To use switches, at the Start menu, Run command type:Outlook /switch
Occasionally you'll need to use the full path to Outlook, so the command line looks like:
"C:\Program Files\Microsoft Office\Office11\Outlook.exe " /switch
Note: Paths that include spaces between words must be enclosed in quotation marks (") and are case sensitive.
For your reference here are just some of the most commonly used switches:
