Magento 1.9.x trying to save $customer data => "Uncaught Mage_Customer_Exception: This customer email already exists"

Question

Magento 1.9.x trying to save $customer data => "Uncaught Mage_Customer_Exception: This customer email already exists"

We are looping thru all customers, updating data and saving

Only when saving a customer with an email that already exists: we see the error Uncaught Mage_Customer_Exception: This customer email already exists

Although when I check Magento the email does exist twice, but in different stores. So it should! save the customer, nothing is wrong

Question: how can we prevent this from happening?

We are looping data as follows

$customers = mage::getModel('customer/customer')->getCollection()
 ->addNameToSelect();
$cnt_me = 0;
foreach ($customers as $customer) {
 $data = array();
 $customer_id = $customer->getId();
 $customer_name = $customer->getName();
 $customer_email = $customer->getEmail();
 $orders = Mage::getModel('sales/order')->getCollection()
 ->addFieldToFilter('customer_id', $customer_id)
 ->addFieldToFilter('state', array('in' => Mage::getSingleton('sales/order_config')->getVisibleOnFrontStates()));
 foreach ($orders as $order) {
 foreach ($order->getAllItems() as $item) 

{

then later we do the following

if ($save) {
 $this->_dataSaveAllowed = true;
 $customer->save();
} else {
 continue;
}

• Sohel Rana: Did you check website id? or your settings is global for all store?

Answer 1

You need to do following things.

$store_Id = ''; // PASS STORE ID FOR WHICH YOU GET COLLECTION
$store = Mage::getModel('core/store')->load($store_Id);
$customers = Mage::getModel('customer/customer')->getCollection()
 ->addFieldToFilter('store_id',$store_Id)
 ->addNameToSelect();
foreach ($customers as $customer) 
{
 .........................
 $customer->setStore($store);
 $customer->save();
}

The solution is to : double (yes double) check if there is max 1 account per email per store.

In our case somehow customers were created with store is admin, but storeview is the same as a store where the user already existed.

So the solution was to clean the data and make absolutely certain there are no duplicate emails
