We need to push Push Pop up notifications for ex: “urgent message to warn users” and also generate a report on the success rate as to how many users in the network received it and read it, how many users did not receive it or did not read it.
Microsoft has suggested to use SCCM Power Schell scripting to send Client notifications with close button to confirm receive.
Is there any other way of accomplishing it through SCCM without any customization?
Have you considered pushing a VBScript to all clients which displays the message? If the user clicks "OK" to say they've read and understood the message then it could exit with a return code of 0, otherwise it could return a 1. It's then trivial to report each computer's success result in SCCM.
