Thunderbird Community Forum

bonjour, J'ai installé un nouveau profil, mais j'arrive pas a utiliser l'icone -sélectionner messages à droite au dessus des mails- appliquer ces paramètres/la vue... Ca me serai utile pour simplifier et unifier mes affichages. Actuellement j'observe aucune changement, bug ou erreur de manip.

Starting today (September 3), ALL of my received emails are being put into the Spam folder instead of the Inbox.

FYI, I have been running Thunderbird (TB) for years and have not recently set up any new filters.

I'm currently running Thunderbird 64-bit version 155.0 under Windows 11 Home version 25H2. I am also running Bitdefender Total Security, but I have turned off its Antispam function, both under my usual Standard User account and the Admin account.

I have tried:

1. Going into TB Settings|Privacy & Security|Spam and clicking on "Reset Training Data." 2. After closing TB, I deleted the training.dat file in my TB profile folder and restarted TB. 3. Right-clicked on my Inbox and Spam folders and clicked on "Repair Folder." 4. Exited TB, copied my profile folder to an external HD, uninstalled TB and reinstalled TB after downloading from the official download site. 5. Rebooted my PC.

None of these approaches has worked to solve my problem.

Thanks for any help you can give.

As of noon yesterday my Thunderbird gets messages, puts them in the trash, then the spam and then sends a message to "spam" at my email provider. Since noon yesterday, I don't get email messages. I don't know what else it could be. If I go to the webmail, I get messages, but as soon as I download them with T-bird, they are in the trash and then sent as a spam notification to my email provider. I really use t-bird a lot so I would really hate to stop using it, it's much more useful than the webmail. Thanks

PS. I use Linux Ubuntu

Good afternoon

I have been struggling to find some messages specific to specific dates and spend an awful amount of time tryomh yo access the correct one.

The solution proposed is a bit unclear to me, as it refers to "future folders". I need to unthread all my messages. Is this possible?

Thanks

PS The only version number i could find was for Firefox. There does not seem to be one for Thunderbird.

I have what should be a pretty simple question. 1. I deleted my Tbird POP acct because it stopped working. 2. I reinstalled it. 3. My saved mail folders were gone. 4. Is it possible to get them back? 5. * This question is for someone other than David. 6. I just want to get my old saved folders back into my reinstalled account. 7. It's been about five days since this all took place. 8.The version I deleted was a the previous release.

Maybe I accidentally made a setting, but if I go get email, it sends it to trash and from there marks it as spam and sends it to spam at my email provider. This just started when I tried it this afternoon. I think it was OK in the AM. I use Linux Ubuntu. It moves all emails to trash and then sends them. I just looked at my message filters and they look normal to me, I do have something called SpamAssasinYes, which I remember from years ago that looks at the whole complete header and sends an email to all the providers in it telling them that their user is using their server for spam. Maybe that has changed somehow, but I forgot it was there because it has been there for about 20 years. Should i just remove all those filters and see what happens? I need some guidance. thanks

I posted a question on this forum that I want to delete. I can't find a way to do that. Is there some way to do it? This question isn't really about performance" of T-bird, but about this forum but I was required to make a selection. . . ..

I have Win11, Thunderbird Windows MSIX packagethunderbird-MSIX - 1.0, and several accounts (The box below won't take anything past "Thunderbird Window.")

I'm looking for some way to make a different ring either for one of the accounts or for certain domains or for a subfolder -- any way that I'll know when something comes in from specific domains. The special ring(s) can be for each of the two domains or both of them. Can that be done?

I downloaded the version on the site but I can't get it to accept my password all I get each time is this at the top of the box

Component returned failure code: 0x804b000a (NS_ERROR_MALFORMED_URI) [nsIIOService.newURI]

Just how am I supposed to understand what that means. I would be grateful for any help you can give I've been using Thunderbird for over 25 years without any problems, I had to reinstall Windows and now I've got this problem.

This morning Thunderbird asked me to update which I duly did. Once done all messages started disappearing from inbox. Eventually I found them and moved them back to inbox only for it to happen again

Have now tried 3 times, same result, every single email from Inbox keeps being moved to deleted in Local Folders

All new emails that have come in since appear for a micro second in Inbox before being moved to Deleted

This is obviously not a great situation to put it mildly and as it has never happened before and started straight after this morning's update I can only assume that the update is to blame

Any help would be greatly appreciated

Helping a friend with her HP-i3 PC running Windows 11 that I setup in March of 2025. It was a new PC purchased from BestBuy in March 2025.

I had to restore the image backup of her C drive that I did in March 2025 because of a Windows problem that I wasn't able to resolve. Now that problem is resolved but Tbird has the old profile folder without her new email contacts. (Unfortunately, I did not remember to use Tbird to save a backup of her profile folder before doing the restore.)

She has a recent image backup so I can extract Tbird's profile folder from that backup. What would be the correct procedure to replace the current profile folder with the one extracted from the recent backup?

(don't currently have access to her PC so don't know the version number of Tbird currently installed)

I have "Allow remote content in messages" turned off. However I receive many messages for which I wish to allow it for that message. I do so and it works fine.

What I would like to be able to do is to have TB learn the message senders for whom I have allowed remote content so I don't have to click it every time. Is this a feature that is available that I am missing, or is it just not possible?

If not possible, please advise as I will submit for an enhancement.

This problem happened after the September update. No changes to any message filters. I am not the only one having this problem. What changed in the update that could have caused this problem? I have had to delete the problem account from Thunderbird because every time I move the messages back to the Inbox in Outlook, Thunderbird would move them back to Delete.

Logged into Thunderbird this morning. On current version. Noticed that the local trash folder had emails in it. I have not changed any of the multiple account setting. Send some test emails fro 2 accounts and they ended up in the local folder trash. What has happened. I want this redirection to stop. What other demons have been created by the current update. HOW CAN i fix this problem?

My Thunderbird Account was updated by TB on 2 September. Since then all of my new emails go to Trash. Although I've tried the various responses to such questions, I've been unable to change the problem and get my new emails to come into my Inbox. I'd very much like your assistance please. Thank you.

Since the last (v155) update, TBird started putting all incoming email into one subfolder under my main inbox. I have several message filters that sort incoming mail into various folders. When I disabled the message filter associated with the folder in question, the email started coming into my inbox folder again. The message filter connected to that folder has not been changed in a while, and is a "match any of the following" rule with a number of specific from/contains/[text] entries. When I examined the filter closely, I found two rules where the [text] field was blank, which apparently was causing the problem, but as I said, I haven't changed the filter in a while - what recent change might have caused this? (Either adding empty fields or else considering [blank] to be equivalent to [any].)

This is probably not a T-bird question, per se, but it is so strange it seems that this might be the best place to start, hoping someone might have some insight.

My wife and I each have our own laptops, running Win-11 Pro. Each laptop has T-bird 153.2.0esr (32-bit). We each have an account to yahoo mail (the site now hosting our Comcast email accounts). No problems since ... forever. Until today.

Now, beginning today, on my wife's laptop, when she opens T-bird, she gets a pop-up logon page, pre-loaded with her userid/email address. No input field for a password, but that it not unusual, as a lot of sites put that on a follow-up. But when we click 'next', it just rejects it. We were able to log into the yahoo mail web page (in Firefox) just fine.

After a lot of head scratching, I added her account to the T-bird configuration on my laptop. First time up, it prompted for credentials, but here it accepted them. So now we have her yahoo/comcast account configured and working just fine on my laptop, but continue to get credentials rejected running the same config on hers. Again, this has been working just fine up until today.

(If you are wondering about the connection between Comcast and Yahoo, several years ago we 'cut the cable' with Comcast, after confirming they would continue to support our email accounts. Then some time ago, they off-loaded that to Yahoo, such that we were able to retain our Comcast email address, but it redirected to and is hosted on Yahoo.)

Thunderbird version number: 148.0.1 Mail provider: Yahoo Client OS: Windows 10

The issue and steps I tried to resolve: On 1 Jan 2026 I switched from Outlook client on my Windows 10 PC to Thunderbird 146.0.1. I did not import any user data from Outlook but started with a clean install of TB for the new year. I use yahoo.com with POP3 as my email provider. Server Settings: Server Name "pop.mail.yahoo.com", port 995, SSL/TLS, OAuth2 Outgoing Server: Server Name "smtp.mail.yahoo.com", port 465, SSL/TLS, OAuth2

it all worked fine and I was very happy with the setup. Then from early to mid-February I was unable to use my computer. When I finally accessed Thunderbird again, it connected to Yahoo and showed that approximately 800 email messages would be downloaded and started downloading them. After downloading about 100 messages, Thunderbird timed out and I haven't been able to get it to work since.

I have read and followed or tried to follow these articles plus others that I may have forgotten about (not listed in any particular order) - OAuth2 Authentication for Yahoo, AOL and ATT | Thunderbird Help - including all the steps in Please check the following before asking for support - POP access settings and instructions for Yahoo Mail | Yahoo Help - Automatic Account Configuration | Thunderbird Help - Manual Account Configuration | Thunderbird Help - Thunderbird and Yahoo | Thunderbird Help - Send and receive messages in Thunderbird | Thunderbird Help - Can no longer get emails | Thunderbird Support Forum | Mozilla Support - Emails suddenly stopped downloading to Thunderbird 140.2.1esr | Thunderbird Support Forum - Get Messages | Thunderbird Support Forum | Mozilla Support - Cannot receive messages | Thunderbird Help - Problem with Thunderbird working with Yahoo Mail acccounts. | Thunderbird Support Forum

I have removed all messages from the Yahoo inbox and tried to find one or more messages that may be affecting the download. I don't know the best way to determine that.

I use Windows Defender for my antivirus. I don't see anything in Defender that blocks or scans email messages which would prevent downloads, although I could be wrong about that. if this might be the issue, please provide some guidance about how to check Defender.

I have uninstalled and re-installed Thunderbird. In the process I downloaded the setup file for Thunderbird Setup 148.0 and installed that version. It later auto-updated to 148.0.1. Before installation, I removed all external connections from my Yahoo account and completely removed Thunderbird from my PC, including the profile and profile.ini. When I reinstall and switch the account to POP3, Thunderbird captures the App password from Yahoo and connects just fine. But it still times out while attempting the first download of a message. The first several times it timed out, an error message was displayed but now it doesn't show anything. Except no messages are downloaded.

At this point, I don't know what else to try. Since I don't have much experience with Thunderbird, I don't know how to troubleshoot the process (logs to look at, etc.). I don't want to go back to Outlook but I need the email client to work and download messages. Any help would be much appreciated.
