Sweet Mother of God.  After losing all my hair, I finally found a solution from digging around at http://answers.microsoft.com/en-us/office/forum/office_2013_release-outlook/outl ook-2013-keeps-disabling-icloud-add-in/5….
 
The solution:
 
1) Run Outlook AS ADMINISTRATOR.
2) Go to File > Options > Add-ins.
3) Click GO next to COM Add-ins.
4) Select the iCloud Outlook Addin and REMOVE it.
5) Close and restart Outlook AS ADMINISTRATOR.
6) Go back to File > Options > Add-ins.
7) Click GO next the COM Add-ins.
8) Click ADD and find APLZOD32.DLL on your machine.
9) Close and restart Outlook normally (NOT as administrator.)
 
Now my calendar is syncing properly.

A very low % of users (only corporate volume licenses) have access to the MSI version of Office 2013, which 
would leave some 95% of iPad/iPhone users without the ability to use iCloud. I know iCloud works with 
Office2013 C2R because I use it.
