The Azure File Sync v21.2, is being flighted to servers which are configured to automatically update when a new version becomes available and is available on the Microsoft Update Catalog.
This article recap the new features introduced.
Improvements
- Azure File Sync in Italy North GA: the expansion into Italy North brings the service closer to organizations in these regions, offering lower latency, better performance, and support for local data residency requirements.
- Granular Role-Based Access Control (RBAC) for Azure File Sync: Azure File Sync now includes two dedicated built-in RBAC roles Azure File Sync Administrator and Azure File Sync Reader, designed to strengthen security and streamline operations for organizations managing file synchronization between on-premises and cloud environments. These roles offer more granular access control than broader roles like Owner or Contributor, enabling organizations to enforce the principle of least privilege more effectively.
- Miscellaneous reliability and telemetry improvements for cloud tiering and sync: fixed an issue that caused sync download and cloud tiering failures with error code 0x80c80362 (ECS_E_ITEM_PATH_COMPONENT_HAS_ TRAILING_DOT) when a file or folder path included a trailing dot. Previously, users had to manually rename the affected item to resume sync. Azure File Sync now correctly handles path components with trailing dots, eliminating the need for manual intervention.
Notes
- This release is available for Windows Server 2016, Windows Server 2019, Windows Server 2022 and Windows Server 2025 installations
