To get the main Outlook window back to full size, find and delete the Frame value under HKEY_CURRENT_USER\Software\Microsoft\Office\xx.0\Outlook\Office Explorer, where xx is your version of Outlook.

If you like your windows arranged in a specific side and position on the desktop, you'll want to close all other windows before using these commands.

Changing the screen resolution may have caused it, but you can fix it without changing display settings. The usual cause is because the window is pushed off the edge of the screen. Clicking Restore seems to minimize the Window, not restore it. This user's problem was that Outlook is either minimized or maximized.
