MC364310: Update Microsoft Defender for Endpoint and MDM policy to newest version

We want to let you know that running very old versions of Microsoft Defender for Endpoint (MDE) can result in an invalid agent state and loss of protection. Mobile device management (MDM) previously configured to deploy very old MDE version may expose your organization to the risk of the invalid agent state and protection loss.

If you do not have macOS and Linux devices in your environments, you can disregard this message.

MC364310: Update Microsoft Defender for Endpoint and MDM policy to newest version

What you need to do to prepare

Review the following recommendations to assess potential impact on your current configuration or end user education.

  • Check your Mac devices to ensure that (MAU) is enabled, and devices are getting updated
  • When onboarding a new device, download the MDE package from the Microsoft 365 portal and avoid using previously downloaded packages
  • Check your MDM policies regularly to ensure you are pushing the updated version MDE from the Microsoft 365 portal.
  • Due to series of recent breaking changes, ensure you never push a version older than: Linux 101.62.74
    Mac 101.61.69
  • Ensure that your MDM is configured to ignore the app version if MDE is already installed on the devices.
  • On your macOS devices, configure Microsoft Auto Update (MAU) to deliver updates automatically
