Thunderbird Community Forum

I've been using Thunderbird for my email for many years with no problems at all that I can remember, but all of a sudden, just in the last couple days it has become very, very sluggish to respond to clicks and commands. So far as I can know, I've not done anything that should have caused this to happen. Any ideas and/or suggestions?

From my inbox I normally highlight any emails I want to send to trash and press the DEL key. This morning when I tried to move these across I got a message advising that if I continue it would remove all files from my trash folder. My server settings are move them to nominated folder - see attached. How can I delete from the inbox and transfer to the trash?

The second problem I encounter is whenever I attempt to log into my Thunderbird account I am directed to go through the "Create an account" process as if I don't have an existing account???

This evening, Thunderbird has updated to the new version (can't see where the version number is held, unfortunately). Whenever I try to download new emails, I now get the message "Error with account [email address]. Sending of username did not succeed. Mail server pop3.iomartcloud.com responded: Mate, the command must be one of CAPA, USER, PASS or QUIT." Mails are still accessible through the mail client on my phone and through webmail, just not through Thunderbird.

I suppose the best place to start is when/where I think this problem started. Approx three to four weeks ago my thunderbird program stopped downloading emails from my server (Spectrum/RR). I say Approx because the problem sort of sneaked up on me without me realizing it was there.

I was using W7 and my hard drive was pretty much full and I was constantly getting messages that my email could not be downloaded due to lack of space. I started deleting stored emails and emptying the trash, which sort of kept me up and running for the past couple weeks. All this time my Gmail account continued to work as it should, downloading every email that was sent to me, but the Spectrum/RR account was spotty at best.

So today I fired up a new W11 computer for the first time. One of the first programs I installed was Thunderbird. When I attempted to set up an account using Spectrum/RR the process failed. I typed in all of the correct information, Name, Email, and Password but the account will not finalize. Instead, I continue to get the same message that the Configuration, Username or Password is incorrect.

I have since successfully logged into my Spectrum/RR web mail, so I know the username and password I am using is correct. I have also talked with Spectrum Technical support, and they have verified that what I am using to log in is correct.

I hope I didn't ramble on to much and someone can help me !

'Have enabled and disabled. restarted, both times. Tried troubleshooting mode, and cleared the cache. Could not find the setting in the config screen. Not sure I was looking for the right thing, anyway. Your help will be greatly appreciated. John Looze

I am currently on Ver 115.12.2 (32-bit), but I've had this problem over several versions. I recently downgraded from the 64bit version (for a different reason), it had the same issue.

Old messages in the Inbox are listed twice, including those that have been read. New incoming messages are not duplicated, messages where I've deleted the duplicates are not again duped. Messages that get filtered to or moved to folders are not duped. Old messages that are in folders are not duped.

I have several email accounts in TB, and I only see this on my most active- of course! I have compacted all folders many times and rebuilt the Global Database with no effect. I tried opening in Troubleshooting mode and they are still duplicated. It is a POP account.

Last night all my messages current not received and saved and received disappeared. at one time my pharmacy came up but when I got out and went back in they disappeared, I did try to empty basket on junk mail but couldn.t

Background: I've been using Thunderbird for desktop for a couple of years now, and had no trouble with it. I use it to connect to email inboxes from a hosting provider. In the past, one of them was going through Google Workspace email (linked to my own domain), but I decided to go with Thunderbird instead. I did connect to Gmail once (if I recall correctly), to download emails from there. Then, all the mail server settings were set to those of my hosting company/my domain and worked well.

Today, after starting it up, I received a notification of a Thunderbird update (new looks, new nesting of connected emails, card-like look of emails), and I received a prompt to log in to the long-defunct Gmail account. I closed the window and went searching for the reason. All my mailing server settings seem to be fine. In the Thunderbird settings, in the Privacy&Security tab, Passwords section, I found several saved passwords relating to said defunct account. I deleted them all in hopes of solving the issue. Unfortunately, this only changed the prompt: from asking me to sign in to the specifically-named defunct account, it's now asking me to sign into Google account in general while the popup's header still refers to the defunct account. I also went ahead and downloaded the newest update. My Thunderbird seemed already updated judging by the version number, though none of the new features seem to be enabled, and some note mentioned that it's not an automatic update but one that had to be downloaded. Unfortunately, it didn't help either. The PC had been restarted. The pop up appears shortly (~1 min) after the startup, and then at random points of Thunderbird being open.

I'm out of options and at a loss of how to get rid of that constant pop up, and I feel like I'm missing something obvious. I hope someone here might help.

After downloading TB128.0.1esr (32-bit) the following error appears continously"

Authentication failure while connecting to server pop3.live.com

This was not an issue before this download!

Booted my computer this morning and eventually Thunderbird. New mail downloaded, but does not appear. All messages gone from midnight to 11:53 AM. Messages are on the server, but not my client.

I just updated Thunderbird to the latest version (128.0.1 esr 32 bit), and now a repeated event shows all of the repeats in the list. Is there a way to remove that from the list? I liked it better the old way.

I'm no longer able to signon to Thunderbird on my laptop. I can signon to gmail.com server to view email. 2 iPads and 2 iPhones also provide email. Just can't get Thunderbird signon to work on my laptop. I suspect this somehow involves Google. When I try to get msgs in Thunderbird, a panel pops up "Enter credentials for Google". Message indicates Signin to continue to Mozilla Thunderbird email. Then asks for a password. What password? Google or Thunderbird? Neither works. Not sure what to try next. Any help would be appreciated.

Dzień dobry, mam problem ponieważ komunikat z załącznika pokazuje się co minutę , oraz przy każdym wysyłaniu wiadomości muszę się logować. Utrudnia to pracę. Proszę o szybką odpowiedź i naprawę.

Hi, I'm running into the issue where I have a public certificate issued to security@companyname.tld as they don't issue a separate one for most employees, but Thunderbird won't let me use it for sending (I think it's used when replying?) it to firstnamelastname@companyname.tld

Is there a way around this?
