Final Update: 04/03/2025 08:45:00 AM – Microsoft have completed deploying the permanent fix to the affected infrastructure, and after a period of monitoring, they’ve determined impact is now resolved.

Scope of impact: Any organization may be affected by this event, and some users” OneDrive for Business content may be in read-only mode.

Root cause: A recent policy enforcement rollout interacted negatively with a configuration leveraged by your organization. Specifically, this problem occured when OneDrive for Business ownership was applied to a group or service account, which is an unsupported scenario. Microsoft’s efforts to address this impact introduced a secondary issue in which recently licensed users were registered as unlicensed users in their systems, which also resulted in read-only states for users.

Next steps: Microsoft are reviewing their change management process to better understand how the impacting change was not detected in their testing cycle.
