Outlook 2003 Command Line Switches

Outlook 2003 is usually installed in C:\Program Files\Microsoft Office\OFFICE11
Open a CMD window, navigate to that path, and run Outlook.exe with the appropriate switch.

To use switche via the Start button, 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:
