Starting February 1, 2025, Microsoft has retired Azure AD Graph. As a result, any application relying on Azure AD Graph will be unable to make requests to its APIs, including all versions of Veeam Backup for Microsoft Azure version 5a and older.
For more information, see this Microsoft announcement.
A fix will not be released for older impacted versions of Veeam Backup for Microsoft Azure, as they reached End-of-Fix when subsequent versions were released.
Customers are advised to upgrade to Veeam Backup for Microsoft Azure version 6 (build 6.0.0.234) or newer, as these versions were designed with the Azure AD Graph API deprecation in mind and now leverage the preferred Microsoft Graph.
Veeam Backup for Microsoft Azure v6 was released alongside and is deployed by Veeam Backup & Replication 12.1 (released on 2023-12-05).
Veeam Backup for Microsoft Azure v7 was released on 2024-07-02 and is deployed by Veeam Backup & Replication 12.2, which was released 2024-08-28.
