Disabling the annoying notice when new e-Mail arrives in Outlook 2007

Just for my own reference, here is how to disable the annoying sound and desktop alert in Outlook 2007 when new e-Mail arrives (Hint: e-Mail is not Instant Messaging, there is no need to be interrupted immediately by new mail, if it is important, people can just use IM):

Tools => Options => Preferences => E-mail Options => Advanced E-mail Options => When new items arrive in my Inbox => Untick all 4 options
