Am getting this message along with a recurring download of a specific email (keeps coming back even after deletion) that does not allow any other new messages to be downloaded. I do see new emails on my phone but will not read into Thunderbird??

Error: "Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox."

Tried: Troubleshooting, closing Thunberbird and reopening, rebooting windows system, compacting, etc. to no avail....

Hi all. Is it possible to send 400 mails and attach different .pdf files.? I have the e-mail list in a cvs file, and 400 *.pdf files placed in a folder. I know that it might be done i Google mass mail, but I would prefer to use Thunderbird the same way. Does anyone know if this is possible?

I am writing an email and selecting addresses from address book. Several select ok but one is selected but once on the To: line there is a dot next to address and when hover over get msg: "Joe Doe <joe.doe@hotmail.com> is not in your Address Book.

We have 3 different laptops on the work thunderbird email and the one that has been on it the longest now says that it cannot verify the identity of our work server.

When we go to verify the certificate, it says that the certificate name does not match the report. How does one go about fixing this?

Would it make a difference that the laptop has been out of the country for a few weeks as well?

How do I restore emails from an email backup (that is NOT a backed-up profile zip file) that has been saved using ImportExportToolsNG? I used ImportExportTools NG to create an email backup. The backup is in the forms of files in a set of folders (calendar-data, crashes, datareporting, extensions etc.). It is not in the form of a zip file.

Hi,

I'm experiencing issues with threaded view in Thunderbird (version 139.0.2 on Windows). Some threads do not display all messages -only a few emails are shown (e.g. 2 out of 8), and others are missing from the thread view even though they are present on the server. Rightclicking a message and selecting "Open message in new tab" sometimes works (but still doesn't show all messages), and sometimes it doesn't open a new tab at all. the missing messages do exist on the server, and I can find them using Ctrl + Shift + F , but they do not show up in the thread, nor do they appear via Global Search, even though the global index has finished building.

I have tried the following: -Right-click folder > Properties > Repair folder -Deleted and rebuilt global-messages-db.sqlite (global search database) -Reduced IMAP mailbox size from 140GB to 110GB -Waited for reindexing to complete

But the problem persists. It seems that Thunderbird either doesn’t associate all related messages with the same thread, or skips them entirely in display and search.

What can i do to fix it? Thanks in advance

Recently, after upgrading to 140, I noticed that text replacement on MacOS (Sequoia, here) seems to be functioning differently within Thunderbird; differently than in other apps I use.

What's happening is when I type a known shortcut, say "pr", the modal for the replacement pops up; if I continue typing my preferred word, the text replacement is simply inserted. I now otherwise have to press ESC to stop this. Before, I could ignore the pop-up modal and just keep typing -- that is what we expect in other apps, and this seems to be the case in Firefox (which I'm using now, and it works fine). This suggests there may be some change or difference in TB that is causing this unwanted behavior.

I do not see that there are any settings to change this -- but before I dig too deeply, I want to understand why this change was made and whether I have a choice or setting I can fix this -- or if it's a bug.

Thanks!

I've recently updated to windows 11 and downloaded the latest version of Thunderbird. For the past few days, I'm told that emails are downloading but nothing shows up in my inbox. I can still view my latest emails via webmail but not with thunderbird. I've contacted my provider and they believe the problem lies with thunderbird and not optus. I've also unistalled and then reinstalled thunderbird and the same problem remains. Can you please help? thanks, Rosetta

Copied Thunderbird Profile on old computer to external HDD. Name assigned was zs6…. Installed TBird on new Win10 PC, omitting sign-in procedure. On this PC, clicked Menu, Help, Troubleshooting Info. Opened Profile folder on this PC, left-clicked Roaming, closed TBird. Copied zs6… from ext HDD, pasted onto TBird folder C:\users\owner\appdata\roaming on new PC. Clicked Yes to replace any existing files. Opened \roaming\thunderbird\profiles zs6…. not in there. TBird launches again in Setup. What am I doing wrong?

Since the beginning of July (latest update) Thunderbird cannot download any new emails. When I try to get new messages, it seems to connect to my optusnet email account, then it will say Downloading message 1 of 27 and after about a minute it just disappears. Then it says no messages to download. The little blue progress bar also disappears. I have checked the server settings. I am using Pop Mail Server, server name is mail.optusnet.com.au, user name is my email address, Port is 995, Connection is SSL/TLS and Authentication is Normal password. I have tried turning off Firewall and Antivirus and still not coming through. Its like it connects and it can see the emails but it cant pull them across. I am not a computer person. I dont know how to check any more than this. Please can someone help me. I have been using Thunderbird for many years and this issue has happened in the past but always resolved itself. TIA

I'm trying to better understand how Thunderbird communicates that messages are deleted to the servers of the respective email accounts configured as IMAP. Specifically, it seems that when moving a message from an IMAP folder, such as an Inbox, to a folder of a different email account or a Local Folder, the message disappears from Thunderbird but doesn't immediately get deleted from the server (I am checking by logging in through a browser to the email's web interface). Depending on the email provider, it may be marked or flagged as "deleted" or in some cases it just remains in the inbox (in outlook's web interface, for example, I can't tell if a message has been marked as deleted or not). Only later, after right-clicking on the respective inbox in Thunderbird and choosing "Compact" it deletes the message from the server.

I'm a bit confused now: All of my accounts are using maildir (https://support.mozilla.org/en-US/kb/maildir-thunderbird) as storage format, which I selected prior to adding any account. According to the information here (https://support.mozilla.org/en-US/kb/compacting-folders), "Compact does not apply to accounts using the maildir storage format". So for maildir accounts, why do I have a "compact" option at all and how come it doesn't delete messages immediately? Or perhaps I'm misunderstanding either what compact means or maildir or (probably) both? Is there a way to have Thunderbird simply delete (not just "mark as deleted") moved messages instantly?

I was under the impression that since maildir stores essentially one file per email message, that it would function like file management on a computer, so when moving a message from folder A to folder B the file/message would disappear from folder A, not that it would keep a copy "marked as deleted" in folder A. If anybody could explain this I would be most grateful.

I got a new PC with Windows 11. I installed Thunderbird 136.0.1 , activated the private calendar, and entered events there. For events with a reminder that have a specific duration (e.g., Wednesday from 10 AM to 11 AM), I receive notifications. However, when I create a full-day event and want to be reminded, for example, 1 day before, I don't receive any notification. Additionally, events with a reminder are not shown in bold in the calendar overview (whether they have a specific duration or are all-day events). Can you please help me?

The archived emails have disappeared from my folder, and I can't find the archive location. There is no reference to any archive in All Mail, where Settings is set to store the file. I've looked at all other folders, including Local, but find nothing. Searching for Archive gives nothing.

Hi, Win 10 Pro new installation. Dell Optiplex MBR type Bios.

I had saved a recent profile to an external drive in its own name (i.e. not the profiles folder)

After the new Win 10 installation, I downloaded a new copy of Thunderbird.

I then copied the saved profile into the new Profiles folder, selected it in Choose user profile and started Thunderbird.

Thunderbird opened but not with the saved (8+ Gb) profile, just one new email account and asking for passwords to other email accounts I used before, and no folders.

I went back into the profiles folder and renamed all other profiles "OLDxxx999, but still the same one new email account when I opened Thunderbird.

I desperately need the saved email folders - I don't mind loading all the email accounts again, just need my court case history folders.

How can I force Thunderbird to use the saved profile, or can I identify and individually load in the saved local folders?

Thank you for any guidance towards a solution.

Bonjour, Thunderbird a interrompu la connexion d'un compte email Orange d'un ami. L'adresse et le mot de passe de messagerie sont corrects (ils permettent d'accéder au compte en ligne). Thunderbird n'arrêtait pas de demander le "nouveau mot de passe" et le rejetait constamment. Nous avons d'abord essayer de supprimer, puis ajouter le compte. Cela n'a pas marché. Nous avons désinstallé puis réinstallé Thunderbird. Puis, nous avons tenté d'ajouter le compte (avec protocole IMAP 993 SSL/TSL mot de passe normal et 465 SSL/TSL mot de passe normal). Cela n'a pas marché. Nous avons redémarré l'ordinateur à chaque fois. Que pouvons-nous ou devons-nous faire? Merci d'avance. Cordialement, Hélène RF

Hello, Thunderbird has interrupted the connection to a friend's Orange email account. The email address and password are correct (they allow access to the account online). Thunderbird kept asking for the ‘new password’ and constantly rejected it. We first tried deleting and then adding the account. That didn't work. We uninstalled and then reinstalled Thunderbird. Then we tried adding the account (with IMAP 993 SSL/TSL normal password and 465 SSL/TSL normal password). That didn't work. We restarted the computer each time. What can or should we do? Thanks in advance. Best regards, Hélène RF

Hello!

I'm in the process of migrating from Evolution to Thunderbird, but I seem to have hit a snag. In Evolution, there is an "Archive" folder, which any archived messages go into (attachment 1). This same folder also appears in K9 Mail (my mobile email client), and similarly is treated as special. In that first attachment, you can also see the "Archives" folder created by Thunderbird, which Evolution does not give any special treatment to.

However, in Thunderbird, the "Archive" folder is completely absent, both in the folder listing on the main page and in the "Copies & Folders" settings where an Archive folder would normally be selected (figure 2). Notice that the "Archives" folder is still present, and is now given special treatment, but the "Archive" folder is absent. Checking the contents of the "Archives" folder confirms that it doesn't contain the emails which K9 Mail and Evolution have been archiving.

Is there a way to access those archived emails from Thunderbird?

Thunderbird Version: 128.12.0esr via Flatpak OS: NixOS 25.05 Email Host: migadu.com (IMAP)

Happy to provide any more info if needed!

Thanks!

Hello,

is it possible to set the width of the columns in Thunderbird Task section using the userChrome.css? If so, what are the CSS commands for the columns?

I ask this question because with the help of the userChrome.css is it possible to set the width of the columns in the email list, like so for the "Date" column:

1. dateCol {

max-width: 112px !important; min-width: 112px !important; }
