Which version of iOS is not supported by Microsoft Intune?

Microsoft Intune has specific requirements regarding the versions of iOS that it supports for mobile device management. The oldest versions, such as iOS 6, are not supported due to significant advancements in security features and functionality in later versions. As organizations aim to protect their data and ensure compliance, Microsoft Intune focuses on more recent iOS versions that provide enhanced security measures and better integration with enterprise applications.

Versions like iOS 7, iOS 8, and iOS 9 include updates that enhance performance, security, and user experience. These upgrades are essential for organizations looking to implement a robust mobile device management strategy. As such, using iOS 6, which lacks many of these improvements, would not meet the operational and security needs of modern enterprise environments governed by Microsoft Intune.
