Annoying little beep with new emails

I have outlook 2007 on my laptop and have had this annoying little beep every new email I receive. I found a setting in outlook under notifications that said something about beeps but that didn’t work. I even muted my speakers and that didn’t work. I finally found a SOLUTION in Google somewhere.

 No need to to disconnect the speaker, simply set this values in the registry. Defaults are set to yes and there is no way to turn this into a no from the gui. Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Control Panel\Sound] “Beep”=”no” “ExtendedSounds”=”no”

AND IT WORKS! So now no jumping every time I get an email while concentrating on something else. FYI Thank You!!!
