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

[PeterOR]

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 again, @PeterOR 

As you have told me in your message today at 03:08 PM, that you can send normally in TalkTalk webmail, you should now check some settings in Thunderbird.

Go to Thunderbird Settings --> Account Settings --> Outgoing Server (SMTP) settings, which is the last option, in the list of options on the left. Click on 'Outgoing Server (SMTP)'. Then click 'Edit'

The correct settings here, for Thunderbird's 'Outgoing Server (SMTP)' are:

Server Name: smtp.talktalk.net
Port: 587
Connection Security: StartTLS
Authentication Method: Normal Password
Username: your full tiscali.co.uk email address

Once you have checked these, you should be able to send emails in Thunderbird as well as webmail.

Good luck.

Bill

Perfect! Let me know how you are accessing your email service. Are you using the TalkTalk webmail ( https://apps.talktalk.co.uk/appsuite) or using an App or Program from your device?

-TalkTalk Webmail / Through the TalkTalk website
-App or Program on your device
-Both (TalkTalk Webmail and Apps or Program)

-Fez. 

[PeterOR]

Yes, I can send via webmail.

I am using a Windows 10 pc

[nomfezeko-TT]

Thank you. I need to know what device are you using when accessing your email?

-Fez

[PeterOR]

Yes

[nomfezeko-TT]

@PeterOR Could you please kindly confirm if you currently have access to the internet?

-Fez.

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?

Bill

[PeterOR]

Yes, certainly.

[nomfezeko-TT]

Thank you, we will need to conduct checks on our end so we can find the cause of this issue and a possible resolution to it, can we start?

-Fez. 

[PeterOR]

Everyone.

[nomfezeko-TT]

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

-Fez. 

[PeterOR]

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)'."

[nomfezeko-TT]

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

-Fez

[PeterOR]

Yes, I can login using the webmail link.

[nomfezeko-TT]

Thank you for the update, are you using the webmail link provided to access your emails?

-Fez. 

[PeterOR]

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.

[nomfezeko-TT]
