Intune MAM is a way to secure the corporate data on a App level. The MAM policy block for different user action, ensure encryption and authentication to the app.
This is a light way of doing the Intune MAM policy – the full MAM functions is still available in the Intune App protection part of Intune.
So the SharePoint administrator can create a Intune MAM policy that applies to all users in the tenant – with out any knowledge to Intune.
This policy only applies to users in your organization who are licensed for Microsoft Intune directly or indirectly trough the Enterprise Mobility + Security E3 or E5 license.
How to create the MAM policy as a SharePoint Admin
Start the OneDrive admin portal https://admin.onedrive.com/
Go to Device access
Click on Deploy this policy
Change the settings to match your security requirements
In a few minutes the policy will show up in Intune App protection console as deployed global to IOS and android platform.
The 2 apps is OneDrive for IOS and Android – take a look in the target apps inside the policy
In the OneDrive mobile policy – Policy settings
