When you’re having problems with Outlook you may be told to start Outlook using a specific command line switch. To do this: Close Outlook. At the Start menu, Run command (or open the Run command by pressing Windows Key (![windows key icon](http://media.outlook-tips.net/wp/images/2011/05/16x15ximg9D.png.pagespeed.ic.u1GEf897RN.webp "winkey icon")) + R type: Outlook /switch Then click OK to start Outlook.
