This is the message I get when sending an email to 1 recipient. The problem started after sending a 58 group message,  without problem previously.

Talktalk the provider, say its not their problem because their email works fine, microsoft cant sort it and then say its not their problem and I should look on answers.microsoft.com. Does anyone have any suggestions as to how I send emails on my main email address please?

The message could not be sent. The setting for your outgoing email [SMTP] server might need to be configured. To find the server settings for *** Email address is removed for privacy ***', please contact your email service provider.
