.TITLE
    Unassigned Policies Monitor

.SYNOPSIS
    Identify and report on all unassigned policies in Microsoft Intune.

.DESCRIPTION
    This script connects to Microsoft Graph and retrieves all device configuration policies
    configured in Intune, then checks which policies have no assignments to users, groups,
    or devices. Unassigned policies represent potential configuration drift, unused resources,
    or incomplete policy deployment. The script generates detailed reports in CSV format,
    highlighting unassigned policies with creation dates, policy types, and recommendations.
    This helps administrators maintain clean policy governance and identify policies that
    may need assignment or removal.

.VERSION
    1.4

.CHANGELOG
    1.4 - Added Azure Automation contract validation, portal-safe boolean parameters, beta Graph endpoints, and terminating paging errors
    1.3 - Azure Automation now records script progress, outcomes, and summaries in job history
    1.2 - Added a small delay between per-policy assignment checks to respect rate limits; policy list queries now select only needed fields; output directory is created automatically before the CSV export; pagination helper keeps single-item results as arrays
    1.1 - Local runs now use MgGraphCommunity for WAM-free interactive sign-in (auto-installed if missing)
    1.0 - Initial release

.LASTUPDATE
    2026-07-30

.EXAMPLE
    .\check-unassigned-policies.ps1
    Generates a report of all unassigned policies

.EXAMPLE
    .\check-unassigned-policies.ps1 -OutputPath "C:\Reports" -IncludeDetails "true"
    Generates a detailed report and saves to specified directory

.EXAMPLE
    .\check-unassigned-policies.ps1 -CreatedWithinDays 7
    Generates report for policies created in the last 7 days

.NOTES
    - Requires Microsoft.Graph.Authentication module: Install-Module Microsoft.Graph.Authentication
    - Requires appropriate permissions in Entra ID
    - Checks all policy types: Device Configuration, Settings Catalog, Administrative Templates
    - Unassigned policies may indicate incomplete deployment or unused configurations
    - Regular monitoring helps maintain policy governance and compliance
    - Consider removing or assigning policies that have been unassigned for extended periods
    - Local interactive sign-in uses the MgGraphCommunity module to avoid the Graph SDK's mandatory WAM broker on Windows
