Office 365: Configuring Mac Mail


Office 365 is a shared service across the university and health system. Documentation for this service will cover the needs of both Duke Health and University customers.


While this documentation is written for the latest release of Mac OS X, the directions can be applied to earlier releases including Mac OS 10.5 – 10.10. Be aware there are some minor and major differences (ex. iCal is called “Calendar” in earlier versions of Mac OS X). Major differences include the look of the dialog boxes. 

In some instances, it can take time for all components to be in place for configuring Mac Mail. In the interim, you can always access your mail by going to https://mail.duke.edu

  1. Open Mail, and then do one of the following:
    • If you’ve never set up any e-mail accounts using Mail, a new window will drop down. In the Choose a Mail account provider window, select Exchange and Continue.
    • If you’ve already created e-mail accounts using Mail, your client will open as normal. Go to the Mail menu and select Add Account. In the Choose a Mail account provider window, select Exchange and Continue.
  2. In the window that appears enter the following information:
    • In the Name box, enter your name.
    • In the Email Address box, enter your netid@duke.du. 
    • In the Password box, enter the password for your NetID, and then click Sign In

    The Mail program will use the information you entered in the previous step to try to set up your e-mail account automatically. 

  3. If the Mail program was able to set up your account, you can select the “apps” you want to set up for the Office 365 account including: 
    • Mail (the program you are configuring)
    • Contacts which connects to the Office 365 Global Address List (GAL) to the Address Book program 
    • Calendars which configures the Calendar program included in Mac OS X.
    • Reminders which sets up the “To Do” list program in Mac OS X. 
    • Notes which synchronizes documents across devices and clients.
  4. After you’ve selected the options you want, Click <Done. 
  5. Please allow a few moments for the Mail program to download your mail to the local client. If this fails, wait a few minutes or hours, and then repeat these steps.  

If at a later time, you want to disable apps such as those using Contacts or Calendars, follow these steps:

  1. Launch System Preferences -> Internet Accounts.
  2. Select the Exchange account listed on the left (do not select Exchange from the provider list on the right).
  3. Deselect the component you wish to disable and close the window.
RECOMMENDATION: For managing your Office 365 calendar, please use Outlook or Outlook Web Access (available from http://mail.duke.edu).
You can use the Calendar program included with Mac OS X but exercise caution accepting invitations from or creating invitations to fellow Duke Office 365 users.
