Hello,
"Can I rename an email attachment before I save it into a Folder?
Or maybe to save the attachments into different folders for each email?"
No, there is no function for renaming attachments.
"In addition, is there any way to see the attachment in the Database as I am receiving it from the Sender? (e.g. Excel File or PDF File etc)"
No, GeniusConnect cannot visualize attachments (or any other data) stored in your database
