I’m thrilled to share that Microsoft has been recognized as a Leader in the 2026 Gartner® Magic Quadrant™ for Document Management! We are honored to be positioned highest for Ability to Execute. Over the past year we’ve invested heavily in making SharePoint and OneDrive the governed knowledge foundation for the AI era — grounding Microsoft 365 Copilot on trusted content, bringing custom agents into every document library, and strengthening governance across the content lifecycle. Thank you to our customers and partners for making this possible! aka.ms/2026GartnerDocMgmtMQ
