AzureAD PowerShell – Code: Authentication_Unauthorized

After connecting to your Azure AD using the Connect-AzureAD cmdlet, you will try to retrieve information about your Azure Active Directory, but you may get the following error:

Get-AzureADDomain : Error occurred while executing GetDomains
Code: Authentication_Unauthorized
Message: User was not found.
HttpStatusCode: Forbidden
HttpStatusDescription: Forbidden
HttpResponseStatus: Completed



This error means that you are connecting to Azure AD without privileges or you are conencting to the wrong Tenant ID.

In this case, TenantDomain is “User” which is wrong. To ensure connection to the expected Azure AD Domain, the tenant ID must specified:

Note: The tenant ID can be retrieved using the Get-AzureRmContext cmdlet.

Now you can run the Get-AzureADDomain cmdlet and you will get all the information about your Azure AD.
