Who needs to do this

This applies to you 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) at the end of 2022 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 University Exchange Online account

1. Open System Preferences and select Internet Accounts

2. Select your University Exchange Account (the default name is Exchange, but you may have given it a different name):

3. Click the [–] button at the bottom of the account list :

4. Click OK to confirm:

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 University Exchange Online account

1. Open System Preferences and select Internet Accounts:

2. Select Microsoft Exchange:

3. Fill in your full name and email address, and click Sign in:

4. You will be prompted to sign into your account using Microsoft. Click Sign in:

5. Enter your Raven password and click Sign In:

6. Choose how to verify your identity (two factor authentication):

7. Choose the Mac apps that you’d like to use and click Done. 


If you are using macOS Monterey you will now be prompted choose a Mail Privacy Protection option.

Your email will now be downloaded from the cloud to your Mac. It may take a few minutes until you see your email in the Mail and Calendar apps.
