Is it possible to create scheduled tasks for specific mailboxes rather than for the entire post office? I have a handful of users who account for over 90% of my post office's usage. It sounds like I'm finally getting support to take an enforcement stand to do something about it. I'd like to create a message expiration rule that would only affect those few mailboxes rather than the entire post office. Is it possible?

On a side note, I do have archiving in place to archive all user messages after a year, and the messages still aren't deleted from GW for another year after they have been archived "for convenience." For these users it sounds like we're considering tightening up the period of time from archiving to removal from GW, but only if I can automatically isolate them. Running a manual GWCheck on when I set a personal reminder won't cut it.
