Monitoring event sink # 27 - After you register an event sink on a mailbox store, the Microsoft Exchange Information Store service does not start in Exchange Server 2003

One of my customer had migrated from Exchange server 2000 to Exchange Server 2003, where had an event sink registered on a mailbox store. But his Store.exe (Exchange Information Store service) stops responding for one of the following events: 

• You restart the Microsoft Exchange Information Store service.
• Store.exe automatically starts after a restart of the Exchange Server 2003 server, along with the event logged in the application log;

Event Type: Error
Event Source: Application Error
Event Category: (100)
Event ID: 1000
Date: Date
Time: Time
User: N/A
Computer: Computer_Name
Description: Faulting application STORE.EXE, version Version_Number, faulting module EXOLEDB.DLL, version Version_Number, fault address 0x0002145b. For more information, see Help and Support Center at

• When we troubleshooting the issue, we tried manually start the store.exe, we get the following error message:  System error has Occurred. The process terminated unexpectedly.

When we troubleshooted the issue further we found that the issue occurs if the Criteria field in the event sink has a value of Null. To work around this problem, we tried unregister the event sink and it started working, also we recommended the customer to upgrade with the latest service pack for the Exchange Server 2003.
