"DESCRIPTION 1"="By default, the Desktop Alert Setting inside Outlook allows a maximum of 30 seconds through the normal options dialog (Tools -> Options -> Email Options -> Desktop Alert Settings)."
"DESCRIPTION 2"="However, Outlook is able to keep the Desktop alert for a much longer period of time. Simply enter how long the desktop alert should stay on your screen inside the box (in seconds)."
"DESCRIPTION 3"="Note: Even if you have configured a bigger value as 30 seconds here, the options dialog of Outlook will still show "30 seconds" although a much higher value will be in effect."
