iPhone Outlook Multi-Factor Authentication Setup

Once you are enrolled with Multi-Factor Authentication, you will need to authenticate your iPhone Mail Client. If you do not want to use the native mail app, you can use the Outlook Client for iOS.

Navigate to the App Store and search for Microsoft Outlook. Install the app and select OPEN.
Outlook may detect other accounts on your device. If your work email is detected, you will want to remove it first in order to prevent any issues. Select the Skip option if this appears.
Enter your email address in the field provided and select Add Account.
Enter your password when prompted and select Sign In.
Verify your account using the method you previously setup.
Follow the on screen prompts for your verification method.
On the Add Another Account screen select Maybe Later.
On the Enable Notifications pop up choose your preference.
If you chose to allow notifications you will receive a second prompt for verification.
Your Inbox will now be displayed. It may take a few minutes for your emails to load.
