Thunderbird Support Forum

I'm about the 100th person to have this problem, so I have spent the better part of two days looking at all the threads and possible fixes. Like all the others, with no warning, my TBird stopped being able to send messages through Spectrum. It did NOT start immediately after I updated TBird to 115.9.0 (in March) but just three days ago. I have three roadrunner addresses in TBird, and one other one associated with a website I have. All have the same problem. My phone and my iPad send messages just fine.

I tried all the fixes that worked for some. They didn't work for me; I continued to get various, inconsistent Send Message Errors. I have come back to the recommended Spectrum setup for the outgoing SMTP server: mail.twc.com, Security is STARTTLS, Port 587, Authentication is Normal Password, my username is my email address. Of course the problem is not fixed.

What DID work was putting TBird in Troubleshooting mode, using the Spectrum setup above. While that is adequate, I would much rather find out what is wrong. I have Matt's 10/7/23 11:56 AM answer to someone, asking for the Troubleshooting Information. I will be glad to supply that but I need an answer to this message in order to do that. Thanks! Demaris

I have a folder set aside for a non-profit I volunteer for. I want to backup all those emails separately so that they are 'easy to access' - it's a regulation. How??

Hello, I got a tale of two computers with Thunderbird on both. First, I will start with my HP Laptop, its my primary computer due to its speed. I went to check my emails this morning. I double click on the TBird icon on my desktop. It does not open. Waited a few seconds, tried again and again. Finally, a folder containing pictures opened up. Then, I went to open FireFox, and that same folder with pictures opened. I tried this like five times and the same thing happened. Then I got to thinkin, when I went to shut it down the other day, it said "update and shut down", so I did. Now that I remembered the update, I decided to go back in time to when the laptop was running real good. So I did that recovery, in doing so, it wiped out some of the applications I had on my computer, such as FoxFire, Thunderbird, Adobe, HP printer, CCleaner, and probably others that I seldom used. Somehow, I got to the point where I reinstalled Thunderbird. The only thing is, it would not let me in. When double clicking on the icon, it took me to a page that just wanted my name, email address and password. I enter the info, that page stayed open and added a few more items to the page, such as IMAP and POP3 stuff. IMAP was already selected by Tbird. I then had the option to click "done" . In doing that, it said "Unable to log into server. Probably wrong configuration, username or password" So there's that. Cannot even see the email program. Second part of the mystery, I have an old Gateway desktop. Its slower than slow. I only use it in emergencies, as the above scenario. I fire it up, wait about 5 minutes before I open Thunderbird on that. Guess what, it wants a password. Whats different about this deal is that the email opens, and I can see all my previous emails, but cannot receive or send. I have no Idea whats going on, unless its my deceased wife coming back to haunt me...I don't know.

4 of my many T.Bird email folders somehow lost their email contents (about 50 emails). I have an older T.Bird email backup and want to only reload the 4 empty folders using the backup. I want to keep any emails that may be in my other current folders but not in the backups. I am not sure how to do this.

If I copy the same named T. Bird email root directory [b0mdofvn.default] back up folders into the current email root directory, I see the replaced emails very briefly and then they self delete, leaving the folders empty.

How do I fix this?

We have been using Thunderbird with a Cox email account. Cox has just transferred all its customers to Yahoo. I want to use Thunderbird with Yahoo. How do I set that up?

When I am deleting emails, I frequently end up with the same email as most recent in my inbox and thus automatically selected. This opens a new tab with the same email as content and soon my tab section is filled up with multiple versions of the same few emails and the inbox tab pushed off the screen.

Can there not be a setting to open up the existing tab if it has the same content. Or alternatively a way to pin the folder tab (normally inbox) on the left of the tabs permanently.

Other tabbed applications do not open up multiple tabs with the same content.

Yes I could shut the unwanted, repeated tab each time Thunderbird opens it, but I don't want to have to.

This seems like an easy feature? Please??

I have cox comm. for internet and emails, they just changed their server to yahoo.com. Now I cannot sign into thunderbird to send or receive emails.

Good afternoon,

I recently installed Thunderbird, and it worked fine for a little while. More recently, I have been having problems with it. One of them I was able to fix after some research and trial-and-error (which was Thunderbird not letting me log into my Comcast/Xfinity email account), but this second issue is confusing. I had to remove the account to get back into it (during the first issue), so I'm guessing that must have caused this (second) problem?

When I went to check my filters/rules today (since I receive significant amounts of spam), I was shocked to see that my filters list was empty (I had about 30 or so filters in place before the first issue occurred). I'm guessing there's no way for me to get these back, and so I'll have to manually reinstate each filter "by hand"?

If there is any way to do this more easily, I would greatly appreciate it. Thank you in advance for your time!!

Hi, I am not sure how it happened, I am now in a position where I can't use my Thunderbird properly. Every time I open TB, it asks for "please enter your Primary Password" which I don't have/deleted? If a try to remove the tick from "Use a Primary Password" it opens a box requesting my Current Password, I have tried the last one and the one before, none are accepted. When I search in Saved logins, it seems to me to be empty. in short I seem to need a current password to change my password. It is a vicious loop. Can any one help sort this out, Please Thank you from Ilio Pieroni

How do I do this? Cox Communications is divesting itself of Email. Thunderbird is my client for my Cox email. It appears Cox has a data package which I need to import to Thunderbird or Mozilla and i need advice on how to do this? I am at wits-end on this issue, I would like to keep chaz4@ cox.net and ocal9@cox.net or switch them to mozilla.org or at least for a while forward them to chask14@yahoo.com. But if non of these things are possible, I guess I will have to stop using either email address. If you are a Human and not a machine, please send your response to chask14@yahoo.com as chaz4@cox.net may not be working anymore.

Yesterday I downloaded Thunderbird to Windows 10 (64-bit), added my Office 365 (for work or school) account, rocketmail account and iCloud account. I created unified folders for the three accounts. I have downloaded the TBSync add-on with the required CavDev (?) one to connect my iCloud calendar.

After successful use the first few times, now Thunderbird becomes unresponsive within 5 seconds of opening, every time, rendering the program unusable.

Troubleshooting mode does not fix the problem, so I assume it's not the add-ons, nor does starting my PC in Safe Mode (F4 at startup ie no networking), so I assume it's not antivirus.

I uninstalled Thunderbird and re-installed from the website today. All my accounts were there (so I wonder if the uninstall didn't work properly, although I assume that it's just the files left on my computer that the new Thunderbird installation is accessing).

All these attempted fixes leave the problem unchanged: the window freezing within seconds of opening.

Because the program becomes listed as 'not responding' and greys out on further clicks, I have to hard-close the program using Windows, selecting 'Close the progam'. Clicking 'Wait for the program to respond' leaves the screen greyed out, and nothing changes for at least 20 minutes (the maximum I've tried waiting it out). This also means that it does not yield a formal crash report, because Thunderbird does not recognise it has crashed.

On one occasion it did create a crash report, which I submitted. I am not sure what behaviour allowed this to happen, and I have been unable to reproduce it. That particular crash ID was as follows:

Crash ID: bp-41096385-eebe-4ccc-a47e-f76300240417

Any help much appreciated! I'd love to stick with Thunderbird if possible.

After the latest update, Thunderbird does not open. On line instructions say to erase some programs in it's file location. Did that, and the program booted. However, today, it will not open again. Can you fix this issue with another release, or should I try to go back to the previous release? If so, how to go back to the previous release without losing all my set up? It is not practical to have to erase those files every time I want to check mail. Thanks, JT King jtking@zoho.com Catdoctor12@gmail.com

when I try to send an email you ask for a pass word for jojack@dslextreme which I havent had for years
