Thunderbird-mienskipsfoarum

Introduce a way to completely disable anti-spam. It is a totally undesirable and inconvenient feature for many users. I have tried to disable it in every way, but I have not been able to. It has caused me serious inconvenience and damage.

I have been using Thunderbird for over 10 years, and I have thought about replacing it a few times due to this anti-spam issue.

1. I am getting Mozilla Thunderbird ESR notices pop up when I log on to my PC (W11). I checked my Thunderbird version and I have 146.0.1 and I am on the release channel so why am I getting these notices ? 2. Recently I noticed that when I try to move e-mail messages to a specific folder, I right click on the message and get the prompt Move To and then Recent Destinations where the problem exists. The list of Recent Destinations used to be in alphabetical order and now it is sorted by most recent destination time. This slows me down considerably. Please revert. Thanks !!

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?

I'm dealing with a properly updated 'bird: 140.5.0 (32-bit) running on an equally updated Windows 10 desktop. First thing this morning, out of nowhere, I started getting an "unable to write the email to the mailbox..." message when sending, thus I could send but not save. And then I realized I wasn't receiving either, on all three accounts in my Thunderbird. I stopped everything and focused on trying to fix this. It's been an all-day, losing effort. So far.

I tried the various quick checks and fixes recommended here and there: I'm running the program as an administrator. I restarted the program. I rebooted the computer. I think I have enough disk space, but to be sure I deleted some bloat from possibly overly large files. I compacted, even though the program is configured to do that regularly. I temporarily disabled my antivirus program. I went into my webmail and deleted all messages that have arrived since my Thunderbird stopped receiving, in case one of them was corrupted. And probably some other attempts as well. Nothing has helped.

And now a second, even worse issue has fallen from the sky. Thunderbird opens. The folder list is where it always has been. The number of unopened messages in each folder is there in boldface, as always, but...the folders are all blank and I get the dreaded popup: "unable to open the summary file...." Have I lost my years' worth of carefully curated emails?

I've tried folder repair. I've deleted parent.lock. Etc. Nothing. Nothing. Nothing.

I will be super-grateful for any wisdom sent my way.

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.
