One of the coolest Active Directory features is the recycle bin which gives you the ability to recover deleted Active Directory objects. Your forest functional level must be at least 2008 R2. When you delete an object, you can restore it through the Active Directory Administrative Center.
Sometimes, you may want to permanently delete one item in this recycling bin. There is no way to perform this task using the GUI, so you must use Windows PowerShell.
First, check if the deleted object is still in the recycle bin:
PS > Get-ADObject -Filter 'isDeleted -eq $True -and Name -like "*username*"' -IncludeDeletedObjects
Depending the output, you can permanently remove the object using the following:
PS > Get-ADObject -Filter 'isDeleted -eq $True -and Name -like "*username*"' -IncludeDeletedObjects | Remove-ADObject
You can add -Confirm:$false if you don’t want to confirm the deletion.
