Notes
If no ExpirationAge value is specified, notifications never expire. Notification Services continues to attempt delivery of all notifications until the retry schedule is exhausted.
During delivery, Notification Services ignores any notifications that have expired per the ExpirationAge value.
The format of the XML duration data type is PnYnMnDTnHnMnS. For more information about XML data types, see Primitive XML Data Types in the Microsoft MSDN® Library.
Exemple
The following example shows how to set an expiration age of one hour and thirty minutes. If notifications are not sent within this time, Notification Services ignores them for all future delivery attempts, regardless of the retry schedule.
<ExpirationAge>PT01H30M00S</ExpirationAge>
