Thunderbird Community Forum

I was in the process of searching my files to attach one to an email when the attachment window suddenly expanded from approx 50% of the screen to almost full screen and I can find no way to reset it. I can see the sideand bottom edges of the window, and move the expand/contract arrow on the cursor to these sides and the bottom corners, but it does not operate, and there is no button to minimise or adjust it. I have just checked and it is operating perfectly fine on both Firefox and the main Thunderbird window, and email viewing windows. Is this a change to the program settings - it appears to only apply to the "Attach" setting - viewing attachments and emails are as they always were.

1 How can the list "recent folders" in the icon "store in" be sorted alphabetically? (sorry, my version of Thunderbird speaks German) It used to be alphabetically, but now is sorted chronologically.

2 I cordially suggest to add a function exactly like this one, but with item at my own disposal (maybe the favorite folders).

Thanks, Martin

Overnight, while computer was sleeping, Thunderbird appears to have forgotten the email password. A dialog box pops up when checking email "login to server pop.centurylink.net with username {correct email address displayed} failed." With options retry, enter new password, and cancel available. Retry simply loops back to this error. Entering the (verified) correct password has no positive impact at all. Program and computer rebooted, no change. Windows 11 Pro. Password was not recently changed.

My Windows 11 laptop became corrupted and the os had to be reinstalled with Microsoft's help. In the midst of all this I did not think of backups sadly. After the restore I started to put my apps back on and without thinking, I installed Thunderbird. I realized immediately my mistake when I saw only new email and no local folders.

The Windows restore created a windows.old directory and I see my profile and configuration files in it. I want to use those old files but I don't know where to copy them exactly. There is some confusion on my part about where the startup is happening for Thunderbird. I really need to have access to all my old mail and local folders.

I'd appreciate any help in this matter. Thanks, Sue

Hi, TB will not retrieve POP mail since 12/19/25; IMAP on same accounts fine (smart phone, notebook, etc.).

Host email server says no changes, and I have made no changes. Odd. *Something* obviously "changed", and only affected POP collection. Kindly, does anyone have an idea as to what variables to pursue?

Win 11 (all latest updates), TB latest update (140.6.0esr), no 3rd party VP, etc.

Thx in advance, Tom

I am using an email server that currently is using certificates that have expired. That problem is being worked on. In the meantime, whenever I access the server to open a folder, I get a pop-up notification telling me that the certificate has expired. I go ahead and confirm the security exception and check the box to permanently store the exception. Trouble is this ISN'T being persisted, when I open a different folder I have to go through this process again in order to access my emails in that folder.

Me thinks you got a bug in your software Kemosabe!

ich kann von Anfang Dezember an nicht mehr auf mein Arcor Mail zugreifen äh der sagt der Server ist nicht erreichbar habe schon alles versucht hier mit Windows 7 ist der PC ich habe zwei PCs mit Windows 7 und beide gehen nicht nur am Windows 10 habe ich wieder hinbekommen aber Windows 7 Minuten ich bin schon am verzweifeln oder geht das nicht mehr in Windows

A couple months ago, I asked internet provider to discontinue service. I continued to get emails from their server anyway. In fact, I think I am continuing to get some from them but appears they maybe forwarded to my gmail address instead of iowatelecom.net address that I was using. Now, when Thunderbird downloads my emails, first thing that pops up is a message saying "The certificate for imap.iowatelecom.net is not valid for that server. Someone could be trying to impersonate the server and you should not continue." Then, it gives me the little box with "Dismiss", that I can check. It will go ahead and download my emails into the gmail folder. The iowatelecom.net folder is in RED and no emails are going to that folder. Can I or should I get rid of the iowatelecom.net folder and if so, how should I proceed. Just don't want to mess everything up. Thanks for the help.

Have TB on my laptop (146.0.1 (64-bit) on Win11) all set up the way I want it. Would like to "clone" those settings/profiles to my desktop. AI site said, "Copy profiles folder and profiles.ini to the new machine." Didn't work. Asking me to set up from scratch. Laptop is on "standard" edition, think desktop is on beta. Is that the problem? What do I need to do?

For some unknown reason my Karoo account suddenly refused to open and allow mail in or out. I have continually tried all all karoo's advice and getting nowhare. Please help. Campbell Whyte

Hi there,

I'm looking for a mail client, which works portable. Unluckily the Thunderbird editor is real bulls... crap and miles far away from all other mail clients nowadays. All modern mail programs can handle different font types, colors, they all support different font sizes like 8, 10, 11, 12, .... point text hight and having tools like copy formats (mostly a brush) for easy formating.

Some years ago I was using an addon, which added this feature in some parts. I don't understand, why those features are still missing. Today we have 2025 and the time of plain text mails is history since 10 years.

The rest of Thunderbird is really great, especially the portable version.

Questions: 1) When will Thunderbird provide powerful and state of the art formating stuff? 2) Is there an addon which adds powerful and state of the art formating stuff?

Cheers, Kay

Hello from France,

Copying Thunderbird .eml messages to a USB drive formatted as FAT32

ASUS PC, Windows 11

Directly copying a Thunderbird message via "More" > "Save As" to the USB drive works normally.

However, if I try to copy the same message that was previously copied to any folder on my ASUS Windows 11 PC, I get an error message that says:

“This file has properties that cannot be copied to the new location “

Please help me resolve this issue.

Have a good day.

Bonjour, Lorsque je me connecte, j'ai un message que me dit : User is authenticated but not connected et ceci sur toutes mes boites mails. De plus, suite à un changement d'ordinateur mes mots de passe sont visibles aves des chiffres et des lettres "1//03csgEnBPtxsaCgYIARAAGAMSNwF-L9IrjQQom22l5sXSkYLP1h4BvsYHGmRYh43NZEdtoe " Je ne peux pas voir mes mots de passe enregistrés Je ne peux donc pas me connecter à mes boites mails car les mots de passe ne sont pas valides A savoir que je suis sur certaines boites mail sur @outlook.com (anciennement dbmail)

Pourriez-vous m'aider à débloquer le problème car je suis très embêtée Par avance merci et bonne soirée PS : Si je supprime l'application et que je l'installe de nouveau, vais-je perdre tout l'historique (dossiers, agendas, contacts, etc ...)

I've been using TB for years. Recently, I uninstalled it to try other mail clients. I decided to get TB working again but I'm incredibly frustrated that I'm unable to get an outlook.com account and my nexamortgage.com account working. The NEXA account is google based and is usually quite easy. I also have a Keller Williams account that is also Google based and that worked fine on TB just before I tried to setup my NEXA account. I have tried to enter both manually and have tried multiple different IMAP, SMTP Port settings and Server settings, but nothing is working.

From the menu View - Folders - Tags i can view tags in the side bar, which is very helpful. My problem, as you can see in the picture i'm attaching, is that tags are not sorted according to the greek alphabet. Is there a way to sort tags? I'm aware that the first 9 tags are presets.

From time to time especially when I make a break and the screensaver starts Thunderbird crashes. There is a split between the taskbar of Cinnamon and Thunderbird. The program doesn't react anymore. The only way to use it is to kill it and start it again. I really don't know why this happens. It is a new phenomenon. Here are my Systeminformation: [code] System:
