We recently implemented an e-mail rention policy. We instructed the server to delete all e-mails prior to 2007, however the send recieive the next morning is painfully slow. We have aprox 300 mailboxes. It is almost like the client is resynching the entire cached mailbox. This latency occurs on newer mailboxes as well that would have had nothing to be purged. Server utilization is fine, network is not saturated, what am I missing?
