How To User Mailbox Management Policy

1. Define a policy in "Recipient Policies" container. Make sure you have correct filters and actions defined.
2. Apply the policy immediately/manually or wait for RUS kicks in overnight
3. Define a Mailbox Management schedule on *ALL* involved servers
4. At this point, you can wait for the scheduled Mailbox Management process to launch or manually run it by selecting ?Start Mailbox Manager?

Note: Mailbox Management policy is not the same as System Policy that applies to either mailbox stores or servers. Mailbox Management policy is defined in Receipient Policy container while System Policy is defined under server object.
