O365 ProPlus weird activation error

Hello everybody !

Sorry for the bing traduction...

I've got a problem with my office365 2016 proplus.

On srv2012R2/RDP installation :

Since yesterday, all users of Office ProPlus (TSE installation with ODT) get the "votre abonnement a expiré (youre subscription expired)", and "La version d'office à laquelle vous êtes abonné n'est plus commercialisée. Ce produit ne dispose plus de licence (The version of Office you ave subscribed to is no longer marketed. This product no longer has a license)"

I reinstalled Office  (monthly option), but I still get this error.

Do you have an idea to resolve this ?

Best regards

Remy
