How do I turn off automatic grouping for all mail folders

I am using Outlook 2007 and have hundreds of mail folders. Each time I select
a different Folder, Outlook kindly groups them by Date received. I want them
sorted but not grouped. I know I can turn this off for a folder, but I want
to change the default behaviour for ALL my mail folders. I am NOT using
Exchange.
