Sent e-mail being stored in outbox

I brought a Dell Laptop and was wanting to sent a Excel file to the desktop of my new Laptop. With my surprise all of my e-mail that I send is going to my outbox and just standing there.

I have Bellsouth as my e-mail carrier and on my new laptop it is Windows Live (Hotmail).

Here is a error message that comes up; (Task "masongezi@bellsouth.net-Sending' reported error (0x800CCC80): 'None of the authentication methods supported by this client are supported by your server.)
When I brought my laptop I did buy a Netgear router and installed it here at the house so that I could use my laptop around the house. Could that be the problem, because my e-mail was working fine.

I have windows XP of my desktop computer, and Vista on the new Dell Laptop.

Any help or suggestions would be appreciated. Thank you in advance.

 

Thank you PeteC. I found some info in the link that made my e-mail work!! Sorry it taken me so long to get back with you. My job taken me away from the computer a while. Thanks again!!!
