i can not receive mails, since the update to 128.5.2ESR not on imap.strato.com not on imap.gmail.com not on mail.yourhosting.com

just since today after the update. sending emails seems to work.

I did NOT change anything in the accounts.

How to solve????

Thank you.

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。

I made a mistake. I had 128 and went up to 140. It pretty much looks the same, but a big difference is an extension I always use says it will not work with 140. I don't care how good 140 might be; if I can't use my app, QUICKTEXT, then I don't need this. How do I go back to 128 or to a version that works with my extension?

Good morning. I need help with sending emails in Thunderbird. The problem has existed for a couple of days now and is confusing as some emails are sent and others fail. I am receiving mail OK. Details of my setup are :- I am using a HP All-in-one desktop running Windows 11 with Norton 360. My Thunderbird account settings: Server type: IMAP mail server User name: ****@gmail.com Server name: imap.gmail.com Port: 993 Connection Security: SSL/TLS Authentication: OAuth2 Outgoing Server (SMTP): Google Mail – smtp.gmail.com (Default) User name: ****@gmail.com Port: 465 Connection Security: SSL/TLS Authentication: OAuth2

The problem: I only recently set up Thunderbird and at first it seemed to working OK. However, now when I try to send a message, after some time, I the following error message :-

"Send Error Message Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) smtp.gmail.com timed out. Try again."

What is particularly confusing is that some messages are being sent. I have tried several fixes that I found from the Mozilla, Google and Norton web sites but none of the fixes resolved the issue. Any assistance would be very much appreciated.

Regards Mike

PS: I have 2 email accounts set up in Thunderbird. I just tried sending a test message from the Gmail account to the Bigpond account. From the Gmail account it appears to have been sent but in the Bigpond account an error message appeared as follows :-

"Could not connect to the mail server smtp.telstra.com; the connection was refused."

I don't know if this is a related issue or I have another one to resolve.

I have a brand new install of Thunderbird, and I want to import .mbox files that I converted from Outlook .pst files.

I have seen many support articles saying that to import .mbox files, I need to use the "Local Folders" option in the Folders menu on the left hand side of the main page. I have added the ImportExportTools NG plug-in, but I don't see a "Local Folders" option on my main page.

I must be missing a step. I have attached a screen shot.

Thank you for your help.

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?

My local folders are missing. There is nothing in my profiles to recover from. This is the second time this has happened after a Thunderbird update. Last time the local folder were found in my profile and I was able to restore them, This time there is nothing to restore. Has this happened to other users?

From the article "Microsoft OAuth Authentication and Thunderbird in 2024" there is a screenshot showing a OAuth2 option for the SMTP server setting with STARTTLS connection security. It does not appear for me. There are only the five options, as shown in the screenshot. How do enable the option to be available in the drop-down list or set it?

The available options are:

No Authentication Normal Password Encrypted Password Kerberos / GSSAPI NTLM

I am on Thunderbird version 115.12.1 (64-bit), Windows 11, version 23H2, build 22631.3737

I am having trouble manually configuring an AOL email account (username@verizon.net). AOL's instructions say to manually configure the account. I tried to do that twice, once with IMAP and the other with POP.

Now, I have two email folders in Thunderbird that I cannot use. They are both empty because I get a message box that says "Login to server imap.aol.com with username@verizon.net failed." when I try to use them. When I use the same login credentials to login to the website mail.aol.com, they work.

I have to contact AOL as to why when I try to access the account with an email client (Thunderbird and Outlook) I'm getting password errors. In the meantime, how do I delete the two email folders created incorrectly in Thunderbird?

Thanks for your help.

Thunderbird ver 140.0 (64-bit) on Windows 11.

Brand new, fresh installation of Thunderbird. - Added a GMail account. That worked. - I tried to add an account with my personal domain. I enter my name, the email account, and Thunderbird gets stuck in an unending loop looking up the configuration. - Other email clients have successfully looked up the config and did the setup without a problem. - The email account is handled via IONOS.com servers. - If you gave me a manual setup option I could handle it but there is none; TB goes straight into trying to handle it itself.

Any ideas?

TY, Frank

I'm using thunderbird for gmail account, and I struggle to mark some events notification as completed when they are deleted using gmail interface. They keep on poping up but when I hit `Dismiss` it gives me this error: ``` Status Code: 2147500037, The request cannot be processed.

Server Replied with 400 If you're seeing this message after snoozing or dismissing a reminder and this is for a calendar you do not want to add or edit events for, you can mark this calendar as read-only to avoid such experience in future. To do so, get to the calendar properties by right-clicking on this calendar in the list in the calendar or task view. ```

I don't want to make my calendar read-only because I'm still gonna use it but I can't remove these annoying pop-ups because of the error. Please help what can I do

My name is graeme , my wife Olivia.

I have many many messages from various people; if I reply to a a mail from "fred", Thunderbird creates a mail:

to: fred@xxxx from: graeme@xxxx

I have several messages from my wife , that behave in this same fashion (ie , as you would expect) but ONE message, when I reply the message displayed in Thunderbird (ie NOT YET SENT, so no SMTP etc yet involved) says:

(it does NOT have a REPLY-TO header BTW)

to: graeme@... from olivia@.....

...I've search back though my mailbox and all the mails from my wife work as you would expect, bar this one ...AND ONE OTHER that I found:

This says:

from olivia@.xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

When I hit reply , it generates a message:

from olivia@xxxx to: company@xxxx, olivia@xxxx. graeme@xxxxx

So the from and to in the reply are exactly the same as the from/to in the initial message (they are not swapped)

So, to be clear 99% of messages are fine, it's just one or two cases where I get this odd behavior.

I have an IMAP email account with Virgin Media. I have been backing up my Thunderbird email as follows (not sure where I found this method) WIN + R %appdata%/Thunderbird/ Ctrl A Drag all files to External Hard Drive When I open the Backup file there are two files Open 62hcjzp7.default-release (whatever that all means) there are loads of folders one being MAIL Thus contains all my folders from Local folders For every one there is a File and an MSF File How do/Can I restore these to my current version of Thunderbird? I have tried Import from another Thunderbird installation, Profile folder Open the back upp and Select Profiles Tick Mail messages. It says Compete but never copied anything It does create an empty folder under Local Folders in Thunderbird.

My question is can I restore from this backup? If not, what is the best way to backup and restore Thunderbird? Bill

I'm trying to move Thunderbird to a new PC. Both PC's are running Windows 11. I've followed the instructions for locating my profile. According to "Troubleshooting Information" my profile is supposed to be located at "C:\Users\photo\AppData\Roaming\Thunderbird\Profiles\k6i7koof.default-release\Mail\Local Folders". When I click on the "Open Folder" button, I receive an error message that the folder does not exist. When I try navigating to the folder manually, I can not find a "Thunderbird" folder under "AppData\Roaming". I've selected "Show Hidden Files/Folders" under Windows Explorer. I know my profile exists because I can access a set of Local Folders when I'm in Thunderbird. I'd really like to move those folders over to my new PC. Any help to find the profile folder will be much appreciated.

Hello, I'm using the most recent version of Thunderbird on a desktop using Windows 11. Just this morning (Aug 11), all incoming email to all my four accounts are coming in with no subject or correspondents showing and when opened the email is not formatted in HTML, just plain text and lots of code. I have tried several fixes with no success: repair folders, turn off all add-ons and anti-virus protection, uninstalled and reinstalled software. Can you help, please? Thanks!

I have several mail accounts connected to my thunderbird Version 115.10.1.

One of them is a account that regularly notifies me if about updates on my homepage. I want to receive those emails, but I don't want a notification about them. I do however want to receive notifications about emails from other accounts.

How can I disable the notifications for only one account?

Best, Alex

On January 21st 2025 I changed my Spectrum account password. Almost immediately Thunderbird could not log into the spectrum maintained "mail.twc.com" server. When I called Spectrum support I was told the old Spectrum use of separate passwords for SMTP and IMAP was changed to use the same password as the spectrum web page which is now the same for all spectrum logins, a "one password to rule them all" scheme in November 2024. I changed the passwords in Thunderbird for IMAP and SMTP, but it still will not connect. If I do an auto populate attempt, the server actually responds with the correct setting so I know I am reaching the server. After five days trying to resolve the issue with Spectrum I was told this is a know issue with Thunderbird and it is not the server but the third party application. It is bad enough they reconfigure things like this without disclosing it. It baffles me that the changes they claim were made in November 2024 only make themselves known when the service stops working nearly three months after the change and only when I changed the web site password. Anyone know how to solve this? Thank you so much in advance.

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.

July 2024 - Thunderbird is demanding that I change my Hotmail password, after long trouble -free operation. It will not login. Why? (I have not changed the PW yet, hoping for a solution that will avoid the necessity.) I fear that it may be due to some fault in OAuth. Can anyone please provide any help to overcome this problem? Tom.
