OneDrive: Sync support for up to 1 million items on macOS

🚨 The Signal: OneDrive for macOS now supports syncing up to 1 million items, a significant increase from 300,000. This enhances large file set management but requires review of data governance and endpoint security for macOS devices.

The Impact

macOS users can sync more data, increasing the risk of data exfiltration or non-compliant data storage if not properly governed.

  • Security Teams: Increased data sync volume on macOS may complicate DLP monitoring and incident response.
  • Admin Teams: Requires review of existing OneDrive sync policies and macOS endpoint configurations for compliance.
  • End Users: Can sync more data, potentially increasing the risk of accidental data exposure or non-compliant storage.
  • Compliance Teams: New capacity necessitates re-evaluation of data retention and classification policies for macOS endpoints.

The Action

  1. Review and update Microsoft Purview DLP policies to account for increased data volumes on macOS endpoints.
  2. Verify Microsoft Intune compliance policies for macOS devices, ensuring adequate controls for large synced data sets.
  3. Communicate updated data handling guidelines to macOS users, emphasizing responsible data storage and sharing practices.
  4. Assess existing OneDrive sync policies in the Microsoft 365 admin center for macOS devices to ensure alignment with organizational data governance.
