Blocked sending anyemails by TalkTalk

Kerry47 — Wed, 11 Feb 2026 09:20:34 GMT

Every time I send an email to anyone one any device by any method I get the message that I am blocked by TalkTalk from sending mail. Tried Help chat but they cannot help!!

I get this message back and sending message stays in my drafts folder:

Message could not be sent to the following recipients: *********** <*********@outlook.com> (554 - 554 5.7.1 <*****************@tiscali.co.uk>: Sender address rejected: You are blocked sending mail
)

* used for data protection. Doesn't matter who the email is sent to.

How do I unblock the account?

Hi @Kerry47 I will be able to assist you with your query, can you confirm if you are accessing your email via webmail or using a 3rd party?

Hi Mandisa,

As per my original message:

Every time I send an email to anyone one any device by any method .

Which means by laptop, PC, Phone, Webmail, Outlook, MS Edge. Firefox, Chrome and from a different Internet connection.

I understand, I will be able to run checks for you, you will need to use webmail for now while I run checks that you are unable to send emails.

Hi @Kerry47 please confirm if you are able to receive emails okay or are you also having issues?

I understand, thank you for confirming. Is the email address that you are querying linked to your broadband account or does he have his own TalkTalk account?

He has his own TalkTalk broadband and account.

@Kerry47 Thank you for the information. I completely understand you’re trying to help your father‑in‑law with his email issue.

As this email address is linked to his own TalkTalk account, we do need to speak with the account holder directly before we can run any security checks or make changes on the account. This is to protect the privacy and security of the customer.

What needs to happen next
Your father‑in‑law will need to log in and contact us here on the Community and we will run checks for him.
OR
He can contact us by phone and give permission for us to speak with you on his behalf, you will be assited on the over the phone.
Once security is completed by the account holder, we’ll be able to investigate the issue fully.

Please let him know, and as soon as he gets in touch we’ll pick this up again right away.

What number does he need to call?

I tried to logon to Community from his house yesterday but system would not verify him, kept sending logon code but was not valid.
