This began a few weeks ago.
When undeliverable email is returned to me, a notice is placed in the notification area of the taskbar for just a very few seconds. There is hardly time, before it fades away, to click the notice to see to whom the email was sent. The email itself is not placed in the inbox as in the past.

Does anyone know what caused this change and what needs to be done to have the returned mail placed in my inbox.

Thanks
