I got this message yesterday, when I was trying to send an e-mail with Windows Live Mail.

 My Internet Provider (IP) says that my ISP is ok, as I have been able to send e-mails via my Web Mail

It is also asking me to log on ten telling me I am sending the incorrect password

It is very frustrating, as I sent over 5 hours yesterday with an online help provider, without a good result. They say that it is the ISP address, whild my IP is saying a;ll is fine .... contact Microsoft ..... so here I am
