> CalDAV and CardDAV are supported on Windows Phone 8 since GDR2 as the method to sync Gmail accounts.
Yes, but it only works with Gmail (and iCloud) accounts, not arbitrary CalDAV/CardDav servers. Some people have had success with adding a fake iCloud account then modifying the server address, but it's not officially supported and really shouldn't be relied on to work properly.
I really hope that Windows 10 Mobile includes official support for CalDAV and CardDAV.
