Frequently Asked Questions

What are the common file types currently supported by Copilot?

Microsoft Copilot typically supports standard Office formats such as Word documents (.docx), Excel spreadsheets (.xlsx), PowerPoint presentations (.pptx), and standard PDF files. Support for other formats is continuously being added.

Why are MSG files not fully supported by all Copilot Agents yet?

MSG files are proprietary Outlook email formats containing complex metadata, embedded images, and attachments. Integrating them into AI agents requires specific parsing capabilities that Microsoft is systematically developing and rolling out.

How can I convert MSG files to a supported format?

You can open MSG files in Microsoft Outlook and 'Save As' or 'Print to PDF' to convert them into a standard PDF format, which is widely supported by Copilot Agents for data extraction and summarization.
