How to Delete Old Emails in MS Exchange Using EWS

Background

I work within a corporate environment that manages its own Microsoft Exchange Server. I am also on a development team and receive thousands of automated email messages per day from various services that run across multiple servers. I started out creating rules for these emails in MS Outlook that sorted them into folders based on the service that generated them. I would go in once a day and clean out the folders.
