MS Outlook Error: Command Line Argument is Not Valid

Asked By ClairaN 0 points N/A Posted on - 10/04/2011

Hello, Techyv. I need you help solving an issue that I can't seem to figure out myself.

 I can't start my Microsoft Office Outlook.  When I click on the desktop folder I get the above error message.

I tried to access Microsoft Office Outlook through the control panel, but I get the same error message. 

Does anyone know how I can fix this?  It was working fine yesterday. 

Why is it doing this all of the sudden? 

Any advice would be appreciated.

Thank you!

Error:

Microsoft Outlook

Cannot start Microsoft Office Outlook. The command line argument is not valid .

Verify the switch you are using.

MS Outlook Error: Command Line Argument is Not Valid

I experience this error multiple time when I started working as an IT Support.

At first I don't seem to know what to do but now I do. I have two different solutions which might help you.

Before doing, don't forget to contact your system administrator first if you have one.

Restarting:

1. One of the first thing I do is restarting my computer in the event that this error for excel occurs. This is not a hard thing to do and it is just the basic. 95% of the time it works for me it should work for you too.

Reinstalling:

1. You then try uninstalling the Outlook and reinstall it again once you have removed it. Just simply go to the Control Panel, and then choose Add Remove Programs for XP or Uninstall a Program for Windows 7 and Basic.

2. Look for it and the select it. Then start removing it.
