Updated April 3, 2025: We have updated the rollout timeline below. We are now one month away from this change taking effect.

We're removing the EnableAllOcsiClients OneDrive group policy in the Microsoft 365 admin center. OCSI is the coordination between office and OneDrive for syncing office documents to the cloud. 

This message is associated with Microsoft 365 Roadmap ID 429874.

How this will affect your organization:

After this rollout, the EnableAllOcsiClients group policy will be removed, and Microsoft Office and Microsoft OneDrive will be able to communicate smoothly to ensure existing Office features like autosave, version history, real time user collaboration, and merging in the case of conflicts can work properly for end users.

Before this rollout, tenants had the option to disable this feature with a GPO, and when they disable the GPO, existing Office features like autosave, version history, real time user collaboration, and merging in the case of conflicts cannot work properly.
