Q: icloud is not syncornizing with outlook 2016 Business

This was taken from the Event Viewer, If you are seeing this... then this is the problem.

Faulting application name: AppleOutlookDAVConfig.exe, version: 4.8.24.0, time stamp: 0x56cc1f98

Faulting module name: mso20win32client.dll, version: 0.0.0.0, time stamp: 0x57784745

Exception code: 0xc0000005

Fault offset: 0x000be925

Faulting process id: 0x1100

Faulting application start time: 0x01d1ddcd57beda4b

Faulting application path: C:\Program Files (x86)\Common Files\Apple\Internet Services\AppleOutlookDAVConfig.exe

Faulting module path: C:\Program Files (x86)\Common Files\Microsoft Shared\Office16\mso20win32client.dll

The problem is that there is a break down in the security setting with the communication between Outlook and iCloud. in 16.0.6868.2067 iCloud Function and you could upgrade to the newer version. But if you just bought or order the Office365 and installed it you would have 16.0.6925.108 or the newer version which is 16.0.7070.2026. These version will not allow the AppleOutlookDAVConfig.exe program to create a iCloud Profile. But if the profile was created with an early version of Office365 before the update. It works just fine.

So the problem is not with iCloud main program, it is with their AppleOutlookDavConfig.exe tool.

5.2a or 5.3 needs to come out to fix this..

I can not take full credit for this BUT this dose work....
