I set deleted item retention, on both the server side and client side. It seems that it is not working. THe "cleanup agent" doesnt seem to be doing it's job. This is Exchange 2007 with SP1. Some mailboxe users have over 4000 items in their mailboxs. Other user policy has the default of 14 days, but also have thousands of items in their mailboxes.
I just configured a script to backup all mail to PSTs, but i would like to reduce the deleted items for backup.
