I can't toggle between Outlook's windows. When I click the Windows menu item, there is no sub-menu item to toggle to the next window. I only see the names of the windows that are active with no keyboard shortcut beside them. When I use [command + tilde] I hear a bell ringing (clear indication that I've done something wrong) but the windows do not toggle. From what I've read, this should be a basic command. What am I missing?

FYI - I use keyboard shortcuts in other applications all the time. I have also tried every combination of command, function, option, control and shift along with TAB and tilde.
