvait toujours sur un HDD différent de celui ou était installé Thunderbird. A chaque nouvelle installation de Thunderbird, je renseignais le chemin ou était stocké "Dossiers Locaux" et hop en 30s, j'avais tous mes messages archivés depuis des années. Je viens de changer de version de Ubuntu (24.04.3 LTS) et la nouveau Thunderbird (140.7.1 esr), donc comme d'habitude je renseigne le chemin de mon répertoire local "Dossiers Locaux" mais rien ne remonte dans Thunderbird ? J'ai essayé (bidouillé) plein de petits trucs sans succès et je ne m'en sort pas ! Pouvez-vous svp me renseigner ?

The ability to select "Done" for New Contacts is totally off-screen on the right when using part-screen (screenshot2 below). When in full screen only a part of the box is available to complete and entry (screenshot1 below).

I've tried adjusting font size and other stuff in Windows 10, but nothing changed the way the Thunderbird looks in this regard.

Is it possible to copy just the Mail folder from a Thunderbird Profile backup in Time Machine on Mac? I have deleted an email account from Thunderbird and I did not tick Delete Data so the emails are still there in my Profile but they no longer show up in the tree in Thunderbird on my Mac ( OS 14.8 Sonoma). I had a lot of subfolders into which I had put incoming and sent emails on particular topics. For example I had a folder called Family, and inside that I had a subfolder called Birthdays as well as many other family related topics. My last Time Machine back up is about a month ago but that would be good enough to restore from. I tried ‘Import’ in Thunderbird but it only imported the main folders and the emails within but not the subfolders. I have another email address besides the deleted one and if I overwrite the whole Profile with the older one from Time Machine it will lose a lot of new stuff accumulated since that backup. Any help most appreciated

Under my main email account in Thunderbird there are two Spam folders. I don't know how a second one was created but I'd like to delete it. When I right-click each Spam folder, only one has a Delete option, but when I select it, the Spam folder doesn't get deleted. How can I delete the extra Spam folder? thanks.

using thinderbird and export we could have calendar.ics and calendar.html now it is impossible to save in html. please help. It was so perfect the calendar saved in html, so we could print all the data perfectly Now the results says that error happen and olny ics type can work

So, from time to time I need to find a sent email, it is not in my sent folder, I check my settings and there it is, I then set it to use my sent folder on the IMAP server, this works for a while, but then seems the next time I want to find something in the sent folder it has reverted back. Any Thoughts?

I have removed an iCloud account from Thunderbird but it keeps asking for the password, I have tried removing all references to the account that I can find including the calendar. Any ideas? Thanks

Messages that I have moved to Archive have totally vanished. A message which I needed to keep I found in 'deleted'. I then moved it to Archive - and it vanished altogether. I do not feel in control of this new Thunderbird! Please, is there any way of getting this message back?

I have been using Tbird for years. I currently have 3 email accounts, an icloud and two gmail. One gmail account is personal, the other is a personal account but used by 3 people for a committee we're on. The first two accounts are ok but the committee account has lost most of its messages at gmail, but they still seem to be on my computer.

Despite having used T'bird for a long time I still need detailed instructions in how to proceed to put the messages back onto the gmail account, hopefully without touching the other two accounts

Sorry - I feel as though I'm monopolising this forum at the moment!

In my Menu bar, I have Delete, but, using this, I can only delete emails from the Unified list, not individual accounts. I CAN delete from individual accounts if I select the email, right click and select delete. Seems odd

No new emails appear to have been downloaded since 12.00 GMT on 27.01.26.

Size of file on disc suggests they are there but not displaying.

Downloads working fine on iPhone and iPad.
