Get-MgApplicationOwnerCount

What is Get-MgApplicationOwnerCount?

Get-MgApplicationOwnerCount is a Microsoft Graph PowerShell cmdlet that returns the number of owners assigned to a specific Azure AD (Entra ID) application. Instead of listing owners one by one, it gives you a quick numeric count.

Why Use Get-MgApplicationOwnerCount?

This cmdlet is super handy for automation and governance. With one line, you can:

• Audit apps to ensure every application has at least one responsible owner.
• Flag risky apps with zero owners (common in legacy or abandoned registrations).
• Build compliance scripts that track owner counts across hundreds of apps without exporting large datasets.
• Combine the count with filters to validate ownership rules in bulk.

Prerequisites

Before using the cmdlet, connect to Microsoft Graph with the right permissions:

• Install the module (if needed):
  

  Install-Module Microsoft.Graph -Scope CurrentUser

• Connect with an app/owner read scope (typically):
  

  Connect-MgGraph -Scopes "Application.Read.All"

Also note: -ConsistencyLevel "Eventual" is required for count and advanced queries in Graph PowerShell.

How to use Get-MgApplicationOwnerCount?

Basic syntax (count requires consistency level):

Get-MgApplicationOwnerCount -ApplicationId <String> -ConsistencyLevel <String>

You pass the ApplicationId of the app registration, and Graph returns the number of owners. Optionally, use -Filter to count owners matching a specific condition.

Get-MgApplicationOwnerCount Examples

• Example 1: Get the Total Count of Owners for an Application

Get-MgApplicationOwnerCount -ApplicationId "12345678-90ab-cdef-1234-567890abcdef" -ConsistencyLevel "Eventual"

This returns a single number showing how many owners are tagged on that application.

• Example 2: Filter Application Owner Count By Application Owner Display Name

Get-MgApplicationOwnerCount -ApplicationId "12345678-90ab-cdef-1234-567890abcdef" -ConsistencyLevel "Eventual" -Filter "displayName eq 'John Doe'"

This counts only the owners whose display name matches John Doe, useful for verifying specific ownership assignments.
