Help please.

Our school district has upgraded to Outlook 2007. We have a program that
emails student grades to parents. It interfaces with Outlook to do this. It
still works, but Outlook keeps popping up with a "suspicious program is
trying to send emails" warning. There is a setting in Outlook's Trust
Center, in the Programmatic Access tab, to turn that option off. But it's
greyed out! The only solution I've found so far is to give users
administrative access, which is what we're trying to avoid these days. Does
anyone know of a different setting or reghack that can re-enable that
option?

Thanks,
Sir Timbit
