For some reason I can't understand, Outlook (2011 for Mac, using OS X 10.8.4) will not play my sound sets, even though I've installed them properly inside the Microsoft User Data-->Outlook Sound Sets folder. In the "Notifications and Sounds" preference panel, I can click on the selected sound set (default or my custom sound set) and it will play the welcome sound. But when I click on any of the subsounds (New Message, Message Send, etc.) it will not play those. (There is a 'soundset.plist' in place inside each sound set folder.)

Screen shot here.


Any help would be greatly appreciated. Thank you.
