Cannot start Microsoft Outlook. Cannot open the Outlook Window.

If you’re getting this error message pop up when starting Outlook, try the following fix:

Windows XP

Start – Run; Outlook.exe /resetnavpane

 

Windows Vista, Windows 7

Start – tyoe outlook.exe /resetnavpane

I also found a reference to the same error on the MS knowledgebase, however the fix was to remove the profile and recreate it, which didn’t help fix the error.
