Get-MgUserAppRoleAssignmentCount: Graph PowerShell Cmdlet

In Microsoft Entra ID, users can be assigned application roles (app roles) to access enterprise applications. While listing every assignment is useful, many scenarios only require a quick count of how many app role assignments a user has.

The Get-MgUserAppRoleAssignmentCount cmdlet is designed for this purpose—it returns a numeric count of app role assignments for a given user, making it lightweight and ideal for audits, reporting, and automation.

i) Cmdlet Syntax

Get-MgUserAppRoleAssignmentCount -UserId <String> [-ConsistencyLevel <String>]

Key Parameter:

• -UserId: Specifies the user whose app role assignments you want to count.
  You can provide a User Principal Name (UPN) or the Object ID.
• -ConsistencyLevel: Required for advanced queries. Typically set to eventual.

ii) Usage Examples

Example 1: Providing UserId when prompted by the console

Get-MgUserAppRoleAssignmentCount

Explanation:
When the cmdlet is run without explicitly providing -UserId, the console prompts you to enter the user identifier. After input, it returns the total number of app role assignments for that user.

Example 2: Directly passing UserId with ConsistencyLevel header

Get-MgUserAppRoleAssignmentCount ` -UserId tks@w4l0s.onmicrosoft.com ` -ConsistencyLevel Eventual

Explanation:
Returns the total count of app role assignments for the specified user, explicitly passing the user principal name and setting the required consistency level to ensure the query succeeds.

Example 3: Exporting the results to CSV

Get-MgUserAppRoleAssignmentCount ` -UserId tks@w4l0s.onmicrosoft.com ` -ConsistencyLevel Eventual | Export-CSV "d:/approleassignments2.csv"

Explanation:
Exports the numeric result to a CSV file. This is useful when collecting counts across users for reporting or audit documentation.

iii) Cmdlet Tips

• This cmdlet returns only a number, not detailed assignment objects.
  Use Get-MgUserAppRoleAssignment if you need assignment details.
• Always use -ConsistencyLevel Eventual to avoid query failures.
• Supports both UPN and Object ID for the -UserId parameter.
• Ideal for large tenants, as counting is significantly faster than enumerating all assignments.

iv) Possible Errors & Solutions

Error / Message	Cause	Solution
Request_UnsupportedQuery	Missing consistency level	Re-run the command with -ConsistencyLevel Eventual.
Authorization_RequestDenied	Insufficient permissions	Ensure AppRoleAssignment.Read.All or Directory.Read.All is granted.
ResourceNotFound	Invalid UserId	Verify the user’s UPN or object ID.
Output is 0 unexpectedly	User has no direct app role assignments	Confirm whether access is granted via group-based assignments instead.
Cmdlet not recognized	Microsoft.Graph module missing	Install or update using Install-Module Microsoft.Graph.

v) Conclusion

The Get-MgUserAppRoleAssignmentCount cmdlet provides a fast and efficient way to determine how many application roles are assigned to a user in Microsoft Entra ID. By returning only a count, it reduces overhead and is well suited for audits, governance checks, and automation workflows where performance and simplicity matter.
