Thunderbird stuck on "sending message" Tried troubleshooting mode - no effect. Can use Gmail via browser with same settings Re-started Windows (7), cleared Thunderbird cache - still stuck. No SMPT settings changed Problem only started yesterday

Having just re-installed Thunderbird I receive the following error message when trying to set up my gmail account, which had been working fine before

400. 

That’s an error.

The server cannot process the request because it is malformed. It should not be retried. That’s all we know.

The password is correct as I can login from my browser and I have easily setup my other email accounts - not gmail. Also have re-started PC and Thunderbird.

Help please, regards, Haydn

When setting up for authorization in sending email from Windows Live account, the Oauth2 option (as seen in the guide) is not available to select ? See Picture

Hi,

since I installed Ubuntu 24.04 Thunderbird (V. 128.1.0 as snap app) changes the path of the local directory each time I restart Thunderbird. My original path to the local directory points to a mounted drive e.g. /media/username/disk... Thunderbird changes it to /run/usr/1000/doc/.... How can I avoid this? The same thing happens also to the path of the signature file.

Thank you for your help! Ubuntu

Hello,

I can't receive new emails on my Thunderbird account because every time I try to refresh my inbox, I get this message:

‘An error has occurred while saving your messages. Make sure that the file system gives you write rights and that you have enough free disk space to copy the inbox’.

No problem with webmail.

We have another computer in the office connected to Thunderbird that receives all our emails. All the settings are the same, except that we haven't updated Thundebird.

We use a POP system.

Thank you for your feedback!

Message filters not working after transfer to new windows device. (Apologies for long report below). Problem is similar to that reported and still unsolved here: https://support.mozilla.org/en-US/questions/1391209

All old messages automatically accessed under IMAP protocol sit within correct email folder on new device.

Message filters rules successfully located on old device, copied and placed in corresponding windows folder on new device. Email folder structure looks identical on both devices.

New messages sit in inbox on new device, without being filtered. Instead error messages appear, repeatedly.

"The folder 'xxxx' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

The folder 'yyyy' could not be found, so filter(s) associated with this folder will be disabled. Verify that the folder exists, and that filters point to a valid destination folder.

If same new messages are accessed on old device, they later appear in correct folder on new device, and no longer sit in inbox

How to make email folder structure on new device visible to filter rules there ? This is necessary for filtered email to work successfully on new device, without requiring old device to be operational - it will be taken out of service in near future.

Hi Everyone,

I have Thunderbird installed on two computers. When I receive messages that are in plain text, on one computer they are being displayed in a modified format with whitespace and carriage returns removed. On the second computer the messages are not being reformatted.

What setting do I need to change so that plain text messages are not automatically reformatted?

The trouble is that these messages are written with the contents displayed out in a nice table format, and when they are reformatted it makes them very hard to read.

I have tried searching for the answer myself, but I haven't been able to find anything that directly relates to this question.

Thanks, Ian

We've got around 2000 AD-joined windows 10 boxes, with TB as the mail client, for years. Users are connected as domain users (ie, non-admins). Now IIRC, first TB version installed was 60. TB was updated throughout the years automaticall without a hitch, up to and including version 115.x.

With the advent of 128 we had started receiving calls from users stating that a message pops-up asking for credentials. Taking a closer look we discovered that each and every installation needed admin credentials to be able to do the upgrade to 128.

Is this a bug or normal behaviour? It is definitely a problem, especially for small organizations that do not know how to install manually an MSI of the latest version.

I have Nebula 128.2.0esr (64-bit) for Windows 10.

On the same day of my last Thunderbird update, a mysterious folder appeared in the root of my C-drive with Chinese (?) characters.

The Folder name is: u馐㕈ʶ

(See the screenshots below.)

Inside the folder appears two items:

A Subfolder called: IDB and a file called: .metadata-v2

Inside the IDB Folder, I see these things:

Folder: 3647222921wleabcEoxlt-eengsairo.files and these files: 3647222921wleabcEoxlt-eengsairo.sqlite 3647222921wleabcEoxlt-eengsairo.sqlite-shm 3647222921wleabcEoxlt-eengsairo.sqlite-wal

Inside this folder: 3647222921wleabcEoxlt-eengsairo.files I see:

a folder called: journals and a file named 21 and 22

Inside the journals folder is empty.

Does anyone have ANY idea what this Chinese Character folder is?

Googling it, I see that it could have something to do with Firefox, but I don't use Firefox much and this folder appeared on the same day my Thunderbird updated.

Trendmicro Housecall, Windows Defender, HP Wolf Security -- NONE of them flagged these as suspicious, but I just don't like this mysterious folder on my C-Drive and wonder where it came from and what function it serves.

Thank you!

Hi, I use Thunderbird as an email client from Office 365. Thunderbird requires OWL to work with 365 and it is installed and working.

I have an email account associated with my website. "Sales@" Thunderbird filters the message on arrival and sends it to "Paul@" When receiving into "Paul@" the body of the email is blank. (only certain emails. not all). This has only just begun in the past 2 weeks. Because the message is moved in Thunderbird, there isn't a copy of it in 365.

Please see Attached image of errors from Ctrl+Shift+J.

Thanks, Paul.

I moved several messages to a folder called "Teamskeet", but when I opened that folder it didn't display any messages.*** Through tiral-and-error I discovered that the "Toggle message threads" option would show me the messages in that folder.

  The upoaded image display is annotated to explain my question better. Specifically, are the messages that are displayed ONLY the ones in that folder that are threaded? And what does it mean that 15 messages are selected. I didn't knowingly select any  messages.

*** Initially, it didn't show any messages, but after I closed and re-opened TB it did show the messages in that folder. I'll be doing some troubleshooting to re-create that scenario.

Thanks for your help, SweetTasha

I have used Thunderbird for quite a while so finally sent a donation. Withing a few months, my emails won't send. Sometimes they won't receive either. I went to Comcast and asked for help and they gave me a new password for one email address and it worked for a few days now NOTHING. I'm so frustrated! I don't believe it has anything to do with Thunderbird but since Comcast is no help, I'm desperate. I have 4 email addresses and each is important to have access to. Please help me.

I have used Thunderbird as my preferred mail client for many years. Recent upgrade to Kubuntu 24.04 from 22.04.4 seems to have changed storage options. Thunderbird 128.1.0esr(64bit)

I store my mail on my local server so that I can access it from a number of different computers on the same network. If I set the Local Directory to that network folder it is changed to /run/user/1000/doc/5f5f8977/mail.xxxxxx.com and the mail is imported to my local disk in that folder.

However, when I restart the computer I have to set up the network folder again each time.

I have never had this problem before. How do I set the Local Directory permanently to the network server address? Thanks Bob

I can receive emails but cannot send them I get a message that says the outgoing server (SMTP) hacksaw-mail.internode.on.net failed Please check your Outgoing server SMTP settings Could you please assist in providing the correct settings so I can check Thankyou Warwick Hack

I recently installed Thunderbird on a new installation of Ubuntu 24.04 using the "Installing Thunderbird manually" instructions. Everything works fine except that Thunderbird doesn't want to use the Thunderbird icon in the dock. Thunderbird opens and runs fine when I click on the Thunderbird icon, but it then puts a new default icon on the dock that looks like a gear instead of just "using" the Thunderbird icon to indicate that the application is running. I've attached a screenshot. When I close Thunderbird, the gear icon disappears.

When importing my contacts from my android phone (Samsung with Android 14) as a .vcf file, Thunderbird import the file but only shows the contacts from 1 group ( I have organized my contacts in my phone by groups, Business, Family, Friends, etc), the rest are shown as dots icons with no data in it, in this case, all my Business make it to Thunderbird but the other groups are ignored. I have also added this .vcf file to My Contacts in Windows and they can be accessed in and individual or list format in the File Explorer. Thunderbird should be able to read this folder with no need for imports. Appreciate any comments in this matter.

i tried system restore. didnt work. tried reinstall didnt work. this happened several months ago and the only was to fix it was using my backup drive. what is causing this???

Greetings. Long-time Thunderbird user on PC and before now trying to load onto 2024 Macbook pro. Configuration identical to that on PC and have checked with person running with same configuration on mac. When tried to initially configure Thunderbird reported could not find email settings though email and password were correct, so configured manually.

Now trying to send mail get "login to account "smtp.gmail.com" failed. No way to bypass and do not know how to fix. Outgoing sever is SMTP and is configured correctly using OAUTH2.

Tried running in troubleshoot mode but no difference. Also not receiving any email.

thanks much for any tips jp
