Overview
The job aid is for Colleagues that want to access Outlook (part of Office O365) work email on their iOS phones,
and eventually other O365 apps as they are rolled out.
High Level: Steps Required to Access Outlook on your iPhone
In this document we will show you how to:
1. Set up Azure Multi-Factor Authentication (MFA) (job aid links below)
2. Download and set up Outlook O365
3. Download supporting Office applications, such as Excel and Word, as needed
Set up Multi-Factor Authentication (MFA)
The first pre-requisite for using Outlook on your phone is to enroll in and set up your Multi-Factor Authentication
(MFA) account at the MFA set up website. Set up steps are detailed in the linked job aids below. As part of this
process you also need to get and install the Microsoft Authenticator app from the App store.
Azure Multi-Factor Authentication (MFA) is required for second factor authentication on mobile devices. MFA
helps safeguard access to data and applications while meeting user demand for a simple sign-in process. MFA is
Microsoft's two-step verification solution for users who are logging in to Office 365 applications (for example,
Outlook O365) when not on the Trinity Health network. You can choose from two authentication methods – pop-up
notification or phone call prompt -- as described in the job aids linked below.
Enroll in MFA:
Recommended, more secure method: Receive a pop-up notification on your smart phone to approve
authentication (Enrolling in Azure MFA to Access O365 with a Mobile App)
Receive a phone call on your smart phone to approve authentication (Enrolling in Azure MFA to Access O365
with a Phone Call)
Note: MFA replaces Citrix SecureHub and other applications you may have used with Outlook on your mobile device. See the
last page of this document for information about uninstalling all Citrix SecureHub applications from your phone.
Download and Set Up Outlook O365
Important: It is essential that you do not set up and sign into Outlook O365 until you are certain your mailbox has
been migrated to the O365 Cloud. Using Outlook prematurely may jeopardize your mailbox migration.
