Microsoft now enforces stricter security within Intune

"The change revolves around Intune Mobile Application Management. From now on, Microsoft will only allow apps that are built with recent SDK versions or are correctly packaged with the latest Intune wrapper. Apps that do not comply with this will be automatically blocked. This affects not only internal or custom applications, but also commonly used Microsoft apps such as Outlook, Teams, and OneDrive on both Android and iOS, if they have not been updated via the App Store or Play Store."

"For Android, the Intune Company Portal plays a key role. If this app has not been updated to a recent version, other managed work apps on the same device may also refuse to start. A single overdue update can therefore paralyze the entire mobile work environment. On iOS, the emphasis is less on the portal and more on the SDK or wrapper used, which mainly affects organizations with their own line of business apps."

"Microsoft itself reports that organizations have been notified of this change via the Microsoft 365 Message Center since September 2025. December 15, 2025 was mentioned as the intended effective date, with the addition that enforcement would follow shortly thereafter. This explains why users are only now actually being blocked. According to Microsoft, this generous transition period was necessary to give administrators and development teams sufficient time to adapt their apps and policies."

Microsoft has begun enforcing stricter security requirements in Intune that block apps built with older SDK versions or not packaged with the latest Intune wrapper. Noncompliant apps are automatically blocked, affecting internal, custom, and widely used Microsoft apps such as Outlook, Teams, and OneDrive on Android and iOS if they are not updated through the App Store or Play Store. On Android, an outdated Intune Company Portal can prevent other managed work apps from starting and can paralyze the mobile work environment. On iOS, enforcement focuses on the SDK or wrapper used, primarily impacting organizations with line-of-business apps. Organizations received advance notice and a transition period before enforcement.
