We have Exchange Server 2003, and we have a general public email box that gets a massive number of emails each day. We would like to setup the email box so that it automatically deletes any messages older than 30 days. (purge, not move to deleted items). We also want to have this done by the server and not dependent on any single client to connect in for this rule to activate.
I've been searching around Experts-Exchange and I've found a few messages about the Recipients Policy settings, but that seems to be something that applies system wide, not just a single mailbox. Also the Client generated, server side rules, only seem to work on arriving messages, and not to messages that have been sitting around in the INBOX for 29+ days.
