AI agent ownership change

Hello,

Changing the owner of an agent in the Microsoft 365 Admin Center is considered a governance action and requires either the AI Administrator or Global Administrator role.

I haven't found any informations indicating that the Application Administrator role is required for the "Assign new owner" action. 

One detail that stands out is the message shown in your screenshot: "Management of this app requires a different set of admin permissions."

This could indicate that the operation is being blocked at the level of the underlying application associated with the agent rather than at the agent object itself.

What role is currently assigned to your account ? 

And whether the agent was bulding with Copilot Studio or Agent Builder ?

If your objective is to transfer ownership of the agent, the first thing you could verify is that your account has either the AI Administrator or Global Administrator role, as these are the roles for this operation.

Hope this helps
