Emails not connecting to server

Same issue here. It's not the password. Outlook no longer connecting, prompts for password, so looks like security settings in Outlook no longer work. Have you changed anything in the last few days ?????

Does your TalkTalk mailbox work via webmail?

Select here:  Sign in to TalkTalk Mail

Enter your full TalkTalk Mail email address, select Continue and enter the password, select Sign in.

What version of Outlook are you using and with what Operating system?

Screenshot the incoming and outgoing server settings, image edit to obscure the first part of the talktalk email address and upload here using the camera icon above this Reply area. I'll take a look and advise further.

Confirm also that the password meets minimum security requirements. Must be at least 8 characters although I recommend 12 - 15. Must be multicase letters and at least one number and one symbol. Weak passwords may work via webmail but can be rejected by the mail servers.
