# .TITLE Non-Compliant Devices with Reasons Report .SYNOPSIS Identify all non-compliant devices in Intune and the specific setting(s) that caused each failure. .DESCRIPTION This script connects to Microsoft Graph, retrieves every managed device whose compliance state is non-compliant (and optionally error / in grace period), then drills into each device's compliance policy states and the underlying setting states to surface the exact reason a device is non-compliant. For every failing setting it reports the owning policy, the setting name, the reported state, the current value, and any error code/description. Results are exported to both CSV (one row per failing setting) and a summary HTML report. .TAGS Compliance,Devices,Reporting .MINROLE Intune Administrator .PERMISSIONS DeviceManagementManagedDevices.Read.All,DeviceManagementConfiguration.Read.All .AUTHOR Ugur Koc .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 - Output directory is created automatically when missing; per-device and per-policy Graph calls are spaced with a short delay to reduce throttling; summary counts are wrapped in @() so single-result queries report accurate totals; progress bar output is suppressed in Azure Automation 1.1 - Local runs now use MgGraphCommunity for WAM-free interactive sign-in (auto-installed if missing); report auto-open failures no longer abort the script 1.0 - Initial release .LASTUPDATE 2026-07-30 .EXAMPLE .\get-noncompliant-devices-with-reasons.ps1 Reports all non-compliant devices and the settings that caused the failure .EXAMPLE .\get-noncompliant-devices-with-reasons.ps1 -ComplianceStates noncompliant,error,inGracePeriod Includes devices in error and grace-period states in addition to non-compliant ones .EXAMPLE .\get-noncompliant-devices-with-reasons.ps1 -OutputPath "C:\Reports" -OpenReport "true" Saves the reports to the specified directory and opens the HTML report when finished .NOTES - Requires Microsoft.Graph.Authentication module: Install-Module Microsoft.Graph.Authentication - Requires appropriate permissions in Entra ID - Uses the Microsoft Graph beta endpoint to retrieve setting-level compliance detail - The CSV contains one row per failing setting; a device with multiple reasons appears on multiple rows - Devices flagged non-compliant with no setting-level detail (e.g. recently enrolled or not yet evaluated) are reported with a placeholder reason so they are not silently dropped - Large tenants may take several minutes: the script makes additional Graph calls per device - Disclaimer: This script is provided AS IS without warranty of any kind. Use it at your own risk. - Local interactive sign-in uses the MgGraphCommunity module to avoid the Graph SDK's mandatory WAM broker on Windows #> [CmdletBinding()] param( [Parameter(Mandatory = $false, HelpMessage = "Compliance states to include in the report")] [ValidateSet("noncompliant", "error", "inGracePeriod", "conflict", "unknown")] [string[]]$ComplianceStates = @("noncompliant"), [Parameter(Mandatory = $false, HelpMessage = "Output directory for the reports")] [string]$OutputPath = ".", [Parameter(Mandatory = $false, HelpMessage = "Open the HTML report after generation")] [ValidateSet("true", "false", "1", "0", '$true', '$false')] [string]$OpenReport, [Parameter(Mandatory = $false, HelpMessage = "Force module installation without prompting")] [ValidateSet("true", "false", "1", "0", '$true', '$false')] [string]$ForceModuleInstall ) # Normalize the local module-install override for Azure Automation parameter binding. $forceModuleInstallRaw = [string]$ForceModuleInstall Remove-Variable -Name ForceModuleInstall if ([string]::IsNullOrWhiteSpace($forceModuleInstallRaw)) { $ForceModuleInstall = $false } elseif ($forceModuleInstallRaw.Trim().ToLowerInvariant() -in @("true", "1", '$true')) { $ForceModuleInstall = $true } elseif ($forceModuleInstallRaw.Trim().ToLowerInvariant() -in @("false", "0", '$false')) { $ForceModuleInstall = $false } else { throw "Parameter 'ForceModuleInstall' accepts only true, false, 1, 0, $true, or $false." } # Azure Automation supplies portal parameter values as strings.
