I am running Window XP Pro SP 3 and Outlook 2003. I want to change my email notification sound so I did so in Windows and can play it back just fine (in Control Panel) after I change it. When I get a new email, I hear nothing. I tried to rename my desire WAV file to the default Windows XP Notify.wav and it still plays, but I hear nothing when I get a new email in Outlook. I tied to create a new scheme and it still does not work when a new email comes in. If I put the original Windows XP Notify.wav back, it plays manually but not when I new email comes in. I know this worked when I was running Windows 2000, but that was a long time ago and I just changed it in XP for the heck of it. I don't use my speakers that much, so it has probably been like this for a long time and I just noticed it when I wanted to change this particular sound. The other Windows sounds seem to work okay except this one. Any ideers out there?
