The email body begins"Further to my colleagues recent telephone call, the purpose of this email is to explain that Microsoft would like to engage with your organization for the purpose of a License Verification process. This process is designed to review the Microsoft software you have deployed, comparing that to your corresponding license documentation. We will also draw your attention to some key licensing topics and benefits such as the Office 365 information sheet attached. It highlights the risks of unknowingly using non-genuine Office software and the benefits of ‘going genuine’ with Office 365 via the cloud. "
