Force Intune Wipe With PowerShell: A Step-by-Step Guide

Table of Contents :

When managing a fleet of devices in an enterprise environment, security is of utmost importance. One critical aspect of device management is ensuring that lost or stolen devices can be wiped remotely to protect sensitive information. Microsoft Intune is a powerful tool for managing and securing devices, but sometimes, you may need to force an Intune wipe using PowerShell. In this guide, we'll walk you through the steps to perform an Intune wipe using PowerShell, ensuring your devices are secure. 💻🔒

Understanding Intune Wipe

Before we dive into the steps, it's essential to understand what an Intune wipe entails. An Intune wipe can be classified into two types:

  • Selective Wipe: This removes only the corporate data from a device while leaving personal data intact. It's useful for BYOD (Bring Your Own Device) scenarios.
  • Full Wipe: This erases all data from the device, including personal and corporate data. It’s used when a device is lost or when an employee leaves the organization.

Why Use PowerShell for Wiping Devices?

Using PowerShell to perform an Intune wipe offers several advantages:

  • Automation: You can automate the wipe process for multiple devices at once, saving time and effort.
  • Customization: You can tailor scripts to meet specific organizational needs, such as logging or notifications.
  • Integration: PowerShell integrates well with other Microsoft services, making it a versatile tool for IT administrators.

Prerequisites

Before we proceed with the wipe process, ensure you have the following prerequisites in place:

  1. Administrator Rights: You need to have admin privileges on the Microsoft Intune tenant.
  2. PowerShell Module: Make sure you have the necessary PowerShell modules installed. You can install the Microsoft.Graph.Intune module to interact with Intune APIs.
  3. Device Management: The devices you want to wipe must be enrolled in Microsoft Intune.

Installing PowerShell Module

To manage Intune using PowerShell, you will need to install the Microsoft.Graph module. Open PowerShell as an administrator and run the following command:

Install-Module Microsoft.Graph -Scope CurrentUser

Accept any prompts that appear during the installation process.

Step-by-Step Guide to Force Intune Wipe with PowerShell

Now that we have everything set up, let's go through the steps to perform an Intune wipe using PowerShell.

Step 1: Connect to Microsoft Graph

The first step is to connect to Microsoft Graph. Use the following command:

Connect-MgGraph -Scopes "DeviceManagement.Service"

A prompt will appear asking you to log in with your administrator credentials. Ensure you have the appropriate permissions to manage devices.

Step 2: Retrieve Device Information

Next, you need to identify the device you want to wipe. Use the following command to list all devices managed by Intune:

Get-MgDeviceManagementManagedDevice | Select-Object Id, DeviceName, UserPrincipalName

This command will display a list of devices along with their unique IDs, device names, and user principal names.

Step 3: Select the Device to Wipe

Once you have the list of devices, identify the device you want to wipe. You will need the device ID for the next step. Make a note of the device ID.

Step 4: Perform the Wipe

To initiate a wipe on the selected device, use the following command:

Invoke-MgDeviceManagementManagedDeviceWipe -ManagedDeviceId "DEVICE_ID" -KeepEnrollmentData $false -WipeAfterInactiveDuration $null -RestoreFactoryDefaults $true

Replace "DEVICE_ID" with the actual ID of the device you noted earlier.

Wipe Command Breakdown

The parameters used in the wipe command are:

  • ManagedDeviceId: The unique ID of the device you want to wipe.
  • KeepEnrollmentData: Setting this to $false means that the enrollment data will be wiped along with the device.
  • WipeAfterInactiveDuration: This can be set to specify a period after which the wipe should occur if the device remains inactive. Setting it to $null means that the wipe happens immediately.
  • RestoreFactoryDefaults: Setting this to $true ensures that the device is returned to its factory settings after the wipe.

Step 5: Confirm the Wipe

After executing the wipe command, you should receive a confirmation message in PowerShell. You can also check the status of the wipe by running the following command:

Get-MgDeviceManagementManagedDevice -ManagedDeviceId "DEVICE_ID"

This will provide you with the current status of the device, including whether the wipe command has been processed.

Important Notes

"Always double-check the device ID before performing a wipe. Wiping the wrong device can lead to data loss and operational issues."

Best Practices for Wiping Devices

When using PowerShell to wipe devices, it’s crucial to follow best practices to avoid potential issues:

Regularly Audit Devices

Periodically review the list of devices enrolled in Intune to ensure that you have the most up-to-date information. Regular audits help prevent accidental wipes.

Implement Role-Based Access Control (RBAC)

Limit the number of users who have access to the wipe functionality by using role-based access control. This minimizes the risk of unauthorized wipes.

Test in a Controlled Environment

Before executing wipes on production devices, consider testing your PowerShell commands in a controlled environment. This helps to confirm that your scripts work as expected.

Maintain an Inventory

Keep an inventory of all devices along with their users. This documentation can be invaluable when troubleshooting or deciding which devices to wipe.

Troubleshooting Common Issues

While executing a wipe command, you may encounter some issues. Here are a few common problems and solutions:

Issue: Access Denied

If you receive an "Access Denied" error, double-check your permissions. Ensure that your account has the necessary administrative rights in Intune.

Issue: Device Not Found

If you receive a "Device Not Found" error, confirm that the device ID you entered is correct and that the device is enrolled in Intune.

Issue: Wipe Command Fails

If the wipe command fails, check for connectivity issues or service outages with Microsoft Intune or Microsoft Graph. Ensure that your PowerShell session is correctly connected to Microsoft Graph.

Monitoring Wipe Commands

After initiating a wipe, it's crucial to monitor the status of the wipe command. You can do this by continuously querying the device status or checking the Intune admin center for updates.

Using PowerShell to Monitor Status

You can set up a loop in PowerShell to periodically check the status of the wipe command. Here’s a simple example:

$deviceId = "YOUR_DEVICE_ID"
do {
    $status = Get-MgDeviceManagementManagedDevice -ManagedDeviceId $deviceId
    Write-Host "Current Status: $($status.ManagementState)"
    Start-Sleep -Seconds 30
} while ($status.ManagementState -ne "wipePending" -and $status.ManagementState -ne "wiped")

This script will check the status every 30 seconds until the device is either in a "wipePending" state or has been "wiped."

Conclusion

In today's digital landscape, ensuring the security of corporate devices is critical. Using PowerShell to force an Intune wipe provides IT administrators with a powerful method to secure devices, whether they are lost, stolen, or no longer in use. By following the steps outlined in this guide and adhering to best practices, you can efficiently manage device security in your organization. Remember to regularly review your device management policies and keep your PowerShell scripts updated to reflect any changes in your organization’s needs. With the right tools and knowledge, you can effectively protect your enterprise’s sensitive information. 🛡️✨
