Running Windows 11 and TB 150.0.2. Can't recall exactly what I did, but after clicking on an email all unread emails are no longer in boldface. Any way to restore them? (New emails that come in are in boldface.) Thank you, Joel Hornstein jobby@att.net

I open Thunderbird and see the list of received emails as usual and I have a "Viewing Pane" on the right. In the viweing pane I can see a portion of the email. However, there is a line going through the top portion of the viewing pane email and I cannot see what is under the line. I then fully open the email and the line is still there.

I have tried everything I can think of to fix this to no avail. I have even shut down Viewing Pane in settings and even then when I open an email it is still there.

I am trying to get Thunderbird to function in similar manner of Outlook Classic but the simplest of settings such as viewing pane just won't work. Thunderbird is up to date and Cache cleared. I have attached two photos to show what I am seeing.

I keep my mail (both sent and received) in local mail folders. My server is gmail, and sent mail is put in gmail's sent folder by default. Every few months, I copy those messages to a local folder, and after I back them up, I delete the server copy.

What to my dismay, I discovered today that only the message headers, and not the messages were present in the local folder, though they had been when downloaded. Looking at the file sizes, I found the sent file to be 0 Kb, and sent.msf 255 Kb, when sent should have been around 60 Kb long.

I have been able to restore the messages from backup (whew!), but I have no idea how then sent file was wiped out. I know I did not do it.

Has anyone else had this happen? Is there a preventive measure I should take?

I have just transferred my website to crazy domains and in order to set up email they need DNS records for thunderbird. I dont know how to access this. Could you please provide these for me.

Hi

I'm using Thunderbird 140.5 on a desktop Mac running Sequoia 15.7.2

In Local Folders, my subfolders have subfolders. In both levels of subfolders, Thunderbird has spontaneously started disordering both newly created subfolders, and folders which I move from one subfolder to another using right click 'Move To'

Up until ten days ago, all folders whether new or moved, were listed alphabetically. Now, day by day, the disordering is getting worse and as someone with ongoing conversations with hundreds of clients, it is becoming impossible to work when I have to give so much time to slowly scanning through every folder looking for the relevant subfolder.

I don't know why I can't update this version, but I tried installing the newest version available (145) and used the 'reset folder option' which did not work either.

Also, setting up a whole new account instead of upgrading my existing account is a colossal faff and I'd rather not have to!

Aside from manually reordering (also a colossal faff), can anyone suggest something I might be missing in stopping this happening?

Thunderbird says I'm on an esr channel, if that helps

Thanks

For the last 2 months I have been working to configure Thunderbird to fully replace my Gmail UI usage after their recent change to workspace options and using data to train gemini. When you deactivate those gmail features the first thing you lose are tabs for your Inbox, your Updates and your Promotions.

So far I have used tags, ThunderAI, Ollama and a locally hosted LLM to replicate the sorting of my inbox, but now I would like to be able to configure the Thunderbird UI to allow separate tabs in the menu bar for different folders, in this case Inbox, Updates and Promotions. With Inbox still being the gmail hosted main inbox and Updates and Promotions now being local folders stored in my local thunderbird installation.

Can the Thunderbird UI be configured to display folders as tabs as a default setting? I tried the "folder selection" button under customize on the toolbar but that just gives me a drop down, which is not what I want.

Mail filters for custom headers like List-Unsubscribe, Authentication-Results or Received-SPF copying messages from IMAP accounts to Local Folders do not work on the Yahoo! IMAP account. For example:

filter1.jpg: name="_Inbox2: List-Unsubscribe <https" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox/_Inbox2" action="Stop execution" condition="OR (\"list-unsubscribe\",contains,<https)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

filter2.jpg: name="Spam: Authentication-Results dkim=unknown | Received-SPF fail | X-Antivirus-Status Infected" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Junk" action="Stop execution" condition="OR (\"authentication-results\",contains,dkim=unknown) OR (\"authentication-results\",contains,dkim=perm_fail) OR (\"authentication-results\",contains,dkim=none) OR (\"received-spf\",begins with,fail) OR (\"received-spf\",begins with,softfail) OR (\"received-spf\",begins with,none) OR (\"x-antivirus-status\",is,Infected)" (should copy messages from IMAP folders to _Inbox 2 on Local Folders)

But filter3.jpg for Subject works well: name="Inbox" enabled="yes" type="17" action="Copy to folder" actionValue="mailbox://nobody@Local%20Folders/Inbox" condition="OR (subject,doesn't contain,t[k\6iq69pd+}'cr)" (copies all remaining messages from IMAP folders to Inbox on Local Folders)

(the snippets above are fragments of the msgFilterRules.dat file)

Filters1 and 2 work well on other IMAP accouns, like for example wp.pl. So this is about Yahoo or something is corrupted. My question is, what wrong is here ? And by the way - how to create filter copying all messages from IMAP to Local Folders ? Is better way then filter3 looking for random string in the subject or somewhere else ? Thank you.

Hi, I use thunderbird as both POP and IMAP through gmail. I keep all my emails on my POP thunderbird desktop client. I use IMAP on my thunderbird laptop client, iPhone, iPad via Apple mail when remote, then download the emails to my desktop.

What I want to do is read emails and set them to archive on my IMA laptop, iPhone, iPad. I know Gmail tags the archived emails. How do I stop thunderbird from downloading the archived emails to my POP thunderbird desktop client?

Thanks! Art

I successfully set up three of my Google Gmail addresses on Thunderbird. I tried to set up my fourth and primary Email address, which is on a Spectrum server, using the absolutely correct address, user name, and PW. Thunderbird will not accept it, saying there is an "authentication error", but not identifying what it is. How is it possible to fix an error, if no precise error is specified? Thanks for any help anybody can offer.

Had a double disaster, both OS partially upgraded at same time due to space issues and had to wipe and install.

Ended up with a TB install in Ubuntu where 2025 emails are missing. (see image #1) Found out that my backup should have most of them. (see image #2)

How do I safely identify the 2025 mail content in my backup folder, and how do I safely copy them over to the existing set up?

I see that the 933 profile exists in both so most likely it should be one of the lower number profiles in backup I need.

Attached are images of folder content.

Many thanks in advance!

I am trying to set up a visualization of the columns of the main interface. Here's what I do:

1. Click on the list icon in the top right corner.
2. Uncheck the columns I want to hide. Specifically, From (CB), Recipient (CB), and Correspondents (CB).
3. Apply the selection to all folders: click on the icon in the top right corner, apply columns to.. > folders and its children... > select account > Confirm

These actions produce immediate results. However, the next day or a few days later, when I reopen the program, the column display changes. Sometimes in the main folder (inbox), sometimes in the subfolders.

Is this a known bug? Is there anything I can do to keep the desired column configuration stable?

good day, i'm trying to add a new GMX email account to thunderbird, but i keep getting an error telling me that the user name and or password are incorrect, but they are not. i already have two (2 ) other GMX email accounts on thunderbird and they are working just fine. i had a similar issue last week with my Hotmail/Outlook account telling me it couldn't connect for the same reason, but that seemed to work itself out and that one is working fine. i've been using thunderbird for quite a while now and never had any issues integrating GMX email accounts. thank you for your time...Mike S

Ich erhalte die Meldung "Nachrichten konnten nicht in die Mailbox-Datei geschrieben werden. Stellen Sie sicher, dass das Dateisystem Ihnen Schreibrechte einräumt und genügend Speicherplatz zur Verfügung steht, um die Mailbox zu kopieren." Speicherplatz ist genügend vorhanden. Bis jetzt konnte ich meine Emails problemlos abholen. Bin erreichbar über Telefon [edited] oder Handy [edited phone#'s from community support forum]

I can see where the Local Files are saved under .sdb folders and msf files. I can save these to a USB stick as a backup BUT can I perhaps open on another device also running Thunderbird. Is this possible and how? I can't see an 'open file' in Thunderbird.
