Step-by-step guide on how to register store event sinks

Per KB, Before you use regevent.vbs to register the event sink VB script, you need to register a new COM+ application on the Exchange server to properly execute script-based store events. Please follow the steps below:

1. To start the Component Services console, click Start, select Programs, Administrative Tools, and Component Services.
2. In the Component Services snap-in, expand the list in the following order: Component Services, Computers, and My Computer.
3. Right-click COM+ Applications in the left pane, and select New and Application.
4. Click Next and then choose the "Create An Empty Application" button.
5. Enter ScriptEventSink as the name for the new application.
6. Confirm that the Server Application radio button is selected and click Next.
7. Click Next and click Finish.
8. Select a user that will have owner permissions for the application you are creating, or choose the current user by selecting "Interactive User - The Current Logged On User" radio button. Note If you choose Interactive User, make sure the account that you are currently logged on with has one of the following permissions:
• Explicit "Full mailbox access" right on the mailbox you plan to publish the sink to
• Explicit Allow for the "Receive As" right on the mailbox store
9. Open the newly created COM+ Application you just created, right-click on the Components subfolder, and choose New and, then, select Component.
10. Click Next, then choose Install New Component(s).
11. Browse the file system and select \Exchsrvr\Bin\exodbesh.dll. Click Next and Finish.

After registering the new COM+ application, you need to write the event sink VB script file. Here is a sample event sink that does nothing but log its' existence:

  <SCRIPT LANGUAGE="VBScript"><br>Option Explicit<br>Public Sub ExStoreEvents_OnSave(pEventInfo, bstrURLItem, lFlags)<br>  LogFile "ExStoreEvents_OnSave"<br>End Sub<br>public Sub ExStoreEvents_OnDelete(pEventInfo, bstrURLItem, lFlags)<br>   LogFile "ExStoreEvents_OnDelete"<br>End Sub<br>Public Sub ExStoreEvents_OnSyncSave(pEventInfo, bstrURLItem, lFlags)<br>  LogFile "ExStoreEvents_OnSyncSave"<br>End Sub<br>Public Sub ExStoreEvents_OnSyncDelete(pEventInfo, bstrURLItem, lFlags)<br>   LogFile "ExStoreEvents_OnSyncDelete"<br>End Sub<br>public Sub LogFile(MyString)<br>   Dim fso<br>   Dim txtfile<br>   Set fso = CreateObject("Scripting.FileSystemObject")<br>   Set txtfile = fso.OpenTextFile("c:\LogFile.log", 8, True)<br>   txtfile.WriteLine (MyString)<br>   txtfile.Close<br>End Sub<br></SCRIPT>

We assume that the sink is now saved in the testscript.vbs., you can now register this event sink VB script using the following steps:

1. Click Start, select Run, and type "cmd" (without the quotation marks) to enter the command prompt.
2. Change the directory to \Exchsrvr\Bin and type the following 2 commands: regsvr32 exodbesh.dll regsvr32 exodbprx.dll
3. Copy the regevent.vbs (located in the \Program Files\Exchange SDK\SDK\Support\OLEDB\Scripts directory.) and the event sink VB script files onto the root of the C drive.
4.

Start the command prompt, and change to the directory of C:\. Type the command to run the regevent.vbs. The following command is one example: cscript regevent.vbs add "onsave;ondelete" ExOleDB.ScriptEventSink.1 "file://./backofficestorage/contoso.com/MBX/smith/inbox/testsink" -m deep -file "c:\testscript.vbs" Note:

  • This command is used to register the event sink VB script named testscript.vbs in the Inbox of the mailbox named smith.
  • In the command above, you replace contoso.com with the default domain name referenced on the "Local path" field in the Virtual Directory tab of the Exchange virtual directory properties in the Internet Information Services snap-in.
