Plan for Change: Warning notifications for iOS apps running unsupported SDK versions

Starting late June 2026, iOS apps using Intune MAM SDK versions earlier than 20.8.0 will show a non-blocking warning to update for security and compatibility. Organizations should notify users to update apps and can use conditional launch settings to block unsupported versions.

We are continuing improvements to the Microsoft Intune mobile application management (MAM) service to ensure applications remain secure, reliable, and aligned with the latest platform capabilities. 

Starting in late June 2026, users opening iOS apps built with an Intune MAM SDK version earlier than 20.8.0 will see a warning message recommending they update to a supported app version for the best experience and continued compatibility.

[How this will affect your organization:]

Users running iOS apps with an Intune MAM SDK version lower than 20.8.0 will see a warning message. The warning will appear in iOS apps such as Microsoft Teams, Outlook, Edge and OneDrive. Note that this notification is non-blocking, users can dismiss the message and continue using the app.

[What you need to do to prepare:]

Notify users to update to the latest versions of Microsoft and third-party apps as soon as possible. The latest versions are available in Apple's App Store. For example, you can find the latest version of Microsoft Teams here and Microsoft Outlook here. 

If applicable, notify your helpdesk and support teams about the warning message. Additionally, as an IT admin you can use conditional launch settings to block unsupported app or SDK versions that are still in use:

• The Min SDK version setting to block users if the app is using Intune SDK for iOS older than 20.8.0.
• The Min app version setting to warn or block users on older Microsoft apps. Note, this setting must be in a policy targeted to only the targeted app.
