Exchange forward / enabled

#Get users
$users = get-aduser -searchbase "OU=ou,OU=Hosted Exchange Customers,DC=DMZ,DC=local" | select samaccountname, name,enabled

#Loop through users to get info
foreach ($user in $users)
{

#Get the forwarding address on the mailbox
$fwd = get-mailbox -Identity $user.samaccountname | select (get-mailbox -Identity $user.samaccountname).forwardingaddress
if($fwd)
{

#Get the SMTP of the forwarding address if it exists
$PrimarySMTP =  (get-Recipient $fwd | select  PrimarySMTPAddress).PrimarySMTPAddress
}
else{$PrimarySMTP = ""}

#Create custom object to export CSV with all info.
    New-Object -TypeName PSCustomObject -Property @{
                User= $User.Name
                Enabled = $user.Enabled
                ForwardingAddress= $PrimarySMTP} >> "c:\Users\x\Desktop\forwards.csv"
    }

This fails on the -expand and is the reason I tried the above method.

#Get users
$users = get-aduser -searchbase "OU=ou,OU=Hosted Exchange Customers,DC=DMZ,DC=local" | select samaccountname, name,enabled

#Loop through users to get info
foreach ($user in $users)
{

#Get the forwarding address on the mailbox
$fwd = get-mailbox -Identity $user.samaccountname | select -expand ForwardingAddress
if($fwd)
{

#Get the SMTP of the forwarding address if it exists
$PrimarySMTP =  (get-Recipient $fwd | select  PrimarySMTPAddress).PrimarySMTPAddress
}
else{$PrimarySMTP = ""}

#Create custom object to export CSV with all info.
    New-Object -TypeName PSCustomObject -Property @{
                User= $User.Name
                Enabled = $user.Enabled
                ForwardingAddress= $PrimarySMTP} >> "c:\Users\x\Desktop\forwards.csv"
    }
