Outlook opens twice

[Jim Peterson]

I have a client that is using Outlook 2003. He is able to open Outlook
multiples times. How do I disable the ability to open outlook twice?

While Yvonne007's advice can limit the number of Outlook processes to one
(most of the time), it won't prevent multiple windows for that single process.
One can always right-click any folder and choose "Open in New Window" to bring
upi what looks like (but isn't really) a second instance of Outlook. There is
no way to disable that, that I'm aware.
