Hi @GrantBradley,


As @Ethan Stern said, device cleanup rules are a great way of getting rid of stale devices from Intune and devices which has been unenrolled are automatically deleted from Intune.


Another way of deleting stale devices is via Intune PowerShell SDK. Before using this you have to install the module, 

Install-Module -Name Microsoft.Graph.Intune
Here is a simple example of removing devices which has not synced for 60 days:
PS C:\Windows\system32> $device = Get-IntuneManagedDevice -Select lastSyncDateTime, id | Where {($_.lastSyncDateTime -lt (Get-Date).AddDays(-60))} | foreach {$}

PS C:\Windows\system32> ForEach-Object {Remove-IntuneManagedDevice -managedDeviceId $device}


To delete stale objects from AzureAD see this docs page:

Hi Guys 


thanks for the advise on the issues are they any other ways you know of bulk removing devices from azure i see i can remove it from intune via powershell or rule but are they anything for azure ad 





@GrantBradley  Hi Grant, there are some cmdlets for removing from Azure AD-


Is that what you were thinking of?

hi Ethan 


i am already aware of that currently it is handy for removing one device but i am looking to remove in bulk if that is possible as devices have built over time and had not been removed

Hi @GrantBradley,


You could do something like this in PowerShell to delete stale devices from AAD:


$dt = [datetime]’2018/12/12’

Get-MsolDevice -All -LogonTimeBefore $dt | select-object -Property DeviceId | foreach {$_.DeviceID} | foreach {$_.Guid} | Remove-MsolDevice -Force


This gets and deletes all devices with a timestamp older than specific date. You can see more information in the doc I provided earlier.

I needed to deleted all personal windows devices from Intune
I used the following command to get a list of all personally owned windows 10 devices.
Get-IntuneManagedDevice | Get-MSGraphAllPages | Out-GridView

Next I took the list of id's for the devices I needed and used the code below to delete them.


# List of device id's to delete
$ids = get-content "C:\temp\ManagedDeviceIDs.txt"

Foreach ($id in $ids)

Write-host " Deleting DeviceName: $id"
Remove-IntuneManagedDevice –managedDeviceId $id –Verbose –ErrorAction Stop

Pretty simple stuff. Took me forever to figure it out. Hope this helps someone.
