Enough detail is available to trust this assessment.
Assessment Reasoning
The feature is now generally available, allowing users to send messages from configured aliases in Exchange Online. This removes the need for manual workarounds and provides flexibility in identity management. Admins need to review configuration options in PowerShell or the Exchange Admin Center, which introduces moderate setup work. User impact is noticeable due to the new sending option in mail clients, while urgency is moderate since the capability is available immediately but not mandatory.
