This email looks like it could be legitimate but upon closer inspection is a phishing attempt. Hovering over the link shows that the link goes to the secure-web.cisco.com site which helps protect you from malicious emails but also obfuscates links. If you click the link, the Cisco site will render it for you and you can see that it doesn't go to Microsoft or Purdue.
