PayPal Express creating accounts with Duplicate Emails

[dadkind]

(This may be a duplicate post)
We activated PayPal option last weekend and sales have been good! But....

We are creating accounts with existing email addresses. Here is my scenario.
1. Existing customer NOT logged in shops and goes to ShoppingCart page.
2. Clicks the PayPal express button (still not logged in).
3. Goes to PayPal and pays for the order using the email he used to create his ASPDNSF account.
4. Response comes back from PayPal and order is created. But Account is also created as well.

Version: AspDotNetStorefront Multistore 9.1.0.1/9.1.0.0
GlobalSettings.AllowCustomerDuplicateEMailAddresse s = false;

Any ideas on how to match PayPal order with the existing account?

Though the account is created within ASPDNSF the IsRegistered value will be set to 0 this means that whilst the record exists within ASPDNSF no password is set. If you want to turn these into accounts you will need to change the IsRegistered feature to 1 and then assign a password.

Caution..if you do this ensure there is also a telephone number in the Phone field, if not then we found the customer is locked out.

It looks like there is a bug in the Gateway code. A simple one-line fix now allows us to "match up" returning emails with existing accounts.

(Caution: still in testing as I write this).
