[ActiveDir] problem changing "employeeID" attribute value

[Thommes, Michael M.]

For an AD user account, we normally populate the attribute “employeeID” with a value.  Circumstances surrounding some accounts requires me to “unpopulate” this value.  In ADSIEdit, however, when I go to this Unicode String valued attribute with the Edit function, I can delete the value but when I go to save it, I get “The parameter is incorrect.”  An unpopulated normal value shows “<not set>” (without the quotes).  Is it possible I should type in “<not set> instead of just trying to delete the value?  It just doesn’t seem right.  What am I doing wrong?  Any help is appreciated!   TIA!
