Summary
Microsoft brought its Copilot Sales Agent to general availability in Microsoft 365 Copilot, letting sellers pull CRM and Microsoft 365 work data into the flow of work, and added Anthropic's Claude Sonnet 5 as a selectable model across Copilot, including Copilot Cowork and PowerPoint.
What changed
On July 2, 2026 Microsoft announced GA of Sales Agent in Microsoft 365 Copilot for at-scale deployment across sales teams, and made Claude Sonnet 5 available in Microsoft 365 Copilot with support in Copilot Cowork and Copilot in PowerPoint, expanding model choice beyond OpenAI models.
Why it matters
Shipping a production sales agent plus multi-vendor model choice signals Microsoft is broadening Copilot from a single-model assistant into a governed, multi-model agent platform for line-of-business work. Offering Anthropic's Sonnet 5 alongside OpenAI inside its flagship enterprise product underscores that model neutrality is becoming a competitive requirement for enterprise agent suites.
