Introduction
With the recent transition announced in MC1275311, Microsoft is steering its suite of services to a more integrated and efficient ecosystem by consolidating agent management under the Agent 365 framework. This initiative is critical for administrators aiming to streamline the observability, governance, and security of agents across Microsoft 365 environments. This post leverages real-world experience to guide you through this transition, aligning with production needs as of May 3, 2026.
Understanding the Transition
For administrators heavily reliant on the existing Agent Registry API, the transition to Agent 365 presents both challenges and opportunities. To ensure continued operational efficiency and security, it’s crucial to adapt your scripts and applications to embrace the new API endpoints and methods offered by Agent 365.
Prerequisites and Preparation
- Ensure administrative access to the Microsoft 365 Admin Center.
- Acquaint yourself with Microsoft Graph API, which underpins the new Agent 365 framework.
- Confirm that your API permissions and OAuth tokens are up-to-date to access Microsoft 365 services.
Step-by-Step Implementation
Review API Changes
Access the transition documentation to understand deprecated API endpoints. It is crucial to know the differences in method signatures and scopes, as this knowledge informs the adjustments needed in your integration process.
API Endpoint Migration
The first step in implementing this transition is identifying all instances where the Agent Registry API is utilized. You will need to replace these with their corresponding Agent 365 endpoints. Consider a small example:
// Old endpoint
GET https://graph.microsoft.com/v1.0/agentRegistry/{id}
// New endpoint
GET https://graph.microsoft.com/v1.0/agent365/{id}
It’s imperative to meticulously review your scripts, ensuring each call is updated, with special attention to any changes in required parameters or permissions.
Integrating with Microsoft Graph API
Microsoft Graph offers a robust suite of APIs that facilitate agent management under Agent 365. Below is an example code snippet to demonstrate authenticating and making API calls using PowerShell:
<#
.SYNOPSIS
Connects to Microsoft Graph with the required scopes and updates agent configurations.

Connect-MgGraph -Scopes "https://graph.microsoft.com/.default"
$agentId = "YOUR_AGENT_ID"
$response = Invoke-RestMethod -Uri "https://graph.microsoft.com/v1.0/agent365/$agentId" -Headers @{Authorization = "Bearer $($token)"} -Method GET
Write-Host $response
This script connects to the Microsoft Graph and retrieves data for a specific agent under the new Agent 365 endpoint. Replace "YOUR_AGENT_ID" with the appropriate value from your environment.
Testing New Integrations
After making necessary code changes, conduct thorough integration tests. This will confirm the functioning of your applications under the new Agent 365 architecture. Pay particular attention to authorization flows and data retrieval methods to preempt any disruptions.
Monitoring for Errors
Implement robust logging mechanisms to capture any anomalies or unexpected behaviors in API calls. This will provide insights into any areas that need refinement post-transition.
Managing Transition Risks
Legacy Authentication Tokens
Legacy tokens may not encompass permissions for the new Agent 365 endpoints. Ensure all tokens issued during transition reflect updated scopes, mitigating potential access issues.
Deprecation of Old Methods
It’s possible that some methods previously available in the Agent Registry API are deprecated. Always cross-reference with the latest Microsoft migration guides and update documents accordingly.
Conclusion
Transitioning to the Agent 365 framework is a significant step towards more efficient and secure management of agents within Microsoft 365. By following the steps outlined here, administrators can ensure a smooth transition that minimizes disruption and maximizes operational benefits.
