After returning from a 6 day vacation, my wife attempted to download email from her Yahoo email account. There are nearly 200 messages that have piled up but they aren't moving. I've uninstalled and re-installed TB. I've uninstalled and reinstalled the app password in Yahoo. There is no problem with accessing the email via any web browser. I spent 49 minutes on a tech support call with Yahoo and they have said the problem is with TB because they repeated the same steps I have. I checked firewall settings and the only antivirus program on the computer is Malware Bytes and it's not running in the background. The version of TB is the most recent as of yesterday. I don't see any sketchy looking emails in the web version of Yahoo Mail when it's opened. It's set up as a POP3 account and has been since Cox Internet gave their email over to Yahoo. I'd appreciate any assistance in resolving this because it's currently above my pay grade and tech support at Yahoo.

Here is the message I get. Very inconvenient... Sending of the message failed. An error occurred while sending mail. The mail server responded: Too many recipients. Please reduce the number of recipients and try again. AUP#Out-1550. Please check the message recipient "........" and try again.

My email works well most of the time. About three or four times a day now I get a message "The current command did not succeed. The mail server for account <account name> responded: System Error (Failure)." Nothing seems obviously wrong that I can see, maybe some of my recipients aren't getting the emails I send? The account in question is at gmail. I've been using it, and Thunderbird, for many years without seeing this error. It seems to have popped up in the last month or two and is now happening a few times a day. I'm running Windows 11 Pro 25H2 build 26200.9168, Thunderbird 153.0.3 Build ID 20260810194242. I have plenty of disk space (1.15TB free) and restarting my system hasn't helped. Is there a way to turn on more logging to get more information about these errors?

In the last month or 2, when I delete an email it does not show in the trash folder. I can wait from 5 minutes to even the next time I reboot my puter to finally see it it trash. Sometimes it sends it to the all mail or important folder instead of trash. And if I delete from there, it still takes tons of time to end up in the trash folder...if it even gets there. This seems to be getting worse by the day. I have clicked repair folder, no change, I have cleared Thunderbird's cache, no change. It's also now taking way too much time to load an email that contains a picture. This happens with at least 3 of these gmails. I'm at a loss here and extremely frustrated and about to change these gmails from imap to pop. win10 and TB is up to date. But it doesn't compact folders as much as it used to either. Any help appreciated

Hi, Hoping I can get some help here, I couldn't find an answer in the search topics.

I have lost a few local subfolders. First the subfolders lost the emails contained in them and then the subfolders themselves disappeared.

I renamed the main folder just removing the year from the folder name and not long after that the above happened.

I have tried the following:

• Searching the help topics • Searching the forum • Closing reopening Thunderbird • I removed .msf files and restarted Thunderbird

I am not sure what I can do now.

Thanks in advance for any help.

When I added a new subfolder it disappeared. When I tried to add it again it just shows up. Today I can't add a new subfolder and the info in the folder I had won't show up.

I have a new PC. I have added five email accounts, three different hosts, with some difficulty. Thunderbird finds the details for others but then refuses with the message Authentication error. Unable to log in at server. Probably wrong configuration, username or password.

I added Thunderbird by copying from my old PC. The hosts for those not yet added are the same as those added.

This is the message I get when it does not go. I contacted Spectrum and they told me to check Thunderbird.

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: p-impout004.msg.pkvw.co.charter.net cmsmtp 73.238.167.193 blocked. Please see https://www.spectrum.net/support/internet/understanding-email-error-codes for more information. AUP#Out-1130.

I have successfully added five ntlworld.com email accounts in Thunderbird but my two personal ones keep coming up with Authentication error. Each time the screen shows the details of the account found automatically so the information is coming from somewhere.

Advice I gratefully received was to Disable the account hub in Settings / General, then add the account from New Account, and use an application specific password assigned via your email provider.

Virginmedia no longer seems to acknowledge ntlworld accounts but says they are talktalk. However, talktalk says they do not hold the accounts.

I do not understand how I can disable the account hub in Settings when it has not loaded.

I cannot understand why two of the accounts do not load.

Thank you for the advice on copying the Thunderbird folder, which I have done. However, what is failing is the adding of further existing email accounts. I enter the Account name, the email address and the password but I still get Authentication error. I have, after some difficulty, succeeded in adding five accounts with three different hosts. The further accounts I wish to add use two of the hosts of the successful additions.

After a keyboard accident I am left with this situation. Lin found the toggle problem with F8. Wxie suggested the password but the password is correct. Thanks to both of them. It seems the problem is the missing M in .com .It might be in the DNS but I don't seem to have anything to try except to try to recreate the account. If I try that I fear I will only exacerbate the situation. I have had this email for many years. This stared 08/08/2026 I have been searching daily for a solution. Like most things digital it is probably a simple fix if you know how. I don't.

Hello,

My internet provider is RCN. For the past couple of months, I’ve occasionally been getting the message, “Connection to server imap.rcn.com timed out.” As a result, I’m unable to receive emails via Thunderbird.

All my settings are correct. Usually, the problem resolves itself within 24 hours, but sometimes, like this time, it lasts longer.

Any suggestions? Best, Magda

Some time ago I went tinto exceptions and put in some unwanted email addys and they were blocked. I am getting unwanted emails tried the same thing, but they are still coming through. Here are some of the emails; contact@news.comoundeesgtream.com contact@news.musteraliteinfo.com

Can you tell me how to block these from showing up in my email account? John @ redacted@outlook.com

Hello Folks, We are a team of 15ppl using thunderbird from last few year and it work flolessly in these years but from last 1week i have been facing a serious issue of : INCOMING EMAILS TAKING A LOT OF TIME TO OPEN AND READ, fresh email when received and after clicking it takes a lot of time of open, having a 100mpbs ILL speed, out of 15 / 12 ppl are facing same issue, even after repairing the inbox the issue remains same, mails are getting downloaded very slowly...we are using google imap server for the same, need help to resolve the same...is it the bug in the latest update 153.0.3 (64-bit) Meadow badge

I am encountering a message of "The installation seems to be incomplete. Please check your hardware and disk setup and/or re-install." when trying to run Thunderbird.

This first occurred on a system that had been working for a while. An update may have been installed.

Here's what I've tried. -

Uninstall Thunderbird (along with Firefox and Mozilla Maintenance.) Checked for Program Files/Mozilla folder (all were removed). Run SFC / Scannow Run CHKDSK Installed pending Windows update. Restarted the System Renamed (essentially removed) Profiles folder Turned antivirus software off Downloaded and installed the latest version of Firefox, then Thunderbird. Launched Thunderbird. Still received the same error..

Any ideas on how to resolve the issue?

Your last update included a Yahoo signup splash screen. Please remove it in the next update. It is annoying and does not serve any purpose other than ccnect me to Yahoo web mail. If I wanted to use that service, I sign in for it. I am content with using Thunderbird. Or at least give me the option of removing it myself. Thanks.

SHello Sometimes, on my iMac APPLE (OS Tahoe), THUNDERBIRD stops opening (message system: not responding ("ne répond pas" in French) There is no problem when launching the application, but issues arise later when returning to it after using other applications (Word, Excel, videos, etc.), THUNDERBIRD tourne en rond et ne s'ouvre plus. I have to close the application (via my Mac's system settings) and relaunch it for it to open normally again. I would appreciate any help if someone has experienced the same kind of issue. VAJP
