Microsoft 365 Copilot Introduces Agent-to-Agent Communication
Microsoft 365 Copilot now supports agent-to-agent communication. The update enables declarative AI agents to collaborate directly within enterprise environments.
What happened?
Microsoft has implemented Agent-to-Agent support in Microsoft 365 Copilot for declarative agents using Microsoft 365 Copilot agents. General availability commenced in late August 2026, with updated timelines issued in October 2026. The update provides IT administrators with new governance tools in the Microsoft 365 Admin Center to manage and approve connections between various AI agents.

Why it matters

Simultaneously, it places greater demands on organisational IT governance, as administrators must actively oversee permissions and approve agent connections.
Who is affected?
The update affects IT administrators, software developers, and security officers managing Microsoft 365 environments. End users gain access to automated workflows where specialised agents can collaborate directly with one another.
Impact on the EU
The feature is being rolled out globally via the Microsoft 365 Admin Center and includes European tenants without any regional restrictions mentioned in the announcement. No specific regulatory exemptions have been communicated for the EU.
What else you should know
The update was clarified in October 2026 with a revised schedule following the start of general availability in late August 2026. Administrators are advised to review security settings before approving new connections.
