XADM: Removing and Re-Installing the Event Service (192174)

SUMMARY

In certain cases you may find it necessary to remove and re-add the Event Service service. The following Event IDs may be seen in these cases.

One series of events that might occur, requiring the removal and reinstallation of the Event Service is:

   Event ID   : 0
   Source     : MSExchangeES
   Type       : Informational
   Category   : General
   Description: The Microsoft Exchange Event Service (5.5.1960.3)
                Started successfully.

   Event ID   : 5
   Source     : MSExchangeES
   Type       : Error
   Category   : General
   Description: An unexpected MAPI error occurred. Error returned
                was [0x80004005].

   Event ID   : 1
   Source     : MSExchangeES
   Type       : Informational
   Category   : General
   Description: The Microsoft Exchange Event Service stopped successfully.

Before removing the Event Service as a solution, verify that this server is a public folder server. If the server is not a public folder server, the Events Service will not start. For additional information, please refer to the following article in the Microsoft Knowledge Base, which explains this requirement in more detail:

MORE INFORMATION

Removing the Event Service and re-adding it does not require that you stop any other Exchange Server services or reboot the server.

WARNING: Removing the Event Service will cause you to lose all scripts installed on the server and all permissions assigned on the Eventconfig_<server name> for the server.

Steps to Remove Event Service

You will need your Exchange Server CD.

Run Setup from the Exchange Server CD.
Click on the Add/Remove Button from Setup program.
Select Exchange Server, and click on the Change Option button.
Clear the Microsoft Exchange Event Service option.
Click Ok, then click Continue, and click Yes to remove one component.
Check the services under Control Panel Services and be sure the Event Service has been removed.
Re-run the Exchange Server Setup, following the same steps, and select the Microsoft Exchange Event Service.
Reapply any service packs that were installed on Exchange Server prior to the removal of the Event Service. This, however, requires the stopping of services by the service pack installation.
