Fórum da Comunidade de Thunderbird

Email from a trusted address over past decade is suddenly going to Junk as of today. Cannot see how to whitelist the Sender, and googling the question tells me to go to Tools>Options, however Options does not show in the Tools menu.

Since yesterday I am unable to receive mail. When I send a test email the message below comes up. Your message was sent but a copy was not placed in your sent folder (Sent) due to network or file access errors. You can retry or save the message locally to Local Folders/Sent...

I have searched, read and tried all fixes on this topic already provided but nothing has worked.

Thanks in advance.

I composed an outgoing email message that I wanted to keep for future use, and saved it as a Template. That not only saved it under the unified Templates heading, but created a second appearance of my main email account with its own Templates subfolder. At that point I decided I really didn't want to keep it after all, so I deleted the message, but the second Templates folder didn't disappear; its still on the tree list as an empty folder. Right-clicking that folder doesn't have a Delete function, but it does present a Repair option, but running that doesn't help. How do I get rid of that unneeded individual email account listing and the empty Templates folder?

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 searching for a solution for my problem and maybe this is a possible new feature that would help many users. When I open my thunderbird, all attachements open in a new tab, easy and very usefull because of the invoices i need to pay are always open, and when paid i save+ close them. But then i have to send the invoice attachement to my accountant. So i have to go to the original mail AGAIN forward this mail to the accountant etc.....It would be easy if there was a little button in the open attachement tab that directly opens a new sendmail tab with the open attachement already included in the concept.....Maybe i didn't searched very well....BTW I love thunderbird and install it @ all my customers sites instead of MSOutlook, plugins are fine an email reading is once set up correctly the most easy to read interface. the attachement tab is displaying an url like : imap://my%40mail%2Ecom@imap.mailserver.com:993/fetch%3EUID%3E.INBOX.xxxx%3E128?part=1.2&filename=20210446.pdf&type=application/pdf. I can not even get that by a right click+ sent to email to work.....Yup I'm Belgium and dutch......so i hope i made my idea clear by not using the translate apps and just my brain......:)

Hi, really thank you for your great work.

1. My question

I observe that in other editors like VSCode, Sublime Text

If nothing is selected, and I press Ctrl+C, and Ctrl+X the current line would be copied/cut

meaning while in Thunderbird nothing is copied/cut.

※I write only text mail

1. My suggestion

Is it possible to implement this feature? Would be very convenient.

Norton 360 updated last night and now Thunderbird isn't working.

I tried logging in to Thunderbird but it kept saying my certificate was wrong and refusing to check my emails. I tried to click "add exception" but it didn't help.

It also kept saying its own homepage was a security risk and blocking it.

I figured it was Nortons new update, but have no idea how to fix it. I turned off Nortons Email Protection, which didn't help. So I uninstalled Thunderbird and reinstalled it.

But now its saying it cannot login to the outlook server when I try to add an email account. I know the information is correct, all I can guess is that Norton is blocking it somehow?

Any idea on how I can fix this?

Hi, I've received the email below from Microsoft today.

I have 15 email accounts linked to Thunderbird mail and use up to 5 of them daily. Sometimes 'instant' communications on one or more of my accounts can be important.

Will Thunderbird mail still function in the same way from 16th September?

I apologise if this question has been answered somewhere else. I searched but could not find it.

"The safety and security of your information is top priority for Microsoft. To help keep your account secure, Microsoft will no longer support the use of third-party email and calendar apps which ask you to sign in with only your Microsoft Account username and password. To keep you safe you will need to use a mail or calendar app which supports Microsoft’s modern authentication methods. If you do not act, your third-party email apps will no longer be able to access your Outlook.com, Hotmail or Live.com email address on September 16th.

What do you need to do?

If you are receiving this email, you are currently using an email or calendar app that uses a less secure authentication method to connect to your Outlook.com email account. You will need to upgrade your third-party mail and calendar app to a version which supports modern authentication methods.

Microsoft provides free versions of Outlook for your PC, Mac, iOS, and Android devices which can be easily downloaded and connect to your email account. Using an updated version of an Outlook application will ensure you are connecting in the most secure way.

How can you set up your Gmail, Apple Mail, or other third-party mail application?

Various non-Microsoft applications will have their own steps for connecting to your Outlook.com email account using modern authentication methods. See our help article - Modern Authentication Methods now needed to continue syncing Outlook Email in non-Microsoft email apps. However, you may need to contact the creators of those applications to provide you with instructions. In many cases, simply removing and re-adding your account with the latest version of that application will configure it to use modern authentication methods."

I have 4 accounts with different names but all with the same domain name (name1@samedomain.com, name2@samedomain.com ...). The first one set up perfectly and works. The 2nd and the 3rd can't retrieve mail from the server (didn't try the 4th yet). The SSL ports are the same for all. The passwords happen to be the same for all. (I haven't tried changing the 2nd and 3rd passwords as that seems unlikely to be the problem.) When initially setting up the 2nd or the 3rd I get a "Sending of password for user name2@samedomain.com did not succeed. Mail server pop.yyy.zzz responded: [AUTH Authentification failed." I've checked the passwords on both the client and the server ends multiple times and they are the same. Then, of course, periodically I get a pop-up with "Login to server pop.xxx.yyy with username name2@samedomain.com failed. When I go to the Account Settings screen with the 3 accounts and click on each Server Settings one after another, the only thing that changes is the User Name, yet the first account receives mail and the other 2 don't so everything is correctly set up. As an aside, I CAN SEND emails from the 2nd and 3rd accounts but can only RECEIVE and SEND from the 1st. Any help appreciated.

As of today, my inbox has 7,563 emails, but none of them are displayed in the messages pane. I can see them if I go to All Mail, but I'd like to be able to use my inbox.

UPDATE SINCE THERE DOESN'T APPEAR TO BE A WAY TO DELETE THIS POST - I CLICKED "REPAIR" AND IT'S NOW FIXED.

As of December 1st 2023, one of my gmail accounts in thunderbird stopped working. Every time I check messages, I get the Oauth prompts to allow thunderbird access to the gmail account, I click through without error messages, and I can see the rights were granted to Thunderbird in my account, but Thunderbird is unable to connect. If I check saved passwords, I see it has not saved an OAuth password.

Things I have done: (1) Verified everything in this article: https://support.mozilla.org/en-US/kb/automatic-conversion-google-mail-accounts-oauth20 (2) Verified that IMAP was enabled on the gmail account (3) Checked the settings against my other gmail accounts which are all working, I don't see any difference. (And this account was working up until December 1st, along with all my other ones which are still working)

Anyone have any ideas what might be causing this?

Version 115.8.1 (64) I block messages by domain (domain.com), rather than whole addresses, because spammers are constantly changing their whole address (nutjob@domain.com). The filters don't always catch them when they arrive, and then they sit in the folder, indefinitely. The "Manually Run" and "Periodically, every 10 minutes" options are both selected. The "Periodically..." option does not appear to be working (as I expect it to), so I eventually will go and hit the "Run Now" button to get rid of unwanted mail. I can also quickly delete them using the "Run Filters On Folder" option in the "Tools" menu. It would be great if the filtering worked automatically. Thanks

I have noticed an issue with lists (bullet & numbered) for a while now and thought it was about time I checked to see if it can be sorted!

If I start a new message and there is no text and then I press the Bullet button then this is OK.

However, if I.....

• Start with a blank message
• Type a line of text
• Hit Return twice
• Press the Bullet button - this moves the cursor up to previous line
• Press the Bullet Button - this moves the cursor up to the end of text on previous line
• Press the Bullet button - this put a bullet symbol at start of the line of text

This makes it very frustrating trying to add a bulleted list in the middle of a message.

I saw a previous thread when the OP was having the same problem and his solution seemed to be connected with his HTML signature, but I don't have a signature set up.

This is version 115.9.0 (32-bit) running on Windows 10.

Any suggestions would be gratefully received!

Good morning, On 20/07 I noticed that Thunderbird duplicated all the defects. The option to remove duplicates does not work - no duplicates found. How can I fix this?

Since update to ver 128.1.0esr the "new subfolder" feature does not work (does not show window to name new folder). I have many subfolders and I rely on them heavily. I tried restarting Thunderbird, then Windows. I ran in debug mode with no success. I downloaded and installed 128.2.0esr again. No change.

Is it possible to go back to the earlier version? Which is? Thanks, Frederick

I have a very old computer with windows 7 and Thunderbird 11.5.14. 0 32 bit I have finally got a new computer with windows 11 and have installed Thunderbird 128.1 ESR 64 bit I tried to export from the old version but it will not install on the new version. How do I move my contacts from the old one to the new one - contacts are all I care about , I can get the email by logging in. There doesn't seem to be an export for just contacts.

Im willing to put them in something like xcel as a csv if needed. thanks for any help.

I have two Google (yes, Google, not gmail) accounts. When setting up my gmail in Thunderbird, I was prompted to enter the Google account. I have entered the wrong one. Consequently, I cannot access my gmail: "Unable to log in at server. Probably wrong configuration, username or password."

I have tried all ways I have found in this forum to get rid of it again, such as editing the prefs file, but to no avail.

How can I remove the Google account from the Thunderbird settings to be able to insert the new one?

Thanks for your help in advance, Matt
