  • On the new page, click "Exchange".


  • Depending on the type of email you are trying to connect you'll be met with one of two sign in prompts:
    • For a generic address:
      •  select "More choices" 
      • Click "Use a different account"
      • Type your userid into the field with "nexus\" before your userid. For example, "nexus\"
    • For a personal account:
      • Enter your password in the password field.
      • Click "remember my credentials".
      • Press "OK".


  • If you wish to add other emails, enter in another address under "Add another email address" and click "Next".
