Latest Message<\/th>\nTitle: Some users may experience degradation with Microsoft 365 Copilot Chat responses after uploading a file <\/p>\n

User impact: Users may experience degradation with Copilot Chat responses after uploading a file. <\/p>\n

More info: Affected users may be returned an error message stating, “Oops! Something happened. Can you try again?”<\/p>\n

Users report low-quality responses or hallucinations when Copilot Chat is prompted to respond on content within uploaded files. <\/p>\n

Current status: After analyzing service telemetry for file upload scenarios for Copilot Chat, we’ve isolated that unexpected increased request volume is causing our retry logic for Microsoft OneDrive and SharePoint Online file uploads to retry indefinitely, causing degradation in Copilot Chat responses. We’re working to isolate the source of the increased traffic to validate the root cause of impact and to determine our next remediation actions. <\/p>\n

Scope of impact: Some users may experience degradation with Copilot Chat responses after uploading a file. This section may be updated as the investigation progresses. <\/p>\n
