I need delivery cost excluded tax in email confirmation. I made changes:

1. in email translation order_conf I put total_shipping_tax_excl



2. 
   

   I made override in /override/classes/order/OrderHistory.php
   
   
   

   
   

   class OrderHistory extends OrderHistoryCore
    
    public function sendEmail($order, $template_vars = false)
    
    $data = array(
    'total_shipping_tax_excl' => Tools::displayPrice($order->total_shipping_tax_excl, $this->context->currency, false)
    );
    //die (print_r($data,true)); 
    if ($template_vars) 
    $data = array_merge($data, $template_vars);
    
   
    return parent::sendEmail($order, $data);
    
   
   

   
   

Override works - if I make die (print_r($data,true)); I can see that proper value is in total_shipping_tax_excl key. Email translation works - I see new string. But when email is sent then I have just total_shipping_tax_excl string.

What am I missing?

I was also editing the email template for Order Confirmation. You need to edit PaymentModule.php for it to work. You can also set the email subject directly from this file.

Around line 756

// Send an e-mail to customer (one order = one email)
if ($id_order_state != Configuration::get('PS_OS_ERROR') && $id_order_state != Configuration::get('PS_OS_CANCELED') && $this->context->customer->id) {
 $invoice = new Address((int)$order->id_address_invoice);
 $delivery = new Address((int)$order->id_address_delivery);

Enthu was right. First problem was that confirmation email is generated in classes/PaymentModule.php not in /classes/order/OrderHistory.php .
Solution is to override original file or wait. I made pull request: https://github.com/PrestaShop/PrestaShop/issues/11396 and chage was accepted so total_shipping_tax_excl and total_shipping_tax_incl will be in 1.7.6
