I am using Outlook as my email client. I have recently been getting an Internet E-mail popup asking me for my user id and password even though I did not change anything in my settings or computer. The popup happens intermittently although I suspect it is when the system is trying to retrieve email. Using Windows 7. What could be causing this and how do I fix it? Microsoft seems to offer to support and they said I should contact my internet provider. Stopped here first.
