Different Results with Powershel v2 and v3

hope can me determine why there difference in data between v2 , v3 of powershell. development on laptop has version 3 installed, script executed on server has version 2 installed.

#create directory searcher object , set it's porperties    $searcher = new-object directoryservices.directorysearcher    # (!useraccountcontrol:1.2.840.113556.1.4.803:=2) - filters out disabled accounts    $searcher.filter = '(&(objectcategory=person)(objectclass=user)(!samaccountname=its-*)(!useraccountcontrol:1.2.840.113556.1.4.803:=2))'    $searcher.pagesize = 5    $searcher.searchroot = "ldap://ou=district offices,dc=mydomain,dc=com"        #load following properties    $params = @("samaccountname","sn","givenname","mail","physicaldeliveryofficename","department","title","manager","distinguishedname")        foreach($param in $params)    {      $searcher.propertiestoload.add($param) | out-null    }    try    {      $found = $searcher.findall()  	$found | foreach-object {  	  if (($_.properties["distinguishedname"] -notlike "*,ou=generic user accounts*") -and ($_.properties["title"] -notlike "*consultant*") `  	    -and ($_.properties["title"] -notlike "*commissioner*") -and ($_.properties["title"] -notlike "*security guard*") `  		-and ($_.properties["title"] -notlike "*osc*") -and ($_.properties["title"] -notlike "*dcc*temp*") -and ($_.properties["samaccountname"] -ne "tbjohn") `  		-and (($_.properties["mail"] -ne "")))  	  {  	    $filtered += $_  	  }  	}    }

running script on machine produces data user looking for. when run on server, there users in data file should not be. in filter statement if change

-and (($_.properties["mail"] -ne "")))    #to    -and (($_.properties["mail"] -ne $null)))

users removed, other users included , haven't figured out why yet. why there difference, above script? think should work in version not true.

don't retire technet

try usinga simple , straighforward method. 

$searcher=[adsisearcher]'(&(objectcategory=person)(objectclass=user)(mail=*)(!samaccountname=its-*)(!useraccountcontrol:1.2.840.113556.1.4.803:=2))' $searcher.pagesize=500 $searcher.searchroot='ldap://ou=district offices,dc=mydomain,dc=com' $props=@("samaccountname","sn","givenname","mail","physicaldeliveryofficename","department","title","manager","distinguishedname") $searcher.findall() |      where-object{ 	    $_.properties['distinguishedname'][0] -notmatch ',ou=generic user accounts'         -and $_.properties["title"][0] -notmatch 'consultant|commissioner|security guard|osc|dcc.*temp'         -and $_.properties["samaccountname"][0] -ne 'tbjohn'     } 

notice uses less code , easier read.  put mail filter in search filter. (mail=*) - says include objects mail address not blank or null.   executes ont eh ad server , not on client powerhellll versiosn not behave differently.
