I need to prevent any users from permanently deleting any mail items from our Exchange 2000(SP3) server. Currently our users are connecting via Outlook 2000/2003. On a test box, I have already created the registry value HKLM\Software\Microsoft\Exchange\Client\Options "DumpsterAlwaysOn" and set it to 0, but I can still see the "Recover Deleted Items" option for the Deleted Items container (but none of the others). This is a good start, but any savvy users (luckily we don't have many) can still delete an item, empty the Deleted Items container, then choose "Recover Deleted Items" and use the Purge button. There's GOT to be a way of preventing this, I'm just not finding it.
Ultimately, I would like them to still have the ability to recover their deleted items, but not the option to purge them.
I would truly appreciate an answer to this one...
