"There was an error when attempting to connect to the Windows Live Calendar service. If the error persists, check to see if there's an upgrade of Windows Live Mail available or contact a service representative."

   This message opens every single time I open mail. There doesn't appear to be any solution anywhere that works. Anybody know how to stop this? It's annoying and frustrating that there's no answer to the problem. And yes, I've uninstalled/reinstalled and tried un-checking mail boxes on left side of page...thanks.
