This article describes the way to access shared Exchange calendar on mobile Android or iOS devices.

The native calendar application on mobile devices doesn't have a functionality to display any Exchange calendars except owned by a user.

It is advised to download free OWA application for Android or iOS provided by Microsoft, which allows users to view shared calendars, including delegate support. 

Note: Shared folders cannot be opened in Outlook app. You will need to use OWA app instead.

  1. Go to OWA app > click Options button
