Microsoft has launched an investigation into a widespread issue affecting Microsoft Copilot in Microsoft 365, where users are experiencing significant limitations when performing actions on files.
The technology giant confirmed the incident via official Microsoft 365 Status channels, assigning the tracking identifier CP1188020 for administrative reference.
The Issue and Impact
The reported problem prevents users from executing any operations on files directly within the Microsoft Copilot interface.
This includes activities such as uploading, downloading, editing, sharing, or otherwise manipulating documents and files that users need to work with through the Copilot application.
The disruption has affected multiple users across the Microsoft 365 ecosystem, suggesting a potentially significant infrastructure or application-level issue.
The inability to process files through Copilot directly impacts productivity workflows that rely on the AI assistant to analyze documents, extract information, or perform collaborative file management tasks.
Organizations leveraging Copilot for document intelligence and file processing have reported workflow interruptions, forcing teams to seek alternative methods for file handling.
Microsoft’s incident management team has officially acknowledged the situation through the Microsoft 365 Status communication channel, confirming that technical teams are actively investigating the root cause.
Additional technical details and real-time updates on the investigation progress are available in the Microsoft 365 admin center under the incident ticket CP1188020.

The incident highlights the importance of having backup workflows and contingency plans for critical file management operations that depend on cloud-based AI services.
Organizations should ensure their teams are aware of alternative methods for completing essential file-related tasks.
