Outlook 2007, starts at boot, minimized: suddenly, as of 2 weeks ago, when I click on the taskbar icon (Outlook already started but minimized) what opens on screen is a tiny "window" the size of the close-minimize-restore buttons.

I then have to move it down the screen, and drag the borders to bring it to full size, or, sometimes, clicking on the restore button maximizes the tiny window: then, for days, it starts either the same way or in some other small size, not the same as I left it.

I would appreciate suggestions on how to repair this particular example of Outlook not remembering its setting?
