Your organization's IT department or Office 365 Global Administrator must handle the service request through the official admin portal.

Identify your global administrator

Locate the IT contact or Office 365 Global Administrator within your organization who manages your Microsoft licenses.

Request a service ticket

Ask the administrator to log into the Microsoft 365 admin center and navigate to the Support section to open a formal service request for Copilot Studio.

Provide configuration details

Supply your administrator with the exact error message you received, the JSON file format you attempted to upload, and the steps you took when creating the agent.

Engage reseller support if applicable

If your organization purchased Microsoft 365 through a third-party vendor, advise your administrator to contact the reseller's support team directly for quicker resolution.
