problem
microsoft outlook 2010 is not appeared at all after startup, cannot be restored, its window position is somewhere not visible
even the new derived windows are not appeared

this works (at least) in versions 2002-2010

solution
To resolve this behavior, delete the relevant registry value and then restart Outlook to recreate the value:

    Click Start on the taskbar, and then click Run.
    Type regedit, and then click OK to start Registry Editor.
    On the registry tree in the left pane, locate the following registry key:
    HKEY_CURRENT_USER\Software\Microsoft\Office\1???\Outlook\Office Explorer\
    In the right pane, right-click the Frame value, and then click Delete.
    Quit Registry Editor.
    Start Outlook
