Open outlook with the /resetnavpane switch:

Close Outlook. At the Start search field on Vista or Windows7 Start menu or in the Start menu, Run command (Windows key + R), type

outlook.exe /resetnavpane

Then press Enter (or OK button) to restart Outlook.

Note: Make sure there is a space between the words.
