I did a clean install from scratch of Windows 10 and Outlook 2013 and now Outlook 2016 is not compatible w/iCloud. My initial fix was to leave iCloud disabled in Outlook and then turn it on to sync. Then I would disable it, otherwise Outlook would hang on startup.
Now that I upgraded to Office 2016, iCloud will not even connect to Outlook, despite it recommending a repair.
Apple certainly had enough time to test iCloud with Office 2013/2016 and Windows 10. They would be the first one to complain if Microsoft ignored the Mac for Office 2016.
Does anyone know when Apple is expected to release an upgrade to iCloud that will work with Windows 10 and Offiice (2010, 2013 & 2016)? All my contacts are in iCloud.
