M365 Copilot Agent now support multiple users

Microsoft 365 Copilot agents now support multiple owners, enabling collaborative management and reducing dependency on a single creator. This update, rolling out worldwide in August 2026, allows equal editing permissions for all owners, improved sharing controls, and organization-wide agent publishing, with some limitations on group ownership.
