iCloud Calendar with Outlook 2013/Exchange

Hi, first of all, I am a new user with iCloud and consider myself a novice when it comes to iTunes, iPhones and other Apple products. I have an iPhone 4S configured with a Shared Calendar with my wife, Windows 7 PC running iTunes 11.1.2.32, iCloud and Outlook 2013 connected to my Corporate Exchange server via VPN. In Outlook, I see a second Calendar called iCloud Archive which contains only older events from my Shared Calendar. I am not even sure how this got created in the first place? How do I get all of our newly added events to appear in Outlook? Note, I do not want my work calendar to appear in my iCloud Calendar, so I say "NO" when prompted to merge. Thank you in advance for any assistance you can provide.
