By default, applications created after August 31, 2024, will receive a 403 Unauthorized error when making requests to Azure AD Graph APIs unless explicitly configured to allow extended access. For applications created before this date, extended access must be configured by February 1, 2025 to continue using Azure AD Graph. This access is only valid until June 30, 2025, after which all requests to Azure AD Graph APIs will be blocked, regardless of configuration.
I understand i need to remediate and use Microsoft Graph however can I still extend in the meantime?
No, you can't extend Azure AD Graph APIs at this point. The extension must be configured by February 1, 2025, and it cannot be applied afterward.
In your current scenario, you’ll need to start using Microsoft Graph now, as the extension for Azure AD Graph access was not configured. If the extension had been set up before the deadline, you would have been able to continue using Azure AD Graph until June 30, 2025.
