We have setup Azure B2C and it's working great - authentication is working with the portal and a contact is created and external identity created for the contact on the portal. Problem is that if the contact exists (which 99% times it does for the implementation) with the same email address, it doesn't merge the external, but rather refuses to create, and requires a new email and a new contact is created. That's not going to work.
I've tried adding:

I have the same question (0)There are two requirements to make this work once configured:
1. You must be using the field emailaddress1 on contact to represent the email address (it cannot be mapped to a secondary email such as emailaddress2)
2. The email *must* be unique. If there are more than one other record with the same email, the portal will create a third instead of selecting at random one of the two existing ones.
And just to check - are you mapping the inbound email claim from B2C to the email address (RegistrationClaimsMapping)?
Thanks,
