How to allow PowerShell to connect to Exchange Server over IP address

Problem:

You need to be able to connect with PowerShell to your on-premises Exchange Server by using its IP address instead of its FQDN or hostname.

Solution:

In order to allow PowerShell to connect remotely over an IP address, PowerShell Virtual Directory in IIS must be configured for basic authentication. Follow the steps below to do that:

1. Run  Exchange Management Shell on the Exchange machine to which you want to connect over the IP address.
2. Execute the cmdlet below:

   Set-PowerShellVirtualDirectory -Identity "PowerShell (Default Web Site)" -BasicAuthentication $true
