Hi Rudolf,
Thanks for your post. Based on my research, it is by design, Windows Backup is not supported for Microsoft Entra ID or Active Directory (AD) users. If you try to run Windows Backup in this scenario, you will receive the error message "This feature is not supported by your organization." Additionally, Windows Backup will not run if your MSA account is blocked by Group Policy. For more information about Windows Backup, see Backup and Restore in Windows.
Best Regards,
Ian Xue
