I'm having trouble with Thunderbird on my new Windows11 laptop. I've used Thunderbird for years and years on the old Windows10 one, but can't get it to work right on the new one. The version info it gives is "128.4.4esr (64-bit)"

Specifically two problems. (1) Every time it starts it asks for my yahoo server's password. Even though I check the box asking it to remember it, it doesn't. Under Settings->Privacy&Security (under Passwords)->SavedPasswords, the list is empty. (2) Second problem (may be same as first, but in a different form) Whenever I try to send an email message, it fails. It waits a long long time and then gives a popup saying "Login to server smtp.mail.yahoo.com with username bill.marshall@verizon.net failed." It gives me an option to enter a new password, and if I click there it doesn't let me enter the password again, just re-tries, again waits a long long time, then gives the same error popup. When I cancel, it gives a new popup saying to check the password and verify the 'Authentication method' in Account Settings (which I have done, and all looks OK).

Thanks Bill Marshall, bill.marshall@verizon.net

Hi, I download some e-mails. After checking the emails, I want all of them to be deleted from thunderbird but... ...I want only specified emails deleted from server.

In Mac's "Mail" program, there was a special window, where I could see all e-mails on server and just select which I want to remove from server.

In old Outlook, I've used "Rules". There I could set the parameters for specified e-mails and then tell outlook to "leave that message on server" or "Don't download that message from server".

How to do it in Thunderbird?

Hi, I accidently set the email size in the Config editor layout.css.devPixelsPerPix to 125 (instead of 1.25), which results in the program no longer being able to be viewed as it takes up the entire screen.

How can I undo this please, since the reset option is not viewable due to the immense size now.

The tutorial video I followed is this: https://www.youtube.com/watch?v=klIOX4dsXU4

I appreciate your knowledge, please in simple steps :-)

Thank you, Jana

Running 115.16.3 because I have a Windows 7 Pro computer. Fine for years! Then a series of power failures and system crashes.

Now Thunderbird looks very plain - black and white lines, no 3D blue colors, Delete button is text only, it used to be red. Entire interface looks simple and old.

Checked my outgoing and incoming server settings. They match the settings in Edison+ Email that I use on my phone. Phone is getting new messages, Thunderbird on my desktop is not.

Outgoing mail asks for a password each time, which it did not before. I know the password, but what a pain.

I have hundreds, actually thousands of emails saved in local folders. They are all there, but I am worried if I can migrate them if I move it to a different computer.

My inbox has nearly 300 messages now, and growing rapidly.

HELP!

If there is one thing I have always disliked is 'email migrations. When deciding to switch from Thunderbird to Outlook for the MBOX data of 2024-25, I was expecting to face a really annoying and long process. But surprisingly, it wasn’t. Here’s what happened.

I began by defining tools that would help in the transition to be smooth. Out of trying many options, I found the WebbyAcad MBOX converter software. It appeared to be reviewed and featured well, so I said let me try it.

The general preparation was very simple. The tool was downloaded, and I imported the MBOX files and then chose PST as the file type to save my results. The best part? It was having the ability to batch convert something, which would have taken me hours to do.

As soon as I clicked on “Convert,” I could hardly believe how fast a work of it was. That is an undeniable advantage – every mail, folder, and even attachment was intact. I did not even delete a single file, which was way faster than I anticipated.

That which I had probably estimated to take days, was actually achieved in minutes. These new PST files are quite compatible with Outlook 2024 and I had no problem at all trying to access all my data.

If you find yourself in a similar situation, there is a solution; email migrations don’t have to be a headache. There shouldn’t be any hitches if you get the right tool. In doing what I thought was an impossible mission after research, the WebbyAcad MBOX email migrator made it easy as pie.

Hello, I am planning to do a fresh Linux install and in this context I also want to setup Thunderbird completely new, starting with the default settings. However, there are two things I would like to backup and restore (export and import).

1. The information which emails I have explicitly labelled as "Junk"/"No junk"
2. The information from which domains I allow loading remote content

I think this makes a lot of sense because I can setup my accounts easily and the mails, addresses and calendars will be synced from the cloud, and view configuration is no big deal either. Only that kind of "user data" that was gathered over several years is something I want to hold on to, and be able to continue to use. Is this possible somehow? I am not afraid, e.g., to manually copy individual files from the profile folder, if that data is stored cleanly separated somewhere. Kind regards, Chris

Since moving to Windows 11 and reinstalling Thunderbird, I cannot access emails by this route. I have a domain hosted by Easily and can get to my emails directly through their Control Panel, but using the same email, password, ports etc through TB it fails to find the account. I have rechecked all the settings with Easily and tried several times entering them manually in TB, with the same result. What else can I do?

For some reason, I was obliged to change the password on one of my external email box. I made a mistake creating a new mail box in Thunderbird with the same name and the new password, instead of just informing the new password on the existing mail box. I have now two mailboxes with the same name in Thunderbird. One is enough, but I can't find the way to remove / cancel the second one...

Thank you for your help

I've found that some of my emaIls in very latest Thunderbird mail client on Windows 10 have had their content replaced with a phishing email - the title of the email is as per the existing email received yesterday but the content is a phishing email made to look like a contact request from a motor insurance provider that I used years ago and the email is addressed to the email address I used when dealing with said insurance company.  It's only an issue with Thunderbird as the email looks fine on my mobile phone and in Outlook.  Either Thunderbird itself is compromised or one of the installed extensions is compromised.

Has anyone come across a similar issue?

I'm running an antivirus scan but I think I might uninstall and wipe clean Thunderbird if the scan shows no issues.

Hi I've just realised that Thunderbird has been deleting inbox messages from server with IMAP server setting. Is there any way how to turn this off? I would expect this to happen with POP but not with IMAP. Cheers Mike

Dear,

I have a problem with sending emails via Thunderbird desktop platform. Namely, I have set up a Yahoo account, and set the SMTP authentication method to OAuth2, however I still have the issue with sending emails. There's no problem with receiving emails.

Can you help me please?

Hi

I have several different email accounts. All but one are working fine. But my primary account is continuously unresponsive and freezes. This has been going on for several weeks now and today I can't get that account to work at all.

I'm on Windows 11 and have tried re-starting my laptop in Safe Mode but the freezing persists. I've tried turning off Windows Defender - it makes no difference and I don't have any other anti-virus running.

I have 450 emails in my Inbox and don't want to lose any of them or my address book. I do back up each week.

Not very tech savvy and no clue how to sort the issue out.

All help appreciated.

Hi all,

I just set up an email account with POP3 at Thunderbird and enabled leaving messages on the server for, say, 30 days. But if I enable this, all messages stay on the server. I have tried this using my Gmail account, Office365 account, and another provider's email account, but the result is still the same. Do you have any suggestions for this case? Or am I missing any setting?

The reason I need this feature is because I use an email provider with a 2 GB email space limit. I want only the past 30 days of messages that are still on the server to avoid email space being full, meanwhile 30 days at the server to allow user still able to read the past 30 days of email from their mobile phone or web.

My first support request about this was posted on Mon, Nov 18 (8:53 a.m.). I never got a response--probably my fault for posting a minor correction which may have caused everyone else to think someone knowledgeable had responded. I apologize for starting a new thread, but it’s been almost a week now and I really need help. The situation: I get my email via POP, and something got corrupted as a result of doing a backup of TB on Nov 15 using MozBackup. Following advice by Toad-Hall on 11/7/23 to a similar support request, in Troubleshooting Information, inside Profile folder, then in Mail, then in the folder for my server, I renamed “Inbox” as “OldInbox.” A new Inbox and new Inbox.msf got created in Mail > 'my-server.' The new Inbox is 0 KB and is dated to the Nov 14, the evening before I did the MozBackup. The date on the new Inbox.msf keeps advancing. There’s a OldInbox.msf file too, with date that keeps advancing. The new Inbox.msf file doesn’t work or isn’t getting used or some such. When I open TB, Inbox still shows the same old list of emails (now inaccessible) that used to be there and that are now accessible in the folder OldInbox. I still get the error message when I try to Get Messages. TB is still not downloading emails from the mail server. How do I get a functioning Inbox?

Hallo Up the 4th of October all was ok (see Pix 32), after the 4th I cannot send emails. Error message is Pix 36. Output settings Pix33. Input settings Pix 34. Thunderbird version Pix 40. Zonealarm Pro Version Pix (41).I have a newist laptop with windows 10

Laptop I have a newish laptop with windows 10 (fully updated) and with the latest versions of Thunderbird plus Zonealarm. This laptop can recieve but not send as well.

I've turned off Zonalarm on both and tested to no avail.

Cheers

I read on the internet that if I go to Mail then the body of the email should be available when blank in above subject files/folders. This does work, but it has only just started happening. Internet information says due to out of date apps, does this mean Thunderbird is out of date and needs updating because usually the updates are automatic? Or does Thunderbird need to look at the problem and fix, I shouldn't have to go to Mail each time an email body is blank. Not all emails are blank. Appreciate your assistance.

Can this be doctored to send via Thunderbird? If so pointers would be apreciated! Sub FredWeeklyReport() Dim OutApp As Object

   Dim OutMail As Object
   Dim MyAddress As String
   Dim MyAddress2 As String
   Dim Response
   Set OutApp = CreateObject("Outlook.Application")
   Set OutMail = OutApp.CreateItem(0)

   On Error Resume Next
   
   Response = MsgBox("Fred. Hide all invoices, check worksheet is up to date", vbOKCancel)
   If Response = vbCancel Then GoTo ExitLable
   'Worksheets("Sheet19").Visible = False
   MyAddress = Sheets("Work summary").Range("Eddress1").Value
   MyAddress2 = Sheets("Work summary").Range("Eddress2").Value

   With OutMail
       .To = MyAddress
       '.CC = MyAddress2
       .BCC = ""
       .Subject = "Fred - PM - Weekly report"
       .Body = "Attached please find my weekly report. Regards, Peter"
       .Attachments.Add ActiveWorkbook.FullName
       'You can add other files also like this
       '.Attachments.Add ("C:\test.txt")
       .Send   'or use .Display
   End With
   On Error GoTo 0

ExitLable:

   Set OutMail = Nothing
   Set OutApp = Nothing

End Sub
