NHSmail Reference : INC32310999
Microsoft Reference : IT448934
Issue Status : RESOLVED
Issue Description : Mobile Application Management (MAM) Application configuration policies may not be delivered.
More info : MAM Application Configuration policies may not be delivered to some users.
Specifically, when admins specify an intended management level (‘managed’ / ‘unmanaged’) for a MAM application protection policy, and an application configuration policy is also targeted to the same user and app, MAM fails to deliver the application configuration specified.
Scope of impact : Intune MAM users with App Protection Policy set to Management Level ‘managed’ or ‘unmanaged’ are affected by this issue.
Final Update : 26/10/2022 08:40:00 AM – Microsoft has confirmed via telemetry that the fix has finished saturating throughout the affected environment and the impact is resolved.
Root Cause : A code regression in recent service update is resulting in impact.
Next steps : To help prevent similar impact in the future, Microsoft is further reviewing why the service update contained a code regression and how we can improve our validation procedures to catch such issues before deployment.
