Microsoft is preparing to retire OWA mobile apps in May 2018, and they encourage all users to begin using Outlook for iOS and Android.
In mid-April, OWA mobile apps will no longer be available for download in app stores and on May 15, 2018, existing OWA mobile apps will be retired.
Starting in April, users will be informed about the app’s retirement through an in-app message, but you may want to communicate the change to your users. Click here for step-by-step user setup instructions for Outlook for iOS and Android.
Microsoft encourages you and users across your organization to take advantage of Outlook for iOS and Android going forward as the best way to experience Office 365 features on a mobile device.
This change does not affect anyone already using Outlook for iOS and Android.
