Cannot start Microsoft Outlook. Cannot open the Outlook window.

This morning I encountered this error when I tried to open Outlook. "Cannot start Microsoft Outlook. Cannot open the Outlook window." Turns out, all you need to do is go to run and type or paste "outlook.exe /resetnavpane".

• In XP "run" is located at Start > Run...
• In Vista and Windows 7 it is combined with the search box that is at the bottom of the menu that pops up when you click on the round glow ball that took the place of the Start button.
