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: We’re implementing a configuration change to prevent indefinite retries from occurring during OneDrive or SharePoint Online file uploads along with implementing performance optimizations on affected service infrastructure to assist with processing the requests. <\/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

Start time: Tuesday, June 09, 2026, at 6:00 AM UTC <\/p>\n

Next update by: Thursday, June 11, 2026, at 1:00 AM UTC<\/td>\n<\/tr>\n
