SYMPTOMS
In an environment that is running Microsoft Exchange Server 2003, you may randomly experience the following symptoms:  The server that is running Exchange Server experiences up to 100 percent CPU usage. In this situation, the Store.exe process uses most of the CPU resources. Many e-mail messages are queued in Exchange Server. Microsoft Outlook clients may stop responding (hang). Alternatively, Outlook clients may receive the following error message:

Error 0x8004060c





CAUSE
This problem may occur if an Outlook client tries to download an incorrectly formatted e-mail message. In this situation, the download operation fails. However, the download process does not exit. Therefore, the corrupted download request generates many flush requests to Exchange Server.
