System events give timed notifications or notify an event sink that databases have started up or shut down.

There are three system events that fire in the Exchange store: OnTimer, OnMDBStartUp, and OnMDBShutdown.

Name When the event fires


After a certain period of time.


When a store is started.


When a store is shut down.

Data in a store is housed in files with the .mdb extension. Although these events contain "MDB" in their names, they refer to a store.
