Who needs to do this

You need to do this if you use the Apple Mail and Calendar apps to connect to your University Exchange Online account.

Why it must be done

Microsoft will stop supporting 'basic authentication' (ADFS) later this year in favour of using a more secure method instead. When this happens, your Apple Mail and Calendar apps will stop connecting to your University Exchange Online email account because the settings need updating.

Unfortunately, you can't just edit your existing account settings. You must delete your University Exchange Online account and set it up again. You will not lose email or calendar data as a result of doing this, but the data on your device will be removed and then downloaded again.

Part 1: Remove your old Exchange Online account

  1. Open the Settings app
  2. Tap Mail
  3. Tap Accounts
  4. Tap your University Exchange Online account (you may have given it a custom name, for example, 'work' or 'Exchange'.)

  5. Tap Delete Account

  6. Tap Delete from my iPhone (or similar text, depending on your device)


This will delete the Exchange Online mailbox and calendar data from your device. It will be put back when you add your Exchange Online account again.

Part 2: Add back your Exchange Online account

  1. Open the Settings app
  2. Tap Mail
  3. Tap Accounts
  4. Tap Add account

  5. Tap Microsoft Exchange

  6. Email address = your email address
  7. Description = a description of your choice (for example. 'work').
    If you leave the Description blank, the default will be 'Exchange'.
  8. Tap Next

  9. Tap Sign In
    Your Exchange account details will be verified.


  10. Choose the apps you want to sync your Exchange data with and tap Save

  11. You will now see your new Exchange account listed and your mailbox and calendar data will be downloaded to your device again.
