Microsoft Agent 365 SDK Overview

Important

You need to be part of the Frontier preview program to get early access to Microsoft Agent 365. Frontier connects you directly with Microsoft’s latest AI innovations. Frontier previews are subject to the existing preview terms of your customer agreements. As these features are still in development, their availability and capabilities may change over time.

Agent 365 SDK is a software development kit that can be used to extend agents built using any agent SDK or platform, with enterprise‑grade identity, observability, notifications, security, and governed access to Microsoft 365 data. Agents can have unique identities, can be invoked using common gestures (such as @mentions) in apps that enterprise users typically operate in (such as Teams, Word, Outlook, etc.), demonstrate observable behaviors building trust, taking auditable actions, and achieving it all via secure access to tools and data.

With the Agent 365 SDK, agents can:

  • Use Entra-backed Agent Identity with their own user resources like mailbox for secure authentication and controlled access to tools and data.
  • Receive and respond to notifications from Teams, Outlook, Word comments, and emails—just like a human participant in Microsoft 365 apps.
  • Gain full observability via Open Telemetry, enabling audited, traceable agent interactions, inference events and tool usage.
  • Invoke governed Model Context Protocol (MCP) servers to access Microsoft 365 workloads (eg. Mail, Calendar, SharePoint, Teams) under admin control..
  • Function within an IT‑approved blueprint system, ensuring each agent instance inherits compliance, governance, and security policies.
