Is there any Service that I can use to sync my contacts and calendar between multiple Windows 8 and Mac OS X devices? I currently have all my data at iCloud and previously at Google, but Google can't sync to Windows any more. Is there any Service I can use that supports protocols that OS X and Windows 8 (Outlook) can use?
I use Google for both contacts and calendar on Windows 8 and OSX Mountain Lion.
Both operating systems have built-in Google sync capabilities.
