Explanation:
Microsoft Exchange 2013 Safety Net is a new feature in Exchange Server 2013 that prevents data loss by maintaining a queue of successfully delivered messages.
The Exchange 2013 Safety Net is essentially a delivery queue that exists on each Exchange 2013 mailbox server. Each time a message is delivered to a database, a copy of that message is held within the Safety Net. The message copy remains in the Safety Net until its expiration date, which is determined by the administrator.
