AzureADDeviceCleanup PowerShell script helps to manage the stale devices in Azure AD in an efficient way by giving different options to deal with stale devices in Azure AD.
- To check the stale devices in Azure AD.
- To generate a powerful Excel report with the stale/disabled/deleted devices.
- To automate Azure AD device cleanup procedure by running it in a scheduled task.
- Can be used to disable the stale devices for a period of time, then clean them safely.
- To show the result on Grid View or/and Excel, so you can easily search in the result.
- Verifies the stale devices as per the entered threshold days.
- Disables the stale devices as per the entered threshold days.
- Verifies the stale disabled devices as per the entered threshold days.
- Cleans the stale devices from Azure AD as per the entered threshold days.
- Cleans the stale disabled devices only from Azure AD as per the entered threshold days
- Checks if ‘AzureAd‘ module is installed and updated. If not, it takes case of this.
- Checks if ‘ImportExcel‘ module is installed. If not, it installs and imports it.
Note
It is recommended to disable the stale devices for a grace period of time before deleting them from AAD safely, as you can not recover the deleted devices.
Using AzureADDeviceCleanup PowerShell script, you can automate Azure AD devices cleanup using schedule task as the following (ThresholdDays value can be changed as per the company's policy):
-
Disable all stale devices since 60 days using the PowerShell command:
AzureADDeviceCleanup.ps1 -ThresholdDays 60 -DisableDevices -SavedCreds -
Then, Delete the stale disabled devices since 90 days using the PowerShell command:
AzureADDeviceCleanup.ps1 -ThresholdDays 90 -CleanDisabledDevices -SavedCreds

It is not advisable to immediately delete a device that appears to be stale because you can't undo a deletion in the case of false positives. As a best practice, disable a device for a grace period before deleting it. In your policy, define a timeframe to disable a device before deleting it.
-
When configured, BitLocker keys for Windows 10 devices are stored on the device object in Azure AD. If you delete a stale device, you also delete the BitLocker keys that are stored on the device. You should determine whether your cleanup policy aligns with the actual lifecycle of your device before deleting a stale device.

.PARAMETER
ThresholdDays
Specifies the period of the last login.
Note: The default value is 180 days if this parameter is not configured.
.PARAMETER
Verify
Verifies the affected devices that will be deleted when running the PowerShell with 'CleanDevices' parameter.
.PARAMETER
VerifyDisabledDevices
Verifies disabled devices that will be deleted when running the PowerShell with 'CleanDisabledDevices' parameter.
.PARAMETER
DisableDevices
Disables the stale devices as per the configured threshold.
.PARAMETER
CleanDisabledDevices
Removes the stale disabled devices as per the configured threshold.
.PARAMETER
CleanDevices
Removed the stale devices as per the configured threshold.
.PARAMETER
OnScreenReport
Displays The health check result on PowerShell screen.
.PARAMETER
SavedCreds
Uses the saved credentials option to connect to MSOnline.
You can use any normal CLOUD only user who is having read permission to verify the devices.
But you have to use a global admin when using clean parameters.

.EXAMPLE
.\AzureADDeviceCleanup.ps1 -VerifyDisabledDevices -ThresholdDays <Number of Days> -DisableDevices
Disables the stale devices as per the entered threshold days.
.EXAMPLE
.\AzureADDeviceCleanup.ps1 -ThresholdDays <Number of Day> -CleanDevices -SavedCreds
