Is there a way to prevent certain users from emptying their Trash? We have a legal need to retain all of their email for a specific amount of time.

I found this in another thread, but it's not working for me. I can still empty individual items.

>>Create a bogus trusted app in C1 that "provides message retention services",
in the client preferences of the user in the envrioment, slect the retention
tab and enable that bogus gw trusted app you created in C1, presto that user
will not be able to empty their trash.<<

I created the Trusted app, set it for myself, waited about 15 minutes, but still not working.

We may end up using a third party app (Retain or ?), but trying to find something built in.
