Azure B2C Federated user login - Missing email and UPN

robcool 91 Reputation points


I'm using B2C federation with external AAD. The user doesnt have any email address in external Azure AD but has UPN value.
However, in B2C once the user logs it does create a user profile but with empty fields for userPrincipalName and email. Moreover, the block sign-in is also set to "Yes".

Any pointers on how this can be resolved ?
