Read msg. files with multiple msg email file as attachment

Hi everyone,

i've got a problem with email sent to a process model with multiple nested .msg attachment. I want to extract the last nested email attached to the incoming email, but the received message node doesn't process the .msg file. it simply download all the other files (pdf, .xml...) without reading any information of this series of the nested .msg attached emails. I've used the striphtml(msg!properties.Attachments) function in the received message node configured to receive incoming email, as shown in the pitcure below. I don't use the read msg plug-in because i have to download the .msg file as attachment from the incoming email, so it's useless for my process. 

Thank you all
