Currently, I use PowerUser 2018.
On importing eMail to PowerUser with add-on "Store Message" in MS Outlook, eMail attachments are stored inside of file "*.msg".
To see eMail attachments, we need to open the eMail with MS Outlook.
An other way to see eMail attachments directly with the the viewer inside the PowerUser is to store this as hybrids parts. But this operation must be done manualy.
Is it possible to foreseen in PowerWeb, the automation of the storage eMail attachments as hybrids parts with "Store Message" add-on in MS Outlook.
See in attachment file structur of eMail file with its Hybrid parts.
