Unity Connection is configured with system-wide mailbox size quotas that can be customized to set restrictions on the send or receive of user voice messages. For more information on mailbox quotas, see the Message Storage, on page 109 chapter. • Message Aging Policy: When a mailbox store is created, maximum amount of disk space is created for the user voice messages. To maintain the allocated disk space within the specified mailbox quota, Unity Connection provides message aging policies. The rules apply on users mailbox and ensure that disk space for where voice messages are stored do not fill up. The state of the messages is changed when the aging policy is active. For example, new message moves to saved state and saved to deleted in the specified period of time. For more information on message aging policy, see the Message Storage, on page 109 chapter. • Unified Messaging Service: Unity Connection supports Unified Messaging Service (UMS) that integrates voice messaging with your email account, allowing you to store voice messages in your mailbox along with your email.
