Error in Setting up email in Windows live

Hi Support,

The customer is having issues setting this up on his laptop. He is using Windows Live. He said he can see the emails that have come through to info@npssecurityservices.com.au but he keep receiving a popup that asks him to enter his email address and password. When he fills it out, it pops up again. Do you know what the issue way be?
