New Windows 10 Image: Outlook 2013 not connecting to Microsoft Exchange Servers

    Question

  • We are rolling out Windows 10 within our enterprise environment, I have logged into one of our domain joined machines with the new win10 image deployed on it. This is our test box. I logged on with my regular user credentials, opened outlook then received the following error pictured above. The outlook web app works fine. I get the same error on multiple test boxes with windows 10. These boxes are currently in a test OU within AD but under our domain hierarchy. Everything else seems to be working fine. Deleting profiles does not work, all who login to these boxes have the same issue. Importing the Users Shell registry key from a working profile does not work either. Any ideas?

    ERROR: "The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action."
