Hi I Have just added my wife's email address to the desktop where I use Thunderbird. It has downloaded all of her emails from the server but when I try to send an email I get the following error message. I haver tried changing the SMTP server to smtp.talktalk.net, but it makes no difference. I have two of my own talktalk email addresses set up with smtp.dsl.pipex.com and they work fine. Any help would be appreciated.
Sending of the message failed.
Unable to authenticate to Outgoing server (SMTP) smtp.lineone.net. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'

Just as a test, set up the lineone email address in Windows Mail on the same computer to check that a different email client is working.
Select the settings cog icon bottom left
From the Settings panel select + Add account
Scroll down and select Advanced setup
Select Internet emailEnter the lineone email address in full in both the Email address and Username boxes
The Sync options should look like this:

Ah, I have seen copy and paste fail because of added spaces. What I'd do in this case is delete the SMTP password entry for the lineone email address. Then on the next send of mail you'll be prompted for the password. Tick to remember the password, enter the password and this time it ought to work.

Thanks for the reply. Incoming mail works fine, but I will change the settings as suggested to future proof.
The password is correct as I am not typing it in so it is not a typo. It is a 12 digit generated password and a mixture of upper and lower case numbers and symbols. I have copied and pasted it in and it is the same one being used for the incoming mail server. My wife can send emails from her Kindle and from the webmail, just not from Thunderbird on the desktop.
I also use Thunderbird for another two talktalk accounts, my Gmail account and a Outlook Office account for work. They all work fine and been set up by simply typing in the email address and password and leaving Thunderbird to do the configurations.

The Server Settings: what needs changing
The IMAP incoming mail server
Port: 993 (not 143)
Connection security: SSL/TLS (not STARTTLS)
The outgoing SMTP server settings are correct. However, I would normally expect to see the Description as the email address (Username) but it says not specified so that tells me something is not usual. Either you've edited out the description via the Edit function for the outgoing server (instead of image editing) or maybe the outgoing server selected is not linked to the lineone email address.
The outgoing SMTP server details / password are worth carefully rechecking as mail sending should work unless there's another reason for the send error.
Heads up that a weak password can be rejected by the mail servers even if a sign in and sending via webmail does work.
Worth checking sending via webmail just in case there's a different error message on sending.
Select here: Sign in to TalkTalk Mail
Enter your full TalkTalk Mail lineone.net email address and password, select Sign in.
Compose and send a message to the same mailbox so you can immediately check the sending and receipt.
The Reset your password now button in the help article Changing your email password will take you to password reset and recovery.
If you have set up password recovery options, in advance, that you recognise from the *****hints, then you can send your alternate email address a link or your mobile a 6-digit code to authorise a password reset. Upgrading the password to a new ultra-strong, never before used, password is worth doing if there's any chance of the password being deemed weak.

Yes of course we can focus on getting the Thunderbird settings right.
You've seen the advice that the right server host names are mail.talktalk.net for incoming mail and smtp.talktalk.net for outgoing mail and that these apply to all TalkTalk Mail domains.
Screenshot the account settings - incoming and outgoing SMTP server / security settings, image edit to obscure the first part of the email address in front of the @ symbol (Username) and upload using the camera icon, or picture frame icon for a mobile browser, above this Reply area so I can see what you see and advise on changes.
You asked for advice on the certificate. Using imap.lineone.net you will get a certificate error because that host name is not listed on the mail.talktalk.net certificate. Receiving will work unencrypted or by overriding the certificate error simply because the mail is redirected to the talktalk.net incoming mail servers.
For outgoing mail the legacy lineone.net mail outbound is redirected to the smtp.tiscali.co.uk outgoing mail servers and those servers are currently designed as permitted servers for the talktalk.net domain.
So, please do use the recommended mail.talktalk.net (incoming) and smtp.talktalk.net (outgoing SMTP) host names and connection security and port settings I gave earlier. You'll be up to date and will not be tripped up when talktalk cease the legacy name servers along with insecure connection security in a overly long drawn out effort to get all users onto secure mail messaging and the talktalk.net host servers.
You should check the current passwords stored by Thunderbird are correct for both the imap and smtp servers being used by the lineone account. You'll find those passwords under the Thunderbird main menu > Preferences > Privacy & Security > Passwords, Saved Passwords > Show Passwords, confirm Yes.

Hi, many thanks for the quick reply.
A stated in my original post I have no problem with incoming emails to the account so I do not want to mess with them. I have already tried changing the smtp server to smtp.talktalk.net and all of the other smtp settings are as your list. I have changed the smtp back to smtp.lineone.net It could be the certificate as I had some error messages when setting up the account. Can we focus on getting that right.

The email client software / app will require updating of the legacy email settings. All TalkTalk Consumer mailboxes, whether pipex or lineone use the same Email Settings. See TalkTalk Mail Support Hub
On updating the email software incoming, outgoing and some advanced server settings, you'll possibly be asked to accept a new certificate (yes, accept) and to enter the email password so have the current password ready. Tick to remember or save the password before entering it.
Supported* email client and app settings are:
|Account Type||IMAP (recommended) or POP3
|Username||Full email address|
|Incoming mail server name||mail.talktalk.net|
|Incoming Port (IMAP / POP3)||993 / 995|
|Incoming Connection Security||SSL/TLS
|Outgoing mail server||smtp.talktalk.net|
|Outgoing Connection Security||STARTTLS
|Outgoing Authentication Required||Yes with password
|Authentication Method||Normal Password|
It's also important to make sure the email address is added to a TalkTalk Consumer customer MyAccount to avoid restriction to webmail only access and possible deletion.
TalkTalk Mail Plus is the mail only subscription service for TalkTalk Mail users in the UK that are not home broadband customers.
* Email clients, apps and devices that do not support secure mail using a minimum of TLS1.2 connection security are not supported.
