Mails illisible sous outlook 2003 windows 7

Bonjour,

J'ai un pb depuis que j'ai réinstallé mon ordinateur (windows 7 et outlook 2003) je reçois quelque mail dans un format illisible. Il s'agit toujours des même expéditeur.

Mon serveur de messagerie est free, et lorsque je regarde mes mails avec zimbra (juste avant de les récupérer dans outlook) ils sont tous lisibles.


Voici un exemple de mail :
