If you change the retention time of a quarantine, only new messages will have the new expiration 
time.

If the system clock is changed, messages that should have expired in the past will expire at the next 
most appropriate time. 

System clock changes do not apply to messages that are in the process of being expired. 

The default action is performed on messages in a policy, virus, or outbreak quarantine when any situation 
described in 

, occurs. 

There are two primary default actions:

Delete—The message is deleted.

Release—The message is released for delivery.
