Apr 15, 2016 10:05 AM in response to FrostyOfTheNorth 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.

Diane Poremsky January 21, 2015 at 9:04 pm | Permalink 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.
