Configure Exchange Online with Outlook for macOS or Mac Mail

On this page:


Overview

Note:
In order to use Apple Mail in IU's Exchange Online environment, you need macOS 10.14 or higher, which is required to support modern authentication. Modern authentication has ended support for Apple Mail on macOS High Sierra 10.13 and older versions.
Important:
IU's Exchange Online environment does not support IMAP. For email configuration instructions, including details for those using Linux and Thunderbird, see Configure your email client for Exchange Online.

In macOS, many online accounts, including Exchange, can be set up in System Preferences, available to installed applications.

Instructions

Follow the appropriate instructions below to set up your Exchange Online account with macOS.

Set up Exchange Online in System Preferences for Mac Mail

To set up Exchange Online in System Preferences for Mac Mail:

  1. Click the Apple menu, and select System Preferences.
  2. Double-click Internet Accounts.
  3. From the options on the right side of the "Internet Accounts" dialog box, choose Exchange.
  4. In the setup dialog box that appears, enter your name and IU email address as username@iu.edu (not a campus email address), and then click Sign In.
  5. If you are prompted with options for Configure Manually or Sign In, choose Sign In.
  6. In the IU Login dialog box that appears, sign in with your IU passphrase. You may also be prompted to authenticate with Duo.
    Note:
    If you are not prompted to authenticate with Duo, and you see an error that says "We're sorry, access is not allowed because you are not enrolled. Please contact your organization's IT help desk for assistance", you'll need to enroll a device in Duo before you can proceed. For more, see Get started with Two-Step Login (Duo) at IU.
    Note:

    If you are prompted to enter an internal URL and an external URL, use the following URL for both:

    https://outlook.office365.com/EWS/Exchange.asmx
    
  7. In the next dialog box, select the Exchange items you want the store to be able to access, and then click Done. You will be returned to the "Internet Accounts" dialog box with your Exchange account listed on the left. Your Exchange Online email is now configured for Mac Mail and Calendar.
Note:
If you experience an error when adding your email address, try entering it as username@exchange.iu.edu in the address field and username@iu.edu in the username field.

Set up Exchange Online in Outlook for macOS

To set up Exchange Online in Outlook for macOS:

  1. Open Outlook by either searching for Outlook with the Spotlight menu, or, if an icon is in your dock, click the icon in the dock.
  2. If you are setting up Outlook for the first time and/or have deleted old profiles using the directions in the note above, you should be prompted with the option to add your Exchange account (likely listed as just your IU username or as username@iu.edu). Click Add [your username or email address].

    If you are not prompted with the option to add your Exchange account:

    1. Click the Outlook menu, and select Preferences....
    2. In the "Outlook Preferences" window, click Accounts.
    3. In the bottom left, click the + (plus sign) and select New Account....
    4. Enter your IU email address as username@iu.edu (not a campus email address), and then click Continue.
  3. Log in using your passphrase and Duo if prompted (if you have logged in previously, it may simply continue). Outlook should then display "Connecting to Office 365", followed by a message saying "[your account] has been added".
    Note:
    If you are not prompted to authenticate with Duo, and you see an error that says "We're sorry, access is not allowed because you are not enrolled. Please contact your organization's IT help desk for assistance", you'll need to enroll a device in Duo before you can proceed. For more, see Get started with Two-Step Login (Duo) at IU.
  4. Click Done, or to add additional accounts, click Add Another Account and follow the prompts.
  5. You may need to authenticate once more with Duo. After a few seconds, your Exchange account will populate in Outlook.
  6. Click Show All to reveal the other Outlook settings, and then click Calendar. Next to "Default time zone for new events:", make sure it is set to the correct time zone. Especially if you have an Indiana city set for your Mac's system-wide time zone setting, make sure it is not set to Indiana (East), but instead to Eastern Time (US & Canada).
