- · Outlook : nouvelle option d'interface, messages épinglés, répétition, liste de messages sur deux lignes, glisser-déposer vers le calendrier.
- · Word : commentaires modernes, mode focus, co-édition native sur les fichiers locaux, vérificateur d'accessibilité entièrement revu.
- · PowerPoint : suggestions Concepteur, Cameo (insérer une webcam dans les diapositives), enregistrement de narration avec prompteur.
- · Dans toute la suite : peaufinage du mode sombre, composants Loop, améliorations de l'encre numérique.

Questions fréquentes
- Les deux versions peuvent-elles coexister sur un même PC ?
- Officiellement non — les programmes d'installation d'une version désinstallent l'autre. Utilisez l'outil de déploiement Office avec des indicateurs côte à côte uniquement si vous en comprenez les risques.
- Les fichiers .docx et .xlsx s'échangent-ils sans problème ?
- Oui. Le format de fichier est identique. Les fonctionnalités propres à 2024 ne s'affichent simplement pas dans 2021, mais les données sont préservées.
