Identified:

Unless you are using a third-party app on your tenant that is configured with Azure AD Graph API, you likely will only see Microsoft apps listed on your tenant regarding this notice, such as “Microsoft Office”. If you do have a third-party app listed, you will need to work with that vendor who supplies that app to confirm they have an upgrade available to Microsoft Graph API. If you only see “Microsoft Office” as the listed app, see the information below:

Please see the following Microsoft blog for full details:

Action required: Azure AD Graph API retirement | Microsoft Community Hub

Statement from Microsoft Blog -

Some of the service principals using Azure AD Graph in your tenant may be provided by Microsoft. Most of these have an update available that uses Microsoft Graph, instead of Azure AD Graph APIs, such as:

• Azure AD PowerShell: AzureAD PowerShell is deprecated and will be retired soon. You should migrate to Microsoft Graph PowerShel SDK
• Azure CLI: Microsoft Graph migration
• Azure PowerShell: PowerShell Gallery | Az 12.4.0
• Visual Studio: Visual Studio 2022 version 17.7 Release Notes

Some Microsoft applications, including Microsoft Office, Microsoft Visual Studio Legacy, and Microsoft Intune, do not yet have an update available without Azure AD Graph API usage. For these, we will provide future Azure AD Graph API retirement blog updates when a replacement version is available. These apps will be granted extended access for Azure AD Graph and sufficient time will be given to update the applications when an update is made available.

Resolved: This incident has been resolved.
