Outlook 2007 Sound

[Davet102]

I'm running Vista and Office 2007.

I would like to add/change sounds when email arrives.

I cannot find it in the Ourtlook program.

I have gone to control Panel and made a change to the "New Mail" sound but I
am not hearing it.
I'm using Wav files so they should work.

What am I missing or doing wrong??

Thanks

Bob
