Overview
Box and Microsoft have enabled a new capability for Intune Mobile Application Management (MAM aka App Protection Policy) that allows saving copies of org-managed documents to Box from the relevant Microsoft mobile apps (i.e. Office, Word, PowerPoint, Excel, and Outlook apps). Previously, enterprises that leveraged Intune MAM were limited to OneDrive and SharePoint as managed cloud storage providers. Box as a Managed Place in Intune now provides enterprises the option to control the flow of managed data to move between Microsoft and Box, and block any attempts to save copies of org-managed data outside of Box.
Supported Microsoft Mobile Apps
iOS: Office, Word, Powerpoint, Excel, Outlook
Android: Office, Word, Powerpoint, Excel
Technical Requirements
Enterprises will be required to have Azure Active Directory (AAD) or Okta federation for their Box login in order to utilize the Box as a Managed Place functionality in the relevant Microsoft mobile apps. Enterprises are not required to have a Mobile Device Management (MDM) solution to enable the functionality because the functionality is part of Microsoft's Intune MAM policy aka app protection policy, meaning it's available for both MDM enrolled devices and unenrolled devices.
Enable Box as a Managed Place from the Microsoft Intune Portal
To enable the Box as a Manage Place functionality, a Microsoft Intune admin at your enterprise must log into the Microsoft Endpoint Manager admin center and navigate to the relevant MAM policy aka app protection policy that is associated to their enterprise's relevant Microsoft mobile apps.
From the MAM policy, click on the Edit button within the "Data protection" section of the policy and find the "Save copies of org data" policy setting. Select "Block" and then under the "Allow user to save copies to selected services" dropdown, select "Box". This will block saving copies of org data outside of Box within the relevant Microsoft mobile apps associated to the MAM policy, i.e. saving copies of org data is allowed only within Box.
End Users Enabling Box as a Managed Place
End users will first need to install the latest version of the relevant Microsoft mobile apps. Once installed, a user should navigate to the Open tab (folder icon) and in the "Other Storage" section, select "Add Storage Account" and then select Box. Once the end user has successfully authorized Microsoft to access their Box account, they're all set, and the relevant Intune MAM policies will be applied to the end user.
