Outlook Exchange Accounts Optimizer ensures your on-line Exchange mailbox never gets full.This utility automatically moves messages from your Outlook Exchange account to a replicated structure within Outlook local folders. With OEAO you can filter messages by age (email older than X days), by date range or by From field. Outlook Exchange Accounts Optimizer can handle multiple accounts and be set to run automatically.
If you want to test the rules you setup you can run OEAO in "Simulation Mode" and see how many messages will be moved based on the rules you setup.
