How to use Outlook's Command line switches

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) + R type:

Outlook /switch

Then click OK to start Outlook. (There is a space between outlook and /.)

This screenshot shows how you enter it, using the /cleanreminders switch as an example.

command lines

Occasionally you'll need to use the full path to Outlook, then the command line looks like this:

"C:\Program Files\Microsoft Office\Office11\Outlook.exe" /switch

Notes:

Before using a command line switch, you need to close Outlook and verify it's closed in Task Manager's Processes tab.

Paths that include spaces between words must be enclosed in quotation marks (") and are case sensitive.

If you use Vista or Windows 7, you can type the command line in the Start Search field on the Start menu.

You'll need the full path if you  want to create desktop shortcuts using a switch, such as to open Outlook to a specific folder:

"C:\Program Files\Microsoft Office\Office11\Outlook.exe" /select outlook:calendar
