Inspection SSL Untrusted CA

Hello,

We have the deep inspection activated for the outcoming connexion. Microsoft has changed their certificat for the hostname europe.cp.wd.microsoft.com resently with an another CA and now I get the error "block-cert-untrusted" from the UTM.

So I think to resolve this issue I have to import manually the new chain for this CA in the fortigate ? where can I get the CA list that the fortigate already know ? Does the CA list are automatiquely updated from fortiguard ? 

Before I was on checkpoin and I had to import manually the CA cert.

Thank you for your answer

Regards,
