Thunderbird コミュニティフォーラム

Other than being slow to download my emails now for a few months, TB was performing well until a week or so ago. Now it also won't open the downloaded email when I click on it and the TB freezes up so I can't close it out. I have tried restarting computer multiple times and it works for one or two emails that I can open and then starts freezing up again. Makes using it almost impossible. I have security Windows 11 Defender only and have had it the entire time when it also worked well.

Okay, so how to be simple. I kept getting a pop-up from Comcast about a latest promotion and it wouldn't go away. I spoke to Comcast about their ridiculous pop-up promotion, it was coming through my Thunderbird email client. That may be taken care of. But in the meantime I tried to delete my main Thunderbird account, I must have done so and now I can't get it back! I've tried everything! I was using an IMAP account, and for my incoming I had imap.comcast.net. For my outgoing I had stmp.comcast.net and the ports were 993 and 587 I believe. Please don't quote me on this. So when I try to create a new email account using the same information I keep getting an "Authorization Error" each and every time!

So....since and while writing this email, the Comcast pop-up continues to pop up, and I still cannot reset my email account. Talk about a frustration level at this point! I would like to keep my Thunderbird email account minus the stupid Comcast pop-up. I just don't know what to do. Please help from anyone who can!

Thanks,

Michael....

Starting yesterday for no apparent reason TB has been unable to connect to my email accounts. (IMAP or POP). These include Roadrunner, Gmail and Outlook.

Any Ideas? James

I just want Thunderbird to show remote images automatically without me clicking the button. Just show all images. The setting you ask me to change does not exist.

Cannot send or receive email all of sudden in Thunderbird. When I the click the messages icon, nothing happens, and I get "Could not connect to server mail.twc.com; the connection was refused". When trying to send a m,message I get "Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again." No settings were changed and everything was fine when I put the computer to sleep. This happens on both a Win 7 and 11 machine Email is a Time Warner (now Spectrum) Road Runner account (twc.com). Spent an hour with Spectrum, and they say this is a third party (Thunderbird) issue. A friend has the same setup, and is having the same problems that started at the same time. Win 11 version 150.02 Win 7 115.18.0 (latest available for win 7)

Appreciate any help....

Not sure what has happened to my PC but lost my Thunderbird app.

Reinstalled but cannot get my emails working again. I only get emails up to 13th May 2024; I guess when TSO Hosting finished?

I am now on 123 Hosting.

I have a note that SERVER for both i.e. Incoming and outgoing is:-

sxb1plzcpnl503269.prod.sxb1.secureserver.net (smtp as prefix)

Where and in what format do I enter theses server details.

I think I also need to get into cPanel but the URL I have will not work:-

https://sxb1plzcpnl503269.prod.sxb1.secureserver.net3 (:2083)

Sorry but I am confused; don't get old!

Yesterday I was having trouble sending emails from one of my email accounts. I had not fixed that when I shut down for the night. Today when I turned my computer on, both my email accounts and my address book was gone

Français: Bonjour, Presque tout mes icônes dans la barre des tâches, programme ouvert, sont bleu. Comment changer directement la couleur de l'onglet de Thunderbird dans la barre des tâches de Windows. Ce serait bien de pouvoir choisir pour retrouver facilement Thunderbird et lire mon courrier. Christian

English Almost all my icons in the taskbar, for open programs, are blue. How can I directly change the color of the Thunderbird tab in the Windows taskbar? It would be great to be able to choose so I can easily find Thunderbird and read my emails.

I'm trying to re-establish my Thunderbird account after having to re-install Windows. I get to a screen titled "Account Hub" that asks me to add my e-mail address and password. I don't have or recall a password and the screen does not allow an option to recover a password or create a new one.

I'm getting "Thunderbird can't connect to the server" message, so I can't download messages. However, a message or two will finally download 1-2 hours later.

Same problem on 2 laptops, both running Windows 11. But I know my emails are coming in as I can view them via Spectrum webmail. So the problem isn't the Spectrum servers.

I've logged out and back into Thunderbird, and have re-booted my laptops. No luck. What to do?

Also, is there a place to report problems directly to Thunderbird?

Thanks for any help.

I have been using Thunderbird for a very long time. Today is the first time I have seen this happen.

In the column on my left side that has my account and folders for those accounts it is showing 5 in my junk account. But in the preview window to the right of that column there is nothing showing as far as any entries as junk mail. It is completely blank. What do I need to do to clear this 5 from the left column Junk folder??

I have tried resetting the machine and that did not work. I even went into the webmail site for my email provider and there is no junk email showing there at all so as far as my email provider goes, it looks like everything is working there.

I am trying to add an email address to thunderbird it is an outlook email address [edited]@outlook.com I have checked the address and the password and both are correct however thunderbird says that the configuration is incorrect and will not accept it. also I have it open in another browser window will that cause problems ?

All of a sudden today I'm getting the message "could not connect to server mail.twc.com; the connection was refused." So, I'm unable to send/receive email. I called Spectrum and they said go to Spectrum.net. Yes, I was able to get my email that way, but that eliminates the ease of using Thunderbird. I've read all the messages about this issue, including changing various settings, but none have helped. Spectrum says nothing has changed on their end and it must be a Thunderbird issue. My current settings are: Incoming: Server Type: POP Mail Server Server Name: mail.twc.com Port: 110 User Name: [my email address] Connection security: None Authentication method: Password, transmitted insecurely

Any other suggestions?

I'm using TB 150.0.2 on a Mac with the latest update of MacOS.

I just deleted all of my archived emails, thinking it was stuff that I had sent to trash. I.e. I deleted all archives, then emptied trash. Only after I did that did I realize that I had deleted things I want to save.

I'm pretty sure there's no way to undo emptying the trash, but I use Time Machine to back up. If I open time machine and go to the most recent back-up, I should be able to get everything back, right?

What folder (or folders) should I restore from a Time Machine back-up?

I have created an account instance in account settings, and the "Test connection to server" says it is OK, but when I go to the mail tab the get messages button and New Message are grayed out an NO accounts are listed in the "folders" area. Not does it ever ask for my password to the SMTP server I have selected. I have an existing account with my own email service (Hover), and MUST connect to that. This is critical, as I need my e-mail to accomplish necessary activities.

Thunderbird administers my 7 "aol" email addresses (accounts) on my Dell laptop (running Windows 7). 5 of the accounts are behaving normally, but the other two accounts appear to be linked. So, when I send an email from one of them, it appears in both "sent" folders. When I receive an email in one of them, it appears in both "in box" folders. When I visit "mail.aol.com", these 2 accounts behave normally. So it appears that they are linked within Thunderbird. Can you suggest a possible solution? Thanks, Tim

I'm currently running Thunderbird 140.9.1esr and it shows an update available to version 140.10.0esr. However, when I click on the update button, it shows "downloading" but it stays at 0 bytes and will not download the update. All previous updates to my current version automatically downloaded and installed after I clicked on the update button. How do I fix this or is there a problem with 140.10.0esr? Thank you!

I can receive outlook e-mail but I cannot send from Thunderbird. I am asked for a password for the specific Microsoft server. I enter my Microsoft account password but this does not work. Security setting is STARTTLS withNormal Password authentification. My other Thunderbird non-MS e-mails are problem free.

Version 140.10.2esr | Released May 8, 2026 I get this message every time: Sending of the message failed. The message could not be sent because connecting to Outgoing server (SMTP) mail.twc.com failed. The server may be unavailable or is refusing SMTP connections. Please verify that your Outgoing server (SMTP) settings are correct and try again.

Thank you, George Correia
