Script to save attachment from email

So I’m learning powershell right now and I’m trying to put a script together that saves a CSV file from an email to a network folder, and then reading that CSV file and piping a certain column to another script that I have done already.

I’ve written one script for the saving the attachment to a folder in VBS, but for some reason it isn’t working. That’s besides the point but it would be why I’m looking for a powershell solution.

Any help that anyone could provide would be awesome. Thanks in advance!
