Cause
This issue may occur if one of the following factors is true:
- The PowerShell version that you are using is higher than 5.1. The Azure Active Directory Module only works with PowerShell 3 to 5.1.

- Identify the PowerShell version by running
$PSVersionTable. - Run the Azure Active Directory Module for Windows PowerShell as an administrator. To do it, select Start, select All Programs, select Windows Azure Active Directory, right-click Windows Azure Active Directory Module for Windows PowerShell, and then select Run as administrator.
- Set the execution policy to Unrestricted. To do it, type the following cmdlet, and then press Enter:PowerShellCopy
