I am working on a Windows 10 PC, and use Windows Live 2011 to manage my email, contacts and calendars.  Until the morning, all was working fine.  Now when running WinLive 2011, I get the message "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."

I don't understand what I need to do to get this running again the way it was, if that's even possible.  I don't want to lose the PC interface.  My email account is IMAP, yet this still does not work.  What am I missing?  I really rely on this interface to work with my email and calendars.  If I decide to use the Mail program that comes with Windows 10, is there a way to store emails offline folders, and contacts and other items offline as well?

Thank you!
