Adding Outlook to iPhone Download Outlook for iOS from the iOS App Store and then open it. The icon looks like this: If it's your first time using Outlook for iOS, enter your full email address, then tap Add Account. If not, open the Menu > tap Settings > Add Account > Add Email Account. Choose Office 365 as your email provider. You will now be required to sign in through the Rockhurst Portal and may have to configure a few settings. Otherwise, your Outlook account should remain logged in on your phone. Accessing your student email will be much faster.
