Not certain about what you're asking. Here are two possible
interpretations of what you asked.
(a) Am I sure that Outlook.exe isn't already running before I trigger
the command? Yes, I'm sure, I checked the process list.
(b) Does the Outlook.exe process run after I execute the command? Yes.
As for disabling the preview pane,I don't need to, or want to for that
matter. I made mention of it in case other customers are experiencing
the same problem.
Cheers,
