CIS Microsoft Intune for Office Benchmark

Description

CIS Microsoft Intune for Office Benchmark, recommendation 2.5.14.3.24 (Level 1).

The test passes when an assigned settings catalog policy for Windows sets Microsoft Outlook 2016 > Security > Security Form Settings > Outlook Security Mode to Enabled, with Prevent users from customizing attachment security settings set to Enabled in the same policy, and no other assigned policy sets it to something else.

Remediation action

1. In the Microsoft Intune admin center, go to Devices > Configuration and open (or create) a settings catalog policy for Windows 10 and later.
2. Add Microsoft Outlook 2016 > Security > Security Form Settings > Outlook Security Mode and set it to Enabled, then set Prevent users from customizing attachment security settings to Enabled.
3. Assign the policy to your Windows devices, and remove any other assigned policy that sets it to something else.
