It is temporary. We wanted to flush everyone's cache as we migrate Exchange servers. Once is enough that's why I included that statement.
What does the 0 in Quit 0 do?

Another question for your guys if you don't mind. I'm trying to make this registry change for everyone as in the past we disabled the autoname check / caching features but want to reinable it. Here's the entry.

[HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Outlook\Preferences]
"ShowAutoSug"=-

What's the best way to do this? You mentioned a way to flag it so it only runs once...

Thanks,

John
