Get all application proxy apps published with no certificate uploaded
The PowerShell script example lists all Microsoft Entra application proxy apps that are using custom domains that don't have a valid TLS/SSL certificate uploaded.
If you don't have an Azure subscription, create an Azure free account before you begin.
Note
We recommend that you use the Azure Az PowerShell module to interact with Azure. See Install Azure PowerShell to get started. To learn how to migrate to the Az PowerShell module, see Migrate Azure PowerShell from AzureRM to Az.
The sample requires the Microsoft Graph Beta PowerShell module 2.10 or newer.
