I accidentally send e-mails about twice a week because of Outlook's keyboard shortcut for Cmd–Enter sending a message. How do I disable this keyboard shortcut?

Go to System Preferences -> Keyboard -> Keyboard shortcuts -> Application Shortcuts. Now add Outlook/Entourage to the list and make sure that "Menu title" states "Send". After that choose whatever cryptic shortcut you are sure you will never accidentally hit.
Note that you have to quit Outlook, make the change in System Preferences and relaunch Outlook 2011 for the change to take effect.
