The command that starts Microsoft Outlook is Outlook.exe. A command-line switch is the addition of a forward slash (/) followed by the switch name and any parameters the switch has.

1. Search for the Microsoft Outlook executable file, Outlook.exe, and make a note of the path to Outlook.exe. For example, the path might be C:\Program Files\Microsoft Office\Office11\Outlook.exe.
2. Click Start, and then click Run.
3. In the Open box, type the complete path you noted in step 1, including the file name. Press the SPACEBAR once, and then type a forward slash mark (/) followed by the switch.
For example, if you want to use the Clean Reminders switch, the command you type in the Open box should look like this:
"C:\Program Files\Microsoft Office\Office11\Outlook.exe" /Cleanreminders
Note Paths that include spaces between words must be enclosed in quotation marks (") and are case sensitive.
4. To run the command, click OK.
