Bonjour,

We can’t log you in because of the following error.

ERROR_CREATING_USER: Duplicate Username.<br>The username already exists in this or another Salesforce organization. Usernames must be unique across all Salesforce organizations. To resolve, use a different username (it doesn't need to match the user's email address).
