Controls to manage file uploads in Microsoft Copilot and Microsoft Copilot Chat

File upload is enabled by default in both Microsoft Copilot and Microsoft Copilot Chat. It lets users upload files like Word docs, Excel files, and PDFs to prompt Copilot and Copilot Chat to reason over them as part of its response. File upload limits apply in Copilot Chat.

If you don't want users to have the ability to upload files in Microsoft Copilot and Microsoft Copilot Chat, contact Microsoft Support so they can configure the file upload control for you. Depending on your organization's needs and policies, ask about the following options:

• Allow file uploads in both Microsoft Copilot and Microsoft Copilot Chat: Allows users to upload files in both experiences. This is the default setting.
• Prevent file uploads in both Microsoft Copilot and Microsoft Copilot Chat: Disables file upload in both experiences.
• Disable file uploads in Microsoft Copilot Web mode and Microsoft Copilot Chat while allowing file uploads in Microsoft Copilot Work mode: Enables file upload in Microsoft Copilot Chat Work mode only and disables file upload in Microsoft Copilot Web mode and Microsoft Copilot Chat.

Changes to the file upload control could take up to 24 hours to be reflected for end users.

If users are prevented from uploading files in Microsoft Copilot and Microsoft Copilot Chat, the Files tab doesn't appear for those users in the Microsoft Copilot app.
