Running Outlook.EXE as Current User in VBScript

Have a package that contains a VBscript.  Part of the script contains a call to open Outlook, as follows:

WshShell.Run "outlook.exe"

This runs outlook as expected, however, each time upon launch, Outlook wants to create a new account.  Presumably, this maybe cuz the script is running as the system user, and therefore launching Outlook as the system user?

Obviously, we'd like Outlook to launch to run under the logged in user's account.

is this possible?
