Microsoft Identifies Graph API Change as Cause of Universal Print Sharing Disruption
AI-generated from multiple sources. Verify before acting on this reporting.
Microsoft has identified a recent code modification to its Graph API as the root cause of ongoing disruptions affecting Universal Print sharing capabilities globally. The issue, confirmed by the company on Tuesday, prevents users from creating printer shares within the Universal Print service.
The technical failure stems from a code change introduced to the Microsoft Graph API, which inadvertently increased directory replication latency within Entra ID. This latency exposed a pre-existing race condition in the share creation flow for Universal Print. The combination of these factors has resulted in widespread service degradation for enterprise customers relying on the cloud-based printing solution.
Universal Print is a cloud service that allows organizations to manage printers across different locations without requiring on-premises infrastructure. The disruption affects the core functionality of sharing printers, a critical feature for businesses that depend on the service for document distribution and workflow management. Microsoft stated that the issue is currently impacting users worldwide.
The company acknowledged the problem after monitoring systems detected anomalies in the Graph API performance metrics. Engineers traced the degradation to the specific code update, which altered how directory data is synchronized. The increased latency caused timing conflicts in the Universal Print service, triggering the race condition that blocks share creation requests.
Microsoft has not yet provided a specific timeline for a full resolution, though the company is working to address the underlying code change. The focus remains on stabilizing the Graph API and mitigating the replication delays that are exacerbating the issue. Until the latency is reduced, the race condition will likely continue to interfere with printer share operations.
Enterprise IT administrators have reported difficulties in deploying new printers and managing existing print queues. The disruption has forced some organizations to revert to legacy printing methods or delay planned migrations to Universal Print. Microsoft has advised customers to monitor service health dashboards for updates regarding the incident.
The incident highlights the interconnected nature of Microsoft's cloud infrastructure, where a change in one service can ripple through dependent systems. While the company has isolated the cause, the complexity of the fix remains uncertain. Questions persist regarding how long the service degradation will continue and whether additional patches will be required to fully resolve the race condition.
Microsoft continues to investigate the scope of the impact and is preparing to communicate further details to affected customers as the situation develops.
