What's causing this error message?

Hi, since yesterday, whenever I try to get my email or open another application such as Weather or Stocks, I get this message: Cannot Get Mail. The connection to the server "pop3.live.com" failed.

Does anyone know what's causing this message? Is it my phone or my service provider (Rogers). Up until yesterday, everything was working fine. Thanks.

You need to check your e-mail settings. Maybe you have changed your password for e-mail or something else.

I haven't changed any passwords, but did just re-enter them to see if that was the problem, but it's not. However, this isn't just mail, but the Weather, Safari and Stocks apps, as well. In essence my phone is no longer connecting to the internet.
