Exchange 5.5 SP4

Management here would like the ability to automatically delete the contents of users' "Deleted Items" folder on a scheduled, periodic basis.

I looked at "Mailbox Manager" from MS which seems to be a great utility, but it seems to be driven by "message class" versus "message storage location".

Anyone know of any method / technique / utility that can be configured to empty users' Deleted Items folders on a regular basis?

Thanks in advance!
