The Microsoft Exchange Information Store service may crash when it processes a rule that has a NULL value for the Action setting (903924)


The information in this article applies to:

  • Microsoft Exchange 2000 Server
  • Microsoft Exchange 2000 Enterprise Server

SYMPTOMS

When a Microsoft Outlook client computer receives an e-mail message, the e-mail message triggers Microsoft Exchange 2000 Server to process the rules that have been configured for that mailbox. When the Microsoft Exchange Information Store service processes a rule that has a NULL value for the Action setting, the Information Store service may crash.

CAUSE

This problem occurs because the existing code cannot logically determine whether an action is NULL. You should not use a NULL value for the Action setting in a rule.
