Dynamic Group for New Computers

Is it possible to create a MEM Dynamic group that only has new computers. For example, computers that first came online in the last 24 hours or 7 days?

Hello @jaybird283

Based on your requirement we need to use the registrationTime property, however this property is not yet available for use when creating membership rule for devices.

To achieve this you may create a Powershell script to add devices based on registrationtime. Please find below a sample script which compares the Azure AD Device RegistrationDateTime with DateTime value you supply and would add it to specified Azure AD Group.

Connect-MgGraph -Scope Device.Read.All
Select-MgProfile beta
Connect-AzureAD
$Date = Read-Host -Prompt "Enter the Date and Time in Format mm/dd/yyyy hh/mm/ss"
$GroupObjectID= Read-Host -Prompt "Enter Group Object ID in which you want to add the new devices registered to Azure AD Tenant post $Date"
$GroupName = Get-AzureADGroup -ObjectId $GroupObjectID | Select-Object -ExpandProperty DisplayName
Write-Host "Group you selected is $GroupName"
$Data = Get-MgDevice | Select-Object DisplayName,RegistrationDateTime,ID
ForEach ($line in $Data)
{
If ($line.RegistrationDateTime -ge "$Date")
{
Add-AzureADGroupMember -ObjectId $GroupObjectID -RefObjectId $line.Id -Debug
$ToPrint = $line.DisplayName
Write-Host "Added Device with Name $ToPrint to Azure AD Group with Name $GroupName" -ForegroundColor Green
}
}

Sample output:

Hi @jaybird283
Just checking in to see if the above script helped in adding the required computers to a group.
