Rule Name

The Exchange store can't create any more MAPI-named properties.

This Error event indicates that a user could not add a new MAPI named property because the number of MAPI-named properties has reached the configured limit. Review the event description for information that is specific to your environment.

The configured default limit is 16 x 1024 (16 kilobytes). This limit is set to reduce the ability of a malicious application to make the database inoperative by exhausting the 32 kilobytes available for MAPI named properties.

To resolve this problem, do one or more of the following:

  • Review the Application event log for this event to determine which specific applications are trying to exceed the maximum quota.

  • For more information about this limit and how to increase the value, review Microsoft Knowledge Base article 820379, How to configure quota settings for named properties and for replica identifiers in Exchange Server 2003 and in Exchange Server 2007. Be aware that the maximum value is 32 KB.

    Note   Named Props Quota is the registry value for MAPI named properties.

  • Resolve your issue by using self-support options, assisted support options, and other resources. You can access these resources from the Exchange Server Solutions Center. From this page, click Self-Support Options in the navigation pane to use self-help options. Self-help options include searching the Microsoft Knowledge Base, posting a question at the Exchange Server forums, and other methods. Alternatively, in the navigation pane, you can click Assisted Support Options to contact a Microsoft support professional. Because your organization may have a specific procedure for directly contacting Microsoft Product Support Services, be sure to review your organization's guidelines first.

If you are not already doing so, consider running the Exchange tools, which have been created to help you analyze and troubleshoot your Exchange environment. These tools can help make sure that your configuration aligns with Microsoft best practices. They can also help you identify and resolve performance issues and improve mail flow. To run these tools, go to the Toolbox node of the Exchange Management Console. To learn more about these tools, see Managing Tools in the Toolbox.
