Is there a way to set storage limits on mailboxes so that when users access there email a message will appear alerting them about the size of there mailboxes? What I want to do is set storage limits, but not right away. I want to give them time to reduce their mailboxes on their own before they stop receiving messages. I want to give them warnings about their mailbox size before fully applying the storage limit. We use exchange server 2007 with outlook 2000 and 2007 clients.
