Thunderbird 156 wanted to keep getting a response that my business associate's email account did not exist. I had to have the recipient contact me to get Thunderbird to successfully deliver the email I first sent and responded to. Is this not some Java bug to the domain?

I have no idea what happened to my Thunderbird. I think it might have been an update, because all of my folders are not where they were, everything in the folders are sorted by groups like today, or older. I noticed a bunch of my emails are now in folders marked as a Userfolder#. The emails it contains are those that normally should be in a properly named folder, only those named folders are grayed out. Another issue is that when i try to open an email, it opens it as if I want to reply to it. If I just want to read the email, I have to right click on the email and select open to read it. I have 2 spam folders, no idea why, nothing saves to my draft folder I found out today, I just dont know what happened! I dont think I did anything but I dont know now, as Im beginning to doubt myself. It's been this way for a few days.

I keep getting the following error when trying to download emails from yahoo.mail: Authentication failure while connecting to server pop.mail.yahoo.com Have hundreds of emails sitting in yahoo.mail that I need to load onto my desktop. Any help is appreciated!

I have been unable to send emails for two weeks. I continually get error messages such as "An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: EHLO requires valid address." Another message says to check the SMTP outgoing server settings. I am using Windows 10, which has worked for several years. My email server is mail.twc.com and Spectrum. I can send emails via my iPhone or via the Spectrum webmail, but not through Thunderbird. I have examined my SMTP settings several times and have tried various combinations of settings. None has worked. Spectrum has no help and refers me to you. Can you help? Thank you, Andrew Gurian

How can I change an IMAP server on an existing T-bird account after T-bird deleted the saved password and IMAP server for that account? I tried to change the IMAP server address for an existing T-bird account, but T-bird and/or my ISP deleted the saved password and IMAP server entry for that account, so T-bird cannot get incoming E-mails. I would like to add an/the IMAP server back to the account without deleting the account, adding all of its settings again, and waiting 6 hours for T-bird to re-download all of the most recent 10,000 messages in the Inbox and all of the 15,000 messages in other folders again. The SMTP server and its saved password are still in the Saved Passwords table.

Hi All,

I am on the latest release 156.0 on Windows 10. I have 3 email accounts, 2 gmail and 1 yahoo. The Yahoo account has been giving me problems since the last 2 weeks. Mind that yesterday I have a completely new Windows 10 installation so also TB installation is new.

I have renewed the Oath login, all messages were downloaded without a problem, but once in a while I get different notifications about server errors such as the ones below. There's also a third type of message error but haven't been able to get a screenshot of it.

Could someone please help me to solve this issue? I really don't understand why the problem is intermittent. Thanks in advance!

I've been using Thunderbird on Windows 10 since last year sometime. Currently I'm on version 151.0.1.

I've 4 x mailboxes here and since yesterday, 3 of them show me an unusual message when checking for emails. I tried attaching a screenshot but although the screenshot uploaded, I couldn't find a way to insert it here. But the message says Unable to write the email to the mailbox and asks me to check if I've write privileges (which I have) and to cheek the available disk space.(currently 101GB free).

The message is happening 2 or 3 times each day and lasts for about half an hour, then everything works fine again. Has anyone else seen this??

Hi Today, several emails that I have received, which I think were sent from an Outlook account, have, instead of what I would expect to see as the sender's address under correspondents, have Microsoft account team <account-security-noreply@accountprotection.microsoft.com> When I click on the email, I can see the genuine sender's address This has only happened today At least one of the emails that I received came from someone that I know uses Outlook Any ideas? Thanks

I've been using Thunderbird version 155.0 with only a few issues (reported in other posts).

To investigate one of the issues I've had to create a new profile for testing. I've managed to set everything up except for my default font for outgoing emails. If I send an email with say, four lines of text, I can format each line to be a different font and the received email reflects the different fonts for each line.

But Thunderbird isn't remembering the last selected font. So if I send a second email (without re-selecting any font) the recipient receives it in some naff mono-spaced font. I guess there's somewhere where I can set up the default font for my outgoing emails but I haven't managed to find it yet. Can anyone help?

I am trying to send an S/MIME encrypted email from Thunderbird to:

jobcenter-chemnitz.netzwerkpartner@jobcenter-ge.de

The recipient certificate is provided by the official certificate directory of the German Federal Employment Agency (Bundesagentur für Arbeit).

I downloaded the recipient certificate and successfully imported it into Thunderbird under:

Settings → Privacy & Security → Certificates → Manage Certificates → People

The certificate is displayed correctly there. The email address contained in the certificate is:

jobcenter-chemnitz.netzwerkpartner@jobcenter-ge.de

The certificate is valid from July 29, 2026 to July 29, 2028 and includes E-mail Protection and Key Encipherment.

The required CA certificates are also installed:

BA-Class-1-Root-CA-4:PN BA-VPS-CA-11:PN

However, when I compose an encrypted email to this exact address, Thunderbird reports:

“You have selected to encrypt this message, but the application failed to find an encryption certificate for jobcenter-chemnitz.netzwerkpartner@jobcenter-ge.de.”

Under S/MIME → Recipient Certificates, Thunderbird also shows the certificate as “Not found”.

I have already tried:

deleting and re-importing the recipient certificate completely restarting Thunderbird after importing it manually typing the recipient address in lowercase without using autocomplete checking the complete CA certificate chain temporarily disabling OCSP

None of these changed the result.

My own personal S/MIME certificate works correctly. As a test, I can compose an encrypted email to my own email address without any certificate error. Therefore, the basic S/MIME configuration and my own certificate appear to be working.

When I reproduce the problem with the Thunderbird Error Console open, I get:

NS_ERROR_ILLEGAL_VALUE (0x80070057)

related to:

nsIMsgComposeSecure.beginCryptoEncapsulation

This seems similar to Mozilla Bug 2021265, where a manually imported recipient certificate is visible in Certificate Manager but is not found when composing an encrypted message.

Is this a known issue in Thunderbird 140 ESR, and is there a workaround for using this manually imported recipient certificate?

I’m trying to understand how Thunderbird handles links to online media when an email contains a link to a photo or video rather than a normal attachment.

For example, if an email contains a link to public Instagram media, I may open it in the browser and use a browser-based option such as Indown.mobi to work with the media. Is there any Thunderbird setting that affects how these external media links are opened or handled?

I’m mainly interested in understanding whether Thunderbird treats these differently from normal attachments and whether there is a recommended workflow for managing them.

“My Spectrum email address is [redacted]@charter.net. Spectrum webmail can send and Thunderbird can't receive or send. The outgoing server is mobile.charter.net and the connection times out. I tested the connection from my computer and ports 587 and 465 both respond successfully. Thunderbird is set to No Proxy. when i tried to send today, it gave me this message, "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) mobile.charter.net timed out. Try again." i contacted spectrum about this and now when i try to send, it says nothing and the message never arrives.

I have an address book setup with a number of what I'll call sub books for want of a better name. I used to be able to copy a contact from the address book to a sub book. I have either forgotten how to do that or something may have changed. I tried to drag & drop the address from the main book to the sub book but that doesn't work any longer. What am I missing here?

Running Win10, all the sudden I'm getting Not Responding messages, failures to connect to server, and slow deleting of emails. I tried everything: uninstalling/reinstalling; running on troubleshooting mode; checking compatibility. Nothing works. Any ideas?

Thank you

I cannot connect Thunderbird to a primary outlook.com account. I can connect to an outlook.com alias account. I have confirmed this on two Windows 10 machines. I can connect to the primary outlook.com account from an iphone and an ipad. Is Thunderbird broken?

My office has moved our emails onto a microsoft exchange server. I backed up my emails, removed all accounts, settings, passwords and then rebooted. Found instructions online. Went to add account > New mail. The account hub page after selecting "new mail" asks me for my name and email. after I input that, it then allows me to continue. It says "account settings found automatically" and offers me 3 options - IMAP, Exchange or Exchange (with owl add on). I select Exchange. In the left hand box next to the options, It shows all the email details and then at the end "authorisation by normal password". I try to click "edit configuration" but nothing happens, so I select "continue". The page now asks for a password. I input the password the IT shop guy gave us and then press continue but get an error message at the top - "unable to log in at server. probably wrong configuration, username or password". The only inputs available to me are the password line and the "back" or "continue" buttons. No trigger of my web browser occurs in order to input any Authorisation on microsoft via my Authenticator app.

What can I do (besides using OWL - I don't have the spare funds for yearly subscription)?

Thanks

In the last month or 2, when I delete an email it does not show in the trash folder. I can wait from 5 minutes to even the next time I reboot my puter to finally see it it trash. Sometimes it sends it to the all mail or important folder instead of trash. And if I delete from there, it still takes tons of time to end up in the trash folder...if it even gets there. This seems to be getting worse by the day. I have clicked repair folder, no change, I have cleared Thunderbird's cache, no change. It's also now taking way too much time to load an email that contains a picture. This happens with at least 3 of these gmails. I'm at a loss here and extremely frustrated and about to change these gmails from imap to pop. win10 and TB is up to date. But it doesn't compact folders as much as it used to either. Any help appreciated
