French translation of email encryption notification text

The email encryption notification text cannot be fully translated or modified. Some headers are available for translations or changes, but the rest of the notification text cannot be changed, so the notifications cannot be fully in French. Setting Admin Center → Markup Settings, Default Language for Banners & User-Facing Landing Pages had no effect on the email encryption section. Fix this issue ASAP so the entire text of the email encryption notifications can be translated. The request comes from Cosimo Berlingieri of RDP Consultants Inc.
