Most folks I talk to think agents are just Copilot with extra steps. They’re not.
A Copilot prompt is a single user, asking a single question, in a single session. An agent keeps running. It has tools, it has access, it makes decisions, and it does all of that whether you’re watching or not.
Agents don’t sleep. They also don’t ask permission.
That’s the part nobody seems ready for. Last year your tenant had users. This year it has users and agents. Some you bought, some your developers built, some your staff spun up in Copilot Studio over the weekend and forgot about.
So here’s the question I keep asking MSPs: do you actually know how many agents are running in your client’s tenant right now? If the answer is “probably some”, that’s not governance. That’s hope.
Microsoft Agent 365 is the control plane for agents. That’s it. It’s not a new agent. It’s not a new Copilot. It’s the place you go to see every agent in the tenant, decide what each one is allowed to do, and shut down the ones that shouldn’t be there.
Think of it like the Microsoft 365 admin centre, but for non-human accounts. The agents your team built. The agents your vendors sold you. The agent embedded inside that SaaS app marketing signed up for last quarter. All of them, in one registry, with one set of policies.
It went generally available on 1 May 2026 at USD$15 per user per month, and it pulls Microsoft Entra Agent ID(opens in new window), Microsoft Purview, and Microsoft Defender into a single agent lifecycle story. The official overview lives on Microsoft Learn(opens in new window).
Notice what’s missing? You. The user. Agent 365 isn’t an end-user tool. It’s for admins, MSPs, and security folks. It’s the dashboard your clients don’t see — and the one that keeps them out of trouble.
Step-by-Step: Finding the agents already in your tenant
The first thing I’d do in any tenant is just look. You’ll be surprised.
Sign in to the Microsoft 365 admin centre
Go to admin.microsoft.com as a Global Admin or AI Administrator.
Open the Agents workload
In the left navigation, expand Agents and select Overview. That’s the Agent 365 dashboard. If the tenant has a qualifying licence, you’ll see Agent 365 branding. If it doesn’t, you still get the baseline agent management view.
Review the registry
Select All agents. This lists every agent the tenant knows about — Copilot Studio agents, declarative agents, SharePoint agents, third-party agents, and anything registered via the new Agent 365 API. Each one shows its owner, source, and current status. The admin centre docs(opens in new window) walk through the columns.
Hunt for ownerless agents
Filter by owner. Anything marked ownerless is a red flag — that’s an agent doing things in the tenant with no human accountable for it. Assign an owner or block it. Don’t leave it.
Apply a policy
From an agent card, set access policies — who can run it, what data it can touch, whether it needs review before it publishes. Use the policy templates rather than rolling your own.
Before Agent 365, the question was “what agents are we using?” After Agent 365, the question is “what agents are we allowing?” Different question, different answer.
Why this actually changes the game
Here’s the real win. Agents inherit risk in a way users don’t. A user clicks a phishing link and one mailbox is compromised. An agent with delegated access and a bad prompt can touch SharePoint, send mail, and rewrite records — at machine speed, across hundreds of users — before anyone notices.
That’s why Agent 365 leans on Entra Agent ID to give every agent a first-class identity. No more agents hiding behind a generic service account. Each one shows up in sign-in logs, audit logs, Conditional Access, and Defender. You can revoke an agent the same way you’d revoke a user.
That’s not a feature. That’s a fundamental shift in how you secure a tenant.
My recommendation?
If you’re an MSP, start the conversation with your clients this quarter. Open the admin centre. Show them the agent list. Most of them have no idea what’s in there, and the longer they don’t know, the bigger the eventual cleanup.
If you’re not showing your clients this, somebody else will — and they’ll be the ones writing the agent governance policy on your client’s tenant.
Agent 365 isn’t there to add another dashboard to your day. It’s there to stop the shadow AI mess before it starts.
