icloud for outlook cannot install because icloud server not responding

Greetings WorldsGreatestDetective,

It appears that you're having an issue connecting to iCloud for Windows. We'd like to provide you with a few steps that may be able to get you connected:

"Things to check first

Before you change your security software's setup: 

• Make sure that the date, time, and time zone are set correctly on your computer. Learn how to update these settings on a Mac or on a PC. 
• Log in to an administrative user account, not a guest account. Learn how to do this on a PC. 
• Update to the latest version of iCloud for Windows or update to the latest version of iTunes.
• Make sure that you have the latest software on your Mac or on your PC.
• Make sure that you set up Windows Hello. Learn how to set it up. 
• Make sure that you only have one type of security software installed. If you have more than one type of security software installed, you might experience performance issues.

Test your connectivity

1. Check your hosts file to make sure that it's not blocking iTunes from communicating with Apple's servers.
2. If you’re having issues using AirPlay, Home Sharing, iTunes, or Remote, test the connectivity between the computers or devices in your house. They should be connected to the same network and subnet in order to function properly.

Test your security software

If you still have trouble after you test your connectivity, your security software could be interfering with your computer's connection with iCloud for Windows or iTunes.

In some cases, it might be necessary to temporarily remove your security software to isolate an issue. Some Internet security apps don’t uninstall completely, so you might need to download and run a cleanup utility for your security software for it to be completely removed.

Work with your security software provider to allow the complete list of ports and services that Apple products use or if you need help with uninstalling their software."
