To apply a recipient policy:
Note When a new mailbox recipient policy is created, Recipient Update Service assigns a unique ID to member mailboxes. This ID associates the mailboxes to the policy, which is how Mailbox Manager knows which mailbox recipient policy to apply to a given mailbox. If you modify a mailbox recipient policy so membership is modified, the Apply this policy now command immediately associates new mailboxes to the policy without waiting for Recipient Update Service to run. However, this command does not affect mailboxes that were previously members of the policy but are no longer members. These mailboxes will continue to be affected by Mailbox Manager until the next time Recipient Update Service runs and removes them from the policy. Recipient Update Service runs automatically and membership will always be updated, but administrators should know it is possible that, depending on how long it takes Recipient Update Service to update policy information, Mailbox Manager may temporarily process mailboxes that are no longer included in a mailbox recipient policy.
