Summary0005030: Outlook 2016/2019 + S/MIME problem

Hi guys!
Mail sent from SOGO with a s/mime Actalis signature to Outlook shows that the Actalis signature is invalid.
Of course it is valid.
Mail between SOGO users or Outlook works well.
What could be causing this?

Does Outlook know the Actalis CA?

I added it manually. Nevertheless, Outlook 2019 still shows a warning that the signature is invalid.
In addition, it seems to me very uncomfortable. Indeed, in 99%, the recipient will not even be able to understand what he needs to do and simply will not open this email.
