Email errors started occurring on or about November 25, 2024. Multiple calls and tech support with Spectrum techs and hours of troubleshooting brought about O results. I obtained all necessary protocols for configuring email to Spectrum requirements and for sending and receiving, but I still get outgoing errors. I have been using Thunderbird for 5 years or more now and never had any issues until now. Upon inspection through Thunderbird tools/setting/ looking at "SAVED" passwords, I no longer see "IMAP" or "MAIL" access protocols. It was there previously. I also disabled all my firewall and vpn settings and still cannot send out any emails. I have thoroughly checked out both my personal email setting and my small business email settings and everything as it relates to Spectrum is correct. Spectrum said one thing they found was that the email settings (specifically, would not resolve with the server because of a syncing problem). Spectrum did all they could to resolve on their end, but the issues, as they see it now resides on the Thunderbird side. In an effort to resolve the issues, the Spectrum tech looked and looked for a phone number for Thunderbird and said this is the first time he has never found a number that one can call for some sort of assistance. Emails directly to Thunderbird are very, very slow. And to compound the issue, there are no lists I could find is a repository for error codes and no valuable tech support or specifications could be found that provides any real help for resolution. So now I am making a last ditch effort to contact Thunderbird for a one on one phone conversation that will resolve all the issues I have encountered. Hopefully with your immediate reply, we can resolve these issues and I will be able to help others resolve these same issues. These issues are not just isolated to me. There are literally hundreds maybe even thousands of people out there with the same issues. PLEASE contact me asap. Thank you for your time. (PS. I do receive some messages via email, but sending out is the issue)

Dear Mozilla, My 27" iMac crashed suddenly on Wednesday last week (when I wasn't actually using it) and would not boot up. A message referred me to Apple and I made an appointment in Glasgow to take my Mac for the repair. I plugged my Mac in before I left - and it recovered itself!

However all my Thunderbird emails, files and settings have totally disappeared! Apparently a Thunderbird update is responsible. I have spent hours on the phone trying to get help. I have spent hours with CHATDGP talking me through stuff. The data seems to be on my machine but whatever I do I can't get Thunderbird to work. I am at my wits end. I have all my work files in Thunderbird and have no access to anything.

This is the second time recently that my Thunderbird files have vanished. I had to pay an expert to come to my house and restore the first time, but he is very ill at the moment and unable to leave home.

Please help me. I would be very grateful to have my Thunderbird back and working correctly. I am on macOS Monterey, version 12.7.6 (21h1320).

kind regards Helen 07836 707504 UK

Ever since the new version of Thunderbird I cannot send emails. I can receive them but not send them. I have found that if I temporarily disconnect my VPN, it sends OK. Your failure to provide software that can co-exist with a VPN without crapping itself is a poor advertisement for your product. I have read some of the millions of posts about this particular bug and your answers seem smug and lazy without addressing the problem.

I am running Thunderbird 128.5.0esr (64-bit) on 2 computers: a lenovo T480s and an HP EliteOne 750 Both are running Linux Mint 22. Both use gmail with the same config.(see pic). Comcast is my ISP

Problem If the computers are connected to my router by ethernet cable both can send emails

If I use WiFi neither computer will send. The "send" popup just spins.

I can send gmail from my iphone over the same wifi network

I tried hooking the computers up to a hotspot from my iphone; neither will send

Any ideas?

The global search in TB is completely defective. I am now running 128.2.0esr and hoped that update might fix it. It hasn't. I just wonder, are there any older or non ESR versions I can downgrade/move to, where the search is fully functional?

Hi all,

I have been having a recent issue with Thunderbird build 115.4.1 (64-bit). I've attached a picture. Every 24 hours or so I have to approve a security exception for my pop accounts. I have the make permanent check box checked but it keeps happening. This has been happening over the last 3-4 weeks. I am using Windows 11 (23H2). I've played with lots of different settings but nothing seems to fix the issue.

HELP

Hej Jeg har i dag prøvet at oprette en ny mailkonto ved thunderbird Mozilla men jeg kan ikke få mit mailsystem til at sende en mail ?? Der kommer denne fejl : (det hjalp ikke at oprette en ny mailkonto) for fejlen er der stadig

Afsendelse af meddelelsen mislykkedes. Der opstod en fejl under afsendelsen. SMTP-serverfejl. Serveren svarede: Client host 80.208.70.116 blocked using SBL-XBL - see https://www.spamhaus.org/query/ip/80.208.70.116 for details.

og nu ved jeg ikke hvordan jeg skal løse dette problem. vores internet udbyder er jubii.dk

In 2016, whilst importing emails into Apple Mail, about 20,000 email were given the date and times of the import instead of the date from the Received Header. Luckily Thunderbird has retrieved the emails from my IMAP server and given them what appear to be the correct dates. Meh knowledge of the tech behind this is very limited. Anyway, my question is, how can I export a fresh mbox or other format of mail folder with Thunderbird applying the correct dates to each of the messages?

Sometimes, when I delete one email from the inbox, the inbox shows "no message found", even though there are still other emails in the inbox. The remaining emails are still in the inbox, they just don't show. If I right click on inbox in the left panel, and select "open in new tab", the remaining emails show in the new tab, just not in the main inbox. If I close out thunderbird and start it again, the emails show in the main inbox. The problem occurs occasionally, whether I select delete from the menu bar, hit the delete key, or right click on the entry and select the trash can icon.

This problem started maybe 10 or more updates ago. For each new update I think "surely it will be fixed this time".

I have included a partial screenshot of what it looks like after the problem occurs.

This problem is different than any other questions I have found in the search. It purely a visual presentation error, not disastrous, just highly annoying. Any solutions will be greatly appreciated.

The bulk filtering stopped working correctly a couple of months ago. Earlier on it stopped spam and I had the possibilty to mark a message as "Not junk", the filter then learned that messages from this sender was not junk. Today the filter is not learning. If it stopped a message and I marked it as "not junk", it´s not learning and will continue to stop messages from this sender.

I get an error when I try to compact the Trash (after deleting emails). I am able to compact all others with no problems. See the jpg image file attached. Thanks. Brad

Bonjour à tous et à toutes, J'ai le message suivant depuis le 28 novembre 2024: "Mozilla Thunderbird ne répond pas, ce qui m'embête le plus c'est que je n'arrive plus à récupérer sur ce poste mes messages envoyés, peut-on les récupérer sur un autre poste ? car j'ai d'autres postes où Mozilla Thunderbird fonctionne. Merci beaucoup de votre aide, cordialement !

Hi, I Changed IMAP to POP3, rebuilt Inbox.MSF and it worked for a few hours. Now, I cannot get control of the Thunderbird screen (it is grayed out and "the wheel is turning") I've also tried to Shift click to start Thunderbird to start in Troubleshoot mode and checked both boxes. (I get control for approximately 15 seconds). I am running Windows 11 with 128 Gb of RAM and enough disk space. What should I do now?

BTW, I am an I/T professional, so you may use jargon in your response.

Thank you in advance.

Just wondering.... If I have 2x email addresses, and forward a message from Email#1 to Email#2 (ie automatically through the settings on the email#1 account), when receiving in Thunderbird, would, or should, this info show up in the full headers of Email#2, and if so, how?

Thanks.

I have a recurring problem with mail becoming stuck in my Outbox. The symptom is that I discover, after hours of working, sending mail, and receiving mail, that the "sent" mail is all actually stuck in Local Folders Outbox. If I click on Outbox I can see the email messages that are waiting to go out. The only way to get them to go out is to quit Thunderbird and then restart, at which point I can see them go out, one by one.

This has happened to me many, many times, but not every day - or even every week. It's hard to pin down what what is causing the problem, but I have a feeling that it is vpn related.

My normal mode of operation (on a Macbook Pro) is to switch back and forth between home and work networks (or travel networks) without logging out or quitting tasks (including Thunderbird). I don't think that's the problem. While I am working, I frequently have to switch to an internal vpn to access various things. I don't like to run video conferencing or other high bandwidth tasks through the vpn server, so I generally disconnect when I don't need it. I *think* Thunderbird is sometimes getting confused about the network - perhaps when I've started composing an email with vpn running but switching vpn off before sending. Honestly, though, I think I do that so often that this can't be the core issue. So:

Question 1: Has anyone seen this and found a solution?

I've tried just writing a cron job that watches the file "Unsent Messages" in

/Users/myname/Library/Thunderbird/Profiles/[profilename]/Mail/Local Folders

I just check to see if there are messages in there, and send myself a notice. However, this doesn't work because that file doesn't actually seem to empty itself once messages go out. It doesn't save all outgoing mail, but it saves a bunch, so my trick won't work.

Question 2: Does anyone know why the Unsent Messages file doesn't clear once the messages go out?

Question 3: Is there some other indicator that I can probe to see if there is stuck outgoing mail?

Sorry for the long description. I wanted to be as complete as possible. Thanks for any help.

I allowed windows (11) to apply updates. Afterwards, my Thunderbird email cannot see the email in any folders except only unopened email in inbox. The data still seems to be in the files.

Spent 2 hours with Dell support, who were unable to resolve and they say it's due to Thunderbird, which re-installed itself (?) around the same time as the windows update.

Any help? Thanks.
