Neither my wife nor I can access email on our respective PCs. This has been the case for four weeks. We can access email by our Android phones, but we really want to use our PCs. I've tried to resolve the problem and failed. Previous to this failure, I had an account with BT but this was transferred to EE. When I attempt to log in to my mail account, I receive the message "Could not connect ... :the connection was refused". I can also add is that in my Account settings, Outgoing Mail server I see a message "Connection to server mail.btinternet.com:465 failed."

Cannot send messages. I get an error code:

Sending of the message failed. An error occurred while sending mail: Outgoing server (SMTP) error. The server responded: RBL restriction: Blacklisted by Internal Reputation Service - 73.62.119.4.

This is a recent abberation. I've updated to the latest version of TBird. But cannot understand this message or why I get it. Please help as I forward/send many messages daily.

Thank you

Attempting to install Thunderbird on an additional desktop using same address as my original computer has. That was my question:

Lin answered: Please quote any and all error messages you see, in full, verbatim. Screen shots would be OK.

Who is your email provider?

Have you compared all account settings, not just the email and password?

Here's my answer to those questions: "Authentication error" "probably wrong configuration, username or password."

My email provider is MTA (Matanuska Telephone Association) Yes, I currently use Thunderbird in my other desk top and it works fine.

Hi, I use thunderbird as both POP and IMAP through gmail. I keep all my emails on my POP thunderbird desktop client. I use IMAP on my thunderbird laptop client, iPhone, iPad via Apple mail when remote, then download the emails to my desktop.

What I want to do is read emails and set them to archive on my IMA laptop, iPhone, iPad. I know Gmail tags the archived emails. How do I stop thunderbird from downloading the archived emails to my POP thunderbird desktop client?

Thanks! Art

Hi everyone!

I'm trying to log into my email account on the domain example.com via SMTP. The email account is with yandex.ru. When I try to authenticate, it says the SMTP password is incorrect. I decided to try through Outlook, and it worked. What could be the issue?

I have version 153.02esr. Since two days ago I cannot reply or forward messages. It pulls up the appropriate page but there is no box to send, the space is just blank in the upper left hand corner.

I've used Thunderbird for years. computer crashed and I'm trying to install Thunderbird on my new PC. Thunderbird cannot find account. I've checked with my provider several times and all settings are correct. Any ideas? I've also downloaded installed and uninstalled 5 times today with the same result.

Windows 11 Sending, but not receiving e-mails in two OAuth addresses (one university account, one personalised domain gmail) Can't find 'Incoming Server Settings' to check if they are correct Have selected "manual configuration flow" and restarted Thunderbird

Hi, I just installed Thunderbird on a new computer and was super happy about how easy the setup has become for multiple e-mail addresses - however, I have two addresses where I can send, but not recieve e-mails. One is a university e-mail and one a personalised domain gmail - I used both without trouble in Thunderbird on my previous computer. They are both OAuth and the Outgoing Server Settings are correct, but I cannot find where to adjust Incoming Server settings. I've selected "manual configuration flow" and restarted Thunderbird, but still can't see anything new. Where do I find Incoming Server settings now? Thank you for your help,

Lena

It's been almost a week now, and my 2 Microsoft email accounts will not connect to Thunderbird anymore. All was fine for years, but something changed that I can't figure out!?! I have gone to my Microsoft email server and checked that my passwords still work. I even updated one and it works on Microsoft server but not Thunderbird's!?!? I even deleted one email account from Thunder bird to re-install it, but when I tried a fresh re-install Thunderbird still won't connect to Microsoft server??? I'm at my wits end, and may abandon Thunderbird completely if someone there doesn't help me connect!!!

I live in Germany and use t-online for my email. I can receive emails but not send. I have tried to fix it myself but nothing I do has worked. I don't understand all the technical stuff, so this is maybe my problem. Can anyone help me? PLEASE

Maybe there is someone near me in Germany (Obertshausen) by Frankfurt that can Help. I speak German so this would not be a problem.

When sending a message, the email reaches the recipient but is not saved in the sender’s account. This email is not displayed anywhere — neither in the web version nor in Thunderbird. Please help resolve the issue.

Thunderbird demands my password for outgoing SMT server when I go to send an email but when I enter it, system won't accept it even though it is the correct password. I have had this problem for some time and it comes and goes. Sometimes I have ebeen able to send without a problem, then it comes back I had a helpful reply from this forum (can't find who posted it - Mick?) tellling me to go into the error console (Ctrl + Shift + J) and delete eveything in that. I tried that. It worked at first, but now when I do it, it has no effect. And the problem now appears to have become permanent, although occasionally after I have been working for some hours, then suddenly I can send without any problem. Problem hasn't budged though for a couple of days now. This is a mysterious and erratic gremlin, which now seems to have taken root. Any suggestions please? Carol

When attempting to send a web address under "file" tab using Thunderbird, there is an offering "email Link". "email link" does nothing with Windows 11 but worked with Windows 10? I have to copy and paste to send a web address to a mail recipient.

I have 2 accounts. One account is for my normal email address, which contains my usual "Name+Surname@gmail.com The second account is for a fake name (as used on this forum): oldgrantonian@gmail.com

In Thunderbird, my normal email address works fine.

But the last email in my fake email account was on 16/02/2026. I can't send emails from the fake account.

The online version (mail.google.com) is fully up-to-date. I can send and receive emails in both accounts.

I would be grateful for any advice on how to restart the fake account.

Thanks

Thunderbird version 148.0.1 will not send outbound emails since updated to OAuth2. Error message is Unable to Authentic Outgoing server (SMTP) Email account will allow inbound mail , but will not send mail. Have worked through all published troubleshooting steps. Extremely frustrating!
