Microsoft Adds Command-Line Interface for OneDrive Sync Management
IT admins can now use a new CLI tool to audit OneDrive sync status and policy compliance across enterprise devices without manual checks.
Key points
- Microsoft launched the OneDrive Sync Client CLI at its OneDrive + Copilot event.
- The tool outputs JSON data for integration with scripts and Microsoft Intune remediation jobs.
- Admins can verify Group Policy settings and Folder Backup configurations via PowerShell.
Microsoft introduced a new command-line interface for managing OneDrive sync deployments during its OneDrive + Copilot event. The tool allows IT administrators to quickly check and manage sync settings across company devices without navigating graphical interfaces.
The OneDrive Sync Client Command Line Interface runs via a simple odsync command in PowerShell. According to the demonstration, it provides detailed device health information, including client versions, account lists, and installation methods. This replaces the need for digging through log files or settings screens.
Operational Capabilities and Data Format
The CLI lists every OneDrive account configured on a device, even those with multiple accounts. It allows users to narrow results to a specific account and displays whether OneDrive is actively running. Admins can also view Folder Backup settings to see which local folders are syncing to the cloud.
A critical feature for security teams is the ability to view Group Policy settings applied to the sync client. This helps confirm that devices adhere to company rules. The tool reports overall status at the client, account, and Folder Backup levels, with verbose output available for deeper troubleshooting when issues arise.
Microsoft states the tool works in both interactive and non-interactive modes. It returns results in JSON format, making it easy to plug output into scripts, Microsoft Intune remediation jobs, or reporting tools. The design targets admins, developers, scripts, and AI agents like GitHub Copilot CLI.
Security Implications and Affected Environments
OneDrive sync is often a blind spot in enterprise environments. Settings that drift from policy can leave sensitive files outside approved storage or sync them to unauthorized locations. Until now, checking for these issues required custom scripts, registry checks, or third-party utilities.
Cyber Security News previously reported how OneDrive auto-sync exposed enterprise secrets in SharePoint Online. Small sync mistakes can grow into real data leaks. Threat actors have also abused the sync client itself, exploiting OneDrive.exe through DLL sideloading to run malicious code.
What should you do?
IT teams managing large Microsoft 365 setups should evaluate this new tool for compliance auditing. The ability to script checks for Folder Backup status and Group Policy adherence can help identify devices that have drifted from security baselines.
What to do and how to stay safe: Microsoft
- Audit current OneDrive deployment scripts to identify opportunities for replacing manual checks with the new CLI tool.
- Verify that Group Policy settings for OneDrive are correctly applied by using the CLI to query device configurations.
- Monitor Folder Backup settings across endpoints to ensure sensitive local data is not syncing to unauthorized cloud locations.
- Review access controls for the OneDrive sync client to mitigate risks associated with DLL sideloading exploits.
