such does not make logical sense, TBH. BUT you could easily modify the script. look at the
$users = get-aduser ...
near line 42 and modify as needed. look at the area that calculates DaysToExpire, then possibly modify theswitch
statement coptions near line 113.i have another script that we never put into production that would tell NEW accounts they needed to change there initial password. maybe this is something you would like. please see https://gist.github.com/meoso/f17307bb852930960c1c7fb2d55e967f and review lines 48 & 49 for potential modification. again the powershell
$users = get-aduser ...
is how you filter users. see cmdlet get-aduser.
