MSExchange Anti-spam Update

Alert Type


Rule Path

Microsoft Exchange Server/Exchange 2010/Common Components/Hub Transport and Edge Transport/Agents/Common

Rule Name

The installation of the Microsoft Exchange Anti-Spam Update service failed with an error.


This Error event indicates that an anti-spam update could not be installed because of the error specified in the event description. This event occurs when anti-spam updates are not loaded.

This may be caused if either of the following conditions is true:

  • There are Internet connectivity failures.

  • There is an HTTP proxy failure or misconfiguration.

User Action

To resolve this error, follow these steps:

  • Verify Internet connectivity. Check to see if you can successfully access the Internet from the Windows server.

  • Verify the correct HTTP proxy settings. Verify that your proxy server is not blocking access to the Windows Update site.

  • Review the WindowsUpdate.log file for information that could indicate the cause of the problem. By default, WindowsUpdate.log is located in the C:\Windows directory on the Windows server. If needed, you can configure the WindowsUpdate.log for extended logging by enabling verbose logging. To turn on verbose logging, add the following registry key with two values:

    Copy Code
    Value name: Flags
    Value type: REG_DWORD
    Value data: 00000007
    Value name: Level
    Value type: REG_DWORD
    Value data: 00000004
    Note   This registry key turns on extended tracing to any attached debuggers.

    Important    Incorrectly editing the registry can cause serious problems that may require you to reinstall your operating system. Problems resulting from editing the registry incorrectly may not be able to be resolved. Before editing the registry, back up any valuable data.
