Authorization_RequestDenied

Insufficient privileges for the Graph request

Answer: Microsoft Graph understood the request but the caller does not have effective permission to perform it.

Fix it, then prove it

Use the error record as the starting point; use tenant evidence to confirm the actual cause.

A permission listed on an app registration is not effective until the correct consent and token context exist.
The token is missing, expired, for the wrong audience, or contains the wrong delegated/application permission type.
Consent, Microsoft Entra role, licensing, resource ownership, or endpoint-specific authorization is still insufficient.

Compare the endpoint's least-privileged permission with the token's scopes or roles.
Confirm admin consent was granted when the permission requires it.
Check directory roles, resource-specific authorization, and application-versus-delegated context.

Acquire a new access token after permissions or consent change.
Confirm delegated permissions appear in scp or application permissions appear in roles, and that aud targets Microsoft Graph.
Repeat the exact HTTP method and endpoint and confirm the response no longer returns the same request ID/status.

The failure persists after the documented prerequisites and a new authentication/session attempt.
Multiple users, apps, devices, or networks show the same error, suggesting tenant policy or service scope.
You can provide the exact UTC time, tenant, application/resource, correlation or request ID, and sanitized logs.

Inspect the active Graph PowerShell context

Get-MgContext | Select-Object ClientId,TenantId,Account,AuthType,Scopes

Read-only. Confirms tenant, auth type, and delegated scopes. For app-only tokens, also inspect the token roles claim.
