How to find user in active directory with missing or empty attribute

You can use the normal "Get-ADUser" cmdlet for figuring out the users with missing or empty attribute:

Get-ADUser -Filter {-not (employeeid -like "*") }

The above command will return all objects that have the property empty.

using $null to match the filter criteria will result in the following error:
====================================================================
Get-ADUser : The search filter cannot be recognized
