PowerShell - How to Download Email Attachments from Exchange Server

I have a big task and I don't know if this can be done through VBA.  Let me explain what I need to be done.

1.  I have several clients that I setup an email address through Exchange server (not my personal outlook inbox) with a user name and password.

2. Then I have several customers that sending email attachment for that particular client.  Let say one of the client’s name Troy Corporation and the email will be mailto:email address removed for privacy reasons

The customer’s name is: Daybreak Fast, FedEx Freight, R&L Carriers, and TRN Logistics.  All the customers are sending email attachment into Troy Corporation mailbox. Side Note: (sometimes I have different customer send the attached file. Let say this I have this week Mr. mailto:email address removed for privacy reasons and next week I have Mrs. mailto:email address removed for privacy reasons I need the program to check for both emails to see if one of them send me a file.

What I need is to do is login to mailbox (Troy Corporation) retrieve each email with the attached file for each customer, then download them to my network folder.  If I did not receive an attachment for any of the customer to send them a second request with a note on the body "we did not receive your file" something like that.

3. So, when I login for second time to retrieve the remaining attached file. But if I did receive the email attachment either on the first or the second attempt, the customer SHOULD NOT RECEIVE a second request because I did receive their file.

I do have more after all the files are download to my network folder.  But I want to know if this can be done through Power Shell.
