MC911624Microsoft Purview | Data Loss Prevention: ​Network share coverage and exclusion support on Mac endpoints​

Updated February 21, 2025: We have updated the rollout timeline below. Thank you for your patience.

With this feature, sensitive data in files that are stored in network shares and mapped network drives will be protected by Data Loss Prevention (DLP) policies across Mac endpoints.

This message is associated with Microsoft 365 Roadmap ID 410397.

When this will happen:

Public Preview: We will begin rolling out early March 2025 (previously early February) and expect to complete by mid-March 2025 (previously mid-February).

General Availability (Worldwide): We will begin rolling out early April 2025 (previously early March) and expect to complete by mid-April 2025 (previously mid-March).

How this will affect your organization:

After this rollout, you can configure DLP policies to prevent your users from taking egress actions such as copy to USB, copy to clipboard, and more for sensitive files stored on network shares. This brings protection for sensitive content on files in network shares with the same protection behavior as a file on mounted hard drive. You will also an alert once any policy is matched against such actions. You can also configure exclusions for certain network shares if you desire.

What you need to do to prepare:
