You use a lot of terms that could be taken more ways than one. Batch load from where to where? What is your definition of batch load?
What is reprocessing by Access? You want Access to verify the content of a pdf? I'd be surprised if you can do this since even what looks a pdf text document could actually be an image of a document.
If you're looking to have the file path loaded into a table from network folders, that's doable. To make a connection between that and something else in the database (e.g. customer) you'd need an identifier that could come from the path (such as the folder name or the last n characters of the file name for example). If you're looking for someone to write code that will grab the attachments from an email and dump them in the network via Access code, I suppose that's possible but not by me.
When reading your post I thought the last paragraph was going to sum up what needs to happen, but I'm afraid I don't understand the situation and goal any more so. That's because you state what you need to do in a way that portrays you understand the task but ask if it's possible. When you put it that way, I have no idea of what you need from us.
Sorry.
