Answer 1

This is typically because of TLS 1.2

Close that command window and open a new powershell window as administrator
Enter:
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12

Then try it again.

Install-Module -Name ExchangeOnlineManagement -RequiredVersion 2.0.5
