Dear de MONTPELLIER Mélanie,
Good day! Thank you for your reply to Microsoft Community. We are happy to help you.
Can you confirm when you get this error? (Nous n’avons pas obtenir le lien. Veuillez réessayer plus) when the user accesses the shared link he will get this error or when you try to create the share link to the user you get this error?
And also try to crate a group and ad users to it and try to add the group to the list and test you get the same error.
And also try self-diagnostic you can refer to this article how to do self-diagnostic
Self-help diagnostics for SharePoint Online and OneDrive
.
Your understanding and patience will be highly appreciated.
If there is any misunderstanding, please feel free to correct me.
Have a nice day!
Best regards,
