Uninstall multiple versions of Office

The first and most common reason iCloud installation could not start is that you have installed multiple versions of Office on your computer. To fix the problem, you need to uninstall all the versions and reinstall only the latest version.

First, run the Programs and Features program to uninstall the apps. (Click on the Start menu, type "Programs and Features" and click Have Access.)
Browse the list of apps and uninstall any Outlook apps you find (right-click > Uninstall).
Once this is done, download the latest version of Outlook and install it on your computer. Alternatively, you can get the version you used before, but make sure you install the latest updates for it.
Now try to sync with iCloud again.

Restore iCloud data file

In Outlook, choose File > Account Settings > Account Settings > Account Settings > Account Settings.
Select the data file > iCloud > Erase tab.
Close Outlook
Open the iCloud app (select Windows > Control Panel > iCloud).
Select Set up iCloud contacts, calendar, and tasks in Outlook.
Once the installation is complete, open Outlook.

You may be prompted to enter your iCloud password, depending on whether or not you have already registered it.
