A simple fix to open the broken Outlook Window

I was on holiday today but a call from a friend had me in PC repair mode. The problem was Outlook 2007, on a home PC so no Exchange, refusing to start with the message:

"Cannot start MS Office Outlook. Unable to open the Outlook window”

This one was new to me so I ran Office Diagnostics to check the install. That was clean so a bit more research was required to find this simple fix. Just fire up Outlook with the command:

Start > Run > Outlook.exe /resetnavpane

After that Outlook started normally from the icon, back to the holiday!
