I cannot receive e-mails as I keep getting asked for the password which is not accepted.

I have Windows 10. Up to a week ago I was receiving and sending e-mails okay

My laptop with the same set up is fine.

I can access my Webmail ( Tiscali )

I have tried WLM repair and checked all the passwords correspond.

Nobody seems to be able to come up with an answer as I see many people with the same problem on Forums.

                                      Please advise
