This section describes basic information about synchronous, asynchronous, and system events.
Synchronous Events
Synchronous events are called twice, once in the begin phase and again while the transaction is being committed or aborted. The IExStoreSyncEvents Interface has two methods, as described in the following table.
| Event | Description |
|---|---|
| OnSyncSave Method | Called when an item is saved to the Exchange store, but before the changes are committed. |
| OnSyncDelete Method | Called when an item is deleted from the Exchange store, but before the delete is committed. |
Note Moving an item triggers both the OnSyncDelete and OnSyncSave events.
Asynchronous Events
Asynchronous events occur after the item is committed to the store. The IExStoreAsyncEvents Interface has two methods, as shown in the following table.
| Event | Description |
|---|---|
| OnSave Method | Called when an item is saved to the store after the changes are committed. |
| OnDelete Method | Called when an item is deleted from the store after the delete is committed. |
Note Moving an item triggers both the OnDelete and OnSave events.
System Events
The IExStoreSystemEvents Interface has three methods, as described in the following table.
| Event | Description |
|---|---|
| OnTimer Method | Called after a specified period of time. |
| OnMDBStartUp Method | Called when the Exchange store MDB is started. |
