$report="c:\\ReportSvcMBXLastLogon.csv"
Clear-Content $report
add-content $report "Handle,MailboxDisplayName,LoggedOnUserAccount,LogonTime,ClientMode,ClientVersion,ServerName"

foreach ($usr in $user)
{
$identity= $usr.handle

$script=get-mailbox -identity $identity | select-object legacyExchangeDN,servername
if($error.count -gt 0){
$string ="User " + $identity  + " doesn't exist in AD"
add-content $report -VALUE $string
write-host "User " $identity "  doesn't exist in AD"
$error.clear()
}
else
{
foreach ($u in $script)
{

$legDN=$u.legacyExchangeDN
$serverEx=$u.servername

$lastL=get-wmiobject -class Exchange_logon  -Namespace "root\MicrosoftexchangeV2"  -Computer $serverEx -Filter "MailboxLegacyDN='$legDN'"|select-object  MailboxDisplayName,LoggedOnUserAccount,LogonTime,ClientMode,ClientVersion,ServerName
write-host $legDN

foreach ($2k3 in $lastL) {
              
               $displN=$2k3.MailboxDisplayName
               $LOnUser=$2k3.LoggedOnUserAccount
               if ($2k3.LogonTime -ne $null) {
                 $LOnTime=[System.Management.ManagementDateTimeConverter]::ToDateTime($2k3.LogonTime)
  }else{
   $LOnTime=$2k3.LogonTime
  }
               $cliMode=$2k3.ClientMode
