Login to server mail.talktalk.net with username (xxx)@tiscali.co.uk failed.

Starting today, I am getting the above message when I try to open my Tiscali emails on my Windows 10 computer.

Can you suggest a reason for this?

Thanks

Hi @PeterOR this small, possible explanation, is no immediate help to you but we are seeing this issue a lot at weekends, I strongly suspect changes are going on in the background and as such email addresses are becoming unavailable for 12 to 36 hours.

your post has been escalated and you should hear soon. In the meantime please check your community profile and add your landline number and/or account number so your account can be identified. Please don't post personal information here.

@PeterOR,

There's no staff support on here before Monday. Chat is available during the day on Sunday.

Please keep issues connected with Thunderbird / Tiscali within this one thread as they are possibly part of the same problem and it's much more efficient to focus replies here if the issues seem to be associated.

Please follow up on this thread.

As an update on this query, I have changed my Tiscali email password, and can now receive incoming emails, but still getting the same error message when trying to send.

Great, so you are now able to receive the emails but cannot send, is that correct?

Yes, that's correct. When trying to send an email, I get the message: "Sending of the message failed.
Unable to authenticate to Outgoing server (SMTP) smtp.talktalk.net. Please check the password and verify the 'Authentication method' in 'Account Settings | Outgoing server (SMTP)'."

Is this happening when you are trying to send an email to a certain email address or just everyone?

Hi, @PeterOR

The answer you gave on ‎26-06-2025 12:58 PM seems to be a response that Thunderbird would give.

Did you actually try sending anything via TalkTalk webmail at https://apps.talktalk.co.uk/appsuite/ ?

Can you send via TalkTalk webmail?
