Do the primary email address of user need to be unique?

@Lijia, thanks for your return.

Can you specify what kind of conflits ?

In fact, we are preparing to migrate our authentification to okta. So we need examiner anything
as detailed as possible. So could you confirm :

  • Okta enforce uniqueness for all primary email addresses, but it’s possible to disable this (by changing le profil mapping) technically ?
  • The notification could be sent to the second email (Error while creating multiple users with same email - Unique username - #4 by erik), could you specify where can i make this in the console ? cause i do find by now (l’ve just an admin accout, not a super admin in my org).

Thaks by advance.

Br,
