If a user has an iOS device (iPhone, iPad or iPod Touch), they can set up their email account to receive emails on that device.
With iOS devices, you can use either the Mail application, that comes with the phone, or the Outlook for iOS application, available from the App Store. It is recommended to use Outlook for iOS, as this is designed with Office 365 in mind.
NOTE: Your phone will need some time to be able to download the settings for the mailbox and start downloading data. It may take a few minutes for data to appear.
If your Office 365 Administrator has disabled you from consenting to apps accessing company data, you will not be able to complete the permission request and adding the account will fail.
Outlook for iOS
Before you can use the Outlook for iOS application, you must install it from the App Store on your device. Click on the Outlook icon to be taken to the App Store Page for the application.
If it’s the first time you are using the application, you will automatically be taken to the account setup screen.
