vba - public folders - permissions

Hi there,

I want to lock down the public folders in Outlook, so no one can
modify them/their contents - i want changes to be made via an Access
application I have.

However, if i lock down the folders, then ACCESS can't get at them...

is there a way to give an active directory account permissions to the
public folder(s), and then have the MS Access application
"impersonate" that user, so it can modify the contents?

Any help appreciated, hope it's clear what i am trying to do.

Thanks, Kevin
