Microsoft.Graph.ServiceException - AuthenticationError

Question

I have purchased the SPO license, but when I try to access OneDrive through the Graph API, I encounter the following error:

HResult=0x80131500

Message=Code: AuthenticationError

Message: AADSTS500014: The service principal for the resource is disabled. This indicates that a subscription within the tenant has lapsed, or that the administrator for this tenant has disabled the application, preventing tokens from being issued for it.

Please help me resolve this error.

Hi iTech Software Group,

Thanks for reaching out to Microsoft!

To resolve this issue, first ensure that your subscription is active and compliant, as a lapsed subscription could be the cause.

If you already have an active, compliant subscription and the application is enabled for user sign-in, I will also recommend trying these steps:

• Verify if the application is enabled in the Entra portal. Make sure that the application is not disabled by the administrator. You can check this by going to the "App registrations" in the portal.

Ensure that the necessary permissions are granted to the application.

If the service principal is disabled, you can re-enable it using Microsoft Graph. Send a PATCH request to /servicePrincipals/{servicePrincipalObjectId} with the following payload:

{
    "accountEnabled": true
}
 

Hope this helps.
