Azure Resource Graph is an amazing tool in the belt of Az Ops team. It allows to quickly search across all your subscriptions (does it?). Started using Az Resource graph with that pretext that the queries I ran will be run against all the subscriptions I have read access to, Yes it will but there is a catch here! I mostly use Az.ResourceGraph PowerShell module (Why? another post) Found the solution by digging into the source code for the Search-AzGraph cmdlet, if the subscriptions are not specified explicitly then the cmdlet uses a method named GetSubscriptions() Below is a snippet of the method def: The catch is that if no subscriptions are supplied it defaults to subscriptions in the default context. I am not really sure but some of the subscriptions which I can see when running Get-AzSubscription were missing when I ran the below: (Get-AzContext).Account.ExtendedProperties.Subscriptions So, the trick is to set the PSDefaultParameterValues for the Search-AzGraph cmdl
