I am in bowling green, I too have been getting outlook asking for my password, or in some causes getting the too many message error. I contacted insight, and they said it wasn't anything on my their end. Because if a person was sending a bunch of email they could be flagged in their account, but they said it the problem was mostly outlook 2007. I deleted the account in outlook, and recreated it and it worked for a while. Now it is doing the same thing, and I have a friend in lexington,ky hers is doing the same thing.
I even have my iphone pulling mail from insight and I will get a server error every now and then.
What is going on with insight?
