signed email to cases on office365

[item]

Dear,
I have no problem with email to cases on office365. all work perfect but I have found a strange result :

I have received two email "signed" (Ce message contient une signature numérique qui n’a pas été vérifiée, car pour l’instant, votre navigateur ou votre plateforme ne prend pas en charge le contrôle S/MIME.)
As you can see in attachement, the two message have a special icon, and the two message have attachment.
On espocrm, these two message create 2 cases.. but I loose the attachement. (the two attachement are not on espocrm).
All the other email work fine, the only difference with other mail is the "signed" this is why I think the problem come with that.
The problem is not the size of attachement or not the kind is pdf.

Are any experiment this ?

Regards

Can i do that :
dump only data of mysql
install last version of espocrm
copy custom folder to new install
make a rebuild and clear cache
insert mysql data

Regards.

better is to upgrade crm from version to version. Some of updates have important modifications in database structure
