Processus dans Microsoft 365 pour configurer des applications Office, entrer des clés de produit et activer des licences.
Dear Astrid BOUGOUIN,
Thank you for your reply.
- May I know the version of your Word application?
Also, try pressing Ctrl + F1 and see if you can pin the ribbon.
Try to repair office by following below option and see you get the same issue.
I appreciate your cooperation and understanding.
Sincerely,
