@Ryan Powell Thank you for reaching out to us, As you mentioned Azure AD Graph will be depreciated by 30th June 2023, Going forward, we will make no further investment in Azure AD Graph, and Azure AD Graph APIs have no SLA or maintenance commitment beyond security-related fixes. Investments in new features and functionalities will only be made in Microsoft Graph.
Azure AD Graph will enter its retirement phase where we will retire it in incremental steps to allow you sufficient time to migrate your applications to Microsoft Graph APIs. The first step in this plan, and at a later date that we will announce, we will block the creation of any new applications using Azure AD Graph.
Microsoft Graph is also more secure and resilient than Azure AD Graph.
Microsoft Graph has all the capabilities that have been available in Azure AD Graph and new APIs like identity protection and authentication methods. Its client libraries offer built-in support for features like retry handling, secure redirects, transparent authentication, and payload compression.
