Microsoft Outlook Error – “Cannot start Microsoft Office Outlook. Cannot open the Outlook window.”

When going to open my Outlook email client this morning I received the following error message:

“Cannot start Microsoft Office Outlook. Cannot open the Outlook  window.”

Cannot start Microsoft Office Outlook. Cannot open the Outlook  window

This was easily solved by running the following command from the ‘Run’ prompt. *IMPORTANT: Make sure that you have a space between the ‘Outlook.exe’ and the ‘/resetnavpane’ command switch.

“Cannot start Microsoft Office Outlook. Cannot open the Outlook  window

If you are running Windows Vista or Windows 7 you won’t have the ‘Run’ option enabled by default.

“Cannot start Microsoft Office Outlook. Cannot open the Outlook  window

To enable ‘Run’ option go to the ‘Customize Start Menu’ section and check the ‘Run command’ box.

“Cannot start Microsoft Office Outlook. Cannot open the Outlook  window

Everything going well this should fix you’re “Cannot start Microsoft Office Outlook. Cannot open the Outlook  window.” error.

Hi, can anyone help me out there. I am getting frustrated and my computer is about to go for a flying lesson.

My 7 year daughter clicked yes to something the other day but couldnt remember what. Now when I try to open Microsoft Office Outlook I get the message “cannot start Microsoft Office Outlook. Cannot open the Outlook window”.

I saw your response and have tried the above ie. the resetnavpane etc. but now I get a message saying “Cannot start Microsoft Office Outlook. The command line argument is not valid. Verify the switch you are using”.

Does anyone know what this means and how I fix it.

From a really frustrated self-employed secretary who needs her emails. I can access them via another source but its not great. Forgot to mention I am on Windows 7 ultimate.
