Office 365, Email, Exchange, Setting up Apple Mail

This article details how to configure the Apple Mail app to use your University email account. These instructions will be accurate for most recent versions of macOS, 10.14 (Mojave) and newer.

Removing an Account for Re-Authentication

If you Apple Mail app was configured to work with your University email account sometime before 2022, it may be using the outdated and less secure Basic Authentication sign-in protocol. If this is the case, you will need to remove the account from macOS and then add it back.

  1. Click the Apple icon in the upper-left corner of the screen, and choose Force Quit...
  2. Use the Force Quit Applications window to stop the Mail app if it is running. If you do not see an entry for Mail in the Force Quit menu, continue to 3.
  3. Click the Apple icon in the upper-left corner of the screen and choose System Preferences...
  4. Click Internet Accounts to open a window listing the accounts that macOS has been configured with. Locate your University account in this list and click it to select it. If you do not see your University account here, no further action is needed.
  5. Click the - minus icon in the lower-left corner of the list of accounts to remove your University account.
    macOS may warn you about losing information, but any data stored on the University mail server will not be lost; this step only removes it from your device.

  6. If asked whether you want to sign in using Microsoft, choose Sign In (not Configure Manually).
  7. A window with a University-branded sign-in screen will appear with your email address already filled in and a prompt for your password. Input the same password that you use for other University websites and services and click Sign In.
  8. Check the boxes for the Exchange account features you'd like to use in macOS, then click Done.
