How to Move Attachments from an Email to a Case in Dynamics CRM 2016

Hi,

I've created an "Automatic Case Creation Rules" to create case from incoming E-mails.But the attachments didn't move to the created case.

Any suggestions ?

i found in forums some solutions like : moving attachement from Email to the attachement that existe in note of the target Case.

So, to implement this solution i need to know witch plugin is fired when the case is created from the "Automatic Case Creation Rules' .

All suggestions are wellcome

thanks in advance.
