SYMPTOMS

In an Exchange Server 2007 environment, a named property that is used to map X-headers during a message is processed at the mailbox store level. However, the named property has a size restriction. When many X-headers are promoted to named properties and the quota limitation is reached, unexpected problems occur. For example, messages from a specific domain cause the following NDR:
#550 5.2.0 STOREDRV.Deliver: The Microsoft Exchange Information Store service reported an error. The following information should help identify the cause of this error: "MapiExceptionNamedPropsQuotaExceeded:16.18969:C0000000
When this issue occurs, the following event message is logged in the Application log on the Exchange server.
Event Type: Error
Event Source: MSExchangeIS
Event Category: General 
Event ID: 9667
Description:
Failed to create a new named property for database "<Storage Group name>\<Mailbox Store name>" because the number of named properties reached the quota limit (8192).
User attempting to create the named property: "<name>"
Named property GUID: <GUID>
Named property name/id: "<ID>" 
If you check the previous application event logs, you may find that many 9873 events that resemble the following message are logged:

RESOLUTION

To resolve this problem, install Update Rollup 8 for Exchange 2007 Service Pack 1.

For more information about Update Rollup 8 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic:
Description of Update Rollup 8 for Exchange Server 2007 Service Pack 1
For more information about how to obtain the latest Exchange service pack or update rollup, see the following Exchange Help topic:
How to Obtain the Latest Service Pack or Update Rollup for Exchange 2007
Note After you apply the hotfix to the Exchange server, the Exchange 2007 server does not promote new X-headers from unauthenticated submissions, embedded messages, and journal messages. However, the X-headers requests that are submitted by authenticated clients can be still promoted. Also, later unauthenticated submissions will still process the values of X-headers because any subsequent messages that include the same X-header do not create additional named properties.

MORE INFORMATION

An X-header is a unofficial header field that exists in the message header. X-headers are not specifically mentioned in RFC 2822. However, an undefined header field that starts with "X-" is an accepted way to add unofficial header fields to a message. Messaging applications, such as anti-spam, antivirus, and messaging server applications, may add their own X-headers to a message. X-header fields are usually preserved but ignored by messaging servers and clients that do not use them.
