Translate suffixe UPN from French to English

– The part of the user principal name (UPN) to the right of the @ character. The default UPN suffix for a user account is the DNS domain name of the domain that contains the user account. Alternative UPN suffixes may be added to simplify administration and user logon processes by providing a single UPN suffix for all users. The UPN suffix is only used within the Active Directory forest, and it is not required to be a valid DNS domain name. ¹
