[What and Why:]<\/b><\/p>\n

Microsoft is expanding Microsoft 365 Copilot Notebooks to support TXT (.txt) and RTF (.rtf) files as reference sources. This update enables users to bring a broader range of text-based content\u2014such as transcripts, meeting exports, developer notes, and AI-generated outputs\u2014into a single AI-powered workspace. By grounding Copilot in more contextual information, this enhancement strengthens productivity and enables more comprehensive insights, summaries, and content generation.<\/p>\n

[Rollout Schedule:]<\/b><\/p>\n

<\/p>\n

    <\/p>\n
  • General Availability (Worldwide): Rollout begins early July 2026<\/b> and is expected to complete by mid-July 2026<\/b>.<\/li>\n

          		Explanation<\/b><\/td>\n

          <\/tr>\n

          <\/p>\n

          Does the change provide end users any new way of interacting with generative AI?<\/td>\n

          <\/p>\n

          		Users can now include TXT and RTF files as reference sources in Copilot Notebooks, enabling Copilot to analyze and generate responses based on additional unstructured text inputs.<\/td>\n

          <\/tr>\n

          <\/p>\n

          Does the change alter how existing customer data is processed, stored, or accessed?<\/td>\n

          <\/p>\n

          		Content from TXT and RTF files added to notebooks will be processed and accessed by Copilot alongside existing reference files to generate insights and responses.<\/td>\n

          <\/tr>\n

          <\/p>\n

          Does the change introduce or significantly modify AI\/ML or agent capabilities that interact with customer data?<\/td>\n

          <\/p>\n

          		Copilot\u2019s AI capabilities are extended to interpret and reason over TXT and RTF file content within notebooks, expanding the range of data sources used for AI-driven outputs.<\/td>\n
