please help us verify two possibilities to narrow down the issue:
1. Check if users are already in the list
Our system logic hides users who are already added to the backup protection. Please check your current user list—if those 2 licensed users are already there, they will not appear in the “Add users” sync list again.
2. Verify Account Permissions
Please ensure that the account used for the integration has sufficient permissions to access the directory. If the API permissions in the Microsoft Entra (Azure) portal lack the necessary “Admin Consent,” the user list may return empty.
