Learn how to get lastlogon timestamp for specific OU and export to CSV by using Powershell script.

A PowerShell solution using the AD module cmdlet:

Get-ADUser -Filter * -SearchBase "ou=users,dc=contoso,dc=local" -ResultPageSize 0 -Prop CN,lastLogonTimestamp | Select CN,lastLogonTimestamp | Export-CSV -NoType last.csv

If you want get a date:

Get-ADUser -Filter * -SearchBase "ou=users,dc=contoso,dc=local" -ResultPageSize 0 -Prop CN,lastLogonTimestamp | Select CN,@{n="lastLogonDate";e={[datetime]::FromFileTime($_.lastLogonTimestamp)}} | Export-CSV -NoType last.csv

Below Command works if you want to leverage Quest’s cmdlets:

$OutFile = 'C:\MyExportFile.csv' # your output file$MyOU = 'OU=A,OU=B,OU=C,DC=ChildDomain,DC=ParentDomain,DC=com' # DNGet-QADUser -Searchroot $MyOU | foreach {Add-Content -path $OutFile "$($_.SamAccountName),$($_.LastLogonTimestamp)"}

This will do the same without any extra cmdlets:

$as = [adsisearcher]"(&(objectClass=person)(objectCategory=user))" $as.PropertiesToLoad.Add('cn')$as.PropertiesToLoad.Add('lastlogonTimeStamp')$as.PageSize = 200$as.FindAll() | ForEach-Object {    $props = @{ 'CN' = ($_.properties.item('cn') | Out-String).Trim()                'LastLogonTimeStamp' = ([datetime]::FromFiletime(($_.properties.item('lastlogonTimeStamp') | Out-String).Trim())) }    New-Object psObject -Property $props    } | Export-Csv 'Lastlogontimestamp.csv' -NoTypeInformation
