MC1058262 - Microsoft Purview | Insider Risk Management: Enhancements to global exclusions in IRM settings

Coming soon for Microsoft Purview | Insider Risk Management (IRM): Enhancements to IRM exclusions to reduce alert noise.

This message is associated with Microsoft 365 Roadmap ID 486826 and Roadmap ID 483485.

When this will happen:

Public Preview: We began rolling out mid-April 2025 and expect to complete by late April 2025.

General Availability (Worldwide, GCC, GCC High, DoD): We will begin rolling out late April 2025 and expect to complete by early May 2025.

How this will affect your organization:

Customer can use this feature to tune down the noise

• Keyword logic update for email: An email will be excluded from scoring only when all the attachments match the keyword exclusions or email subject matches the keyword exclusions. This will be helpful to reduce the email signature noise that commonly contains keyword "image."
• Keyword exclusions on both target and source file paths: For signals like File copied to removable media, keyword exclusions apply on both target and source file paths.
• File path exclusions for removable media: We will start supporting file path exclusions for removable media.
• Exclusion support for browser: Domain exclusions will be supported for browsing indicators.

These enhancements will be available by default for admins to configure.

What you need to do to prepare:

To get the most out of this feature, admins need to update the exclusion settings at IRM Settings > Global exclusions.

This rollout will happen automatically by the specified dates with no admin action required before the rollout. Review your current configuration to assess the impact on your organization.
