I have been using Thunderbird for many years. I have 4 accounts that have all been set up and working fine. This morning the 2 yahoo.com accounts stopped working. I logged in to the impacted accounts using a web browser and password just fine. I then updated Thunderbird to 116.0 to see if that would fix the problem, but it did not. The outlook and gmail accounts are working fine, for now.

When Thunderbird attempts to download mail for the yahoo accounts, I get a large pop-up window with "Edge: Too Many Requests". The pop-up window is blank except for that error message. I get the small pop-up with the Authentication Failure message. Sometimes I get Retry, Enter Password or Cancel. But I never see a window that will allow me to enter my password.

I can send/receive mail from the accounts while logged in via a browser but authentication fails within Thunderbird.

Thunderbird just updated to 144.0.1 (64-bit), and now I see a blank area where message list used to be. This true for all accounts and all folders.

I used to see this issue temporarily after compacting folders, but usually (but not always) went away and messages showed up. Sometimes I had to close and restart TB. Now even that wont bring up the lists. I'm dead in the water. And, yes, I did reboot my computer as well. Screenshot of this state attached.

Thanks for any help--it's urgent. Bert

Hi,

I'm trying to add another account to my Thunderbird client (already have 2, a IMAP account, and a Hotmail/Live/Outlook), but i keep getting the error "Exchange auth error" and no possible way to manually configure the server or anything, despite the mail server not being an exchange server. Following this, it just freezes the view, although i can close the popup by pressing escape.

is this a bug in the most current version of Thunderbird, or am i doing something wrong?

今日Thunderbirdのメーラーを開いたらメールフォルダが英字表記に変わっていました。 具体的には「受信トレイ」は日本語のままなのですが、「送信トレイ」が「Sent」になり「迷惑メール」が「Junk」に変わるといった感じです。 受信トレイ以外はすべて英字表記になっています。 設定にある「言語とフォント」は「日本語」のままで変更はありません。 元に戻す方法をご存じの方がいましたら、ご教示をお願いいたします。

Did ask forum for help on 12/9/2025, and though there was some info on line to solve my problem, I was unable to understand it, or proposed solutions did not work.Tried now to log into mozilla account, but cannot find any section about any replies. As problem driving me crazy, will try again.

1 When emails come in, instead of the sender being shown in the from box, it gves me at pethen.riseup.net as the sender. 2 If i click on any link in the text of the email which I need to access, this function does not work. All that appears is the link text I click on gets surrounded by a text edit box (ie a thin square line with small boxes you can put an arrow on to change shape of box for editing 3 a yellow banner appears at the base of any email reading " a unique identity matching the from address was not found. + "the messagewill be sent using the current from field and settings from identity peter hendry<pethen@riseup.net> 4 My other emailaddress linked to my mozilla thunderbird client has no problems. This has to be such a simple problem relating to the account set up which for some reason my PC has taken into itself to change, either text in my address books do not match, or I have ticked a wrong bos in the setup, or not ticked one at all,

Please can any help this struggling man! Peter

There is ONE SPECIFIC email message in my inbox that I cannot move, copy or delete. Whether I drag-and-drop or use drop down menu - same result. This is the ONLY message in all my email accounts/inboxes which has this problem.

Continuing the attempt to move or copy causes the drop down menu to ask me if I want to move/copy the message AGAIN - but it still does not move or get copied. Hitting "Delete" on my keyboard or clicking the "garbage can" icon in the drop down menu has no effect - the email remains in my inbox.

I am using Tbird 140.1.0esr (64-bit)

When I open Thunderbird, I now get a message window asking for a User Name and password for both Caldav and Carddav.

I did not change anything in my setup and they started to appear.

Can anyone tell me how to stop these pop-ups from appearing ?

Screenshots are attached.

Thanks, David.

Recently I have noticed that the toolbars I use frequently are hidden. I have searched help for a solution to the problem - I want the toolbars to be always there, not just sometimes - and the advice to fix the problem is old and does not work. Is there a solution to my problem, or do I just have to always toggle "alt" to get a toolbar when I need it?

Thanks for any help!

So there was a problem with AOL today and I'm using Thunderbird for my Verizon account now AOL is back up and running but on my computer Thunderbird will not let me log in to The Host keep saying it's failing?

My windows 11 computer stopped accessing yahoo mail. I get message

Unable to write the email to the mailbox. Make sure the file system allows you write privileges, and you have enough disk space to copy the mailbox.

I have tons of space.

The automatic setup fails to find the settings when creating a new mail account.

Manually setting up the account settings returns an error that Thunderbird can't find the server. The system has no issues finding the server. Calendar in Thunderbird has no issues finding the server but when trying to setup an email account I get the error that it can't find the server.

Pressing continue creates the settings but fails to create a username and password for the account.

There is now way to create a username and password for the account so it fails to connect to the server.

There is no way to create an account by providing all the information. We don't need a nanny, we need something that works.

Why did we mess with something that worked? How do I add an account manually?

Hi all.

Previously, when moving to a new computer (Windows 11) with Thunderbird, I would install a new instance of Thunderbird on the new computer and run it once. This created the default Thunderbird profile in the Profiles directory. I would then copy the contents of the existing Thunderbird profile into the new one. This allowed Thunderbird to be fully operational with all accounts and filters working, requiring no further setup.

In version 140, I have followed the same process. While I do see all of the email accounts, they are not functioning.

Any advice on how to do a migration with Thunderbird 140 version?

I downloaded Thunderbird hoping to replace Office365 Outlook (classic). Installation went fine but when I attempt to download email from "mail.twc.com" nothing happens. No error message(s). When I tried to send a test message to a different email account did receive error:

"Sending of the message failed.

The message could not be sent because the connection to Outgoing server (SMTP) mail.twc.com timed out.    
Try again."

I have double checked all of the TWC server settings and all settings are as specified by Spectrum:

SSL: on Protocol: POP Port: 993 Require Authentication: YES (using account pwd) In-bound & Out-bound servers: mail.twc.com SMTP settings same as POP except: Port: 587

Transfer Thunderbird email and data to another computer. I have attempted to transfer my email data from / to Windows 10 computers. The instructions seem straightforward but so far I have not been able to bring up the "new" computer after copying / transferring the data. I have a Linux laptop I could transfer to, but the versions don't match and I'm not sure it would work anyway. Any help or direction to instructions (I thought I have looked everywhere) would be great. Thanks

I went to use Thunderbird mail on my laptop for the first time in ages. I can receive emails but they won't send:

Log in to server SMTP-mail.outlook.com with username x failed Retry - Enter New Password - Cancel

- I entered the current password, which works fine for Thunderbird Mail on my desktop PC, and checked the box use password manager.

Send Message Error: Sending of the message failed. Unable to authenticate to Outgoing server (SMTP) smtp-mail.outlook.com Please check the password and verify the 'Authentication method' in Account Settings | Outgoing server (SMTP)

Server Type: IMAP Mail Server Server Name: imap-mail.outlook.com I CHANGED THIS to outlook.office365.com - to match the server settings on Thunderbird Mail for my desktop PC - and restarted Thunderbird, but the Log in to server failed message displayed again. Port: 993 Default: 993 Connection security: SSL/TLS Authentication method: OAuth2

I trust I have provided sufficient information for you help me. Thank you!

I am able to receive emails on Thunderbird but I am not able to send emails to anybody from Thunderbird. That happens on two computers I have. I am able to send emails from Outlook. Therefore, it is not my email provider's (BluePeak) problem. When I try to send an email from Thunderbird, I receive the following error message: “Sending the message failed. SSL received a record with an incorrect Message Authorization Code. The configuration related to must be corrected.”

Please help me resolve this issue. Thank you very much!
