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 or inaccurate responses when Copilot Chat is prompted to respond on content within uploaded files.<\/p>\n

Current status: We\u2019re adding resources in regions that were experiencing high demand and gradually allowing more file upload traffic to resume. We\u2019re also implementing a configuration change to prevent retries from adding more load during OneDrive or SharePoint Online file uploads. We\u2019ll monitor the affected environment during peak usage periods to confirm whether the added resources are sufficient to fully mitigate impact.<\/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

Root cause: We\u2019ve determined that normal growth in Microsoft 365 Copilot usage exceeded the available resources needed to process OneDrive and SharePoint Online file upload requests, causing some requests to process slower or fail.<\/p>\n

Next update by: Thursday, June 11, 2026, at 5:00 PM UTC<\/td>\n<\/tr>\n
