Aging Keep Time interval for database is non-default

[This topic is intended to address a specific issue called out by the Exchange Server Analyzer Tool. You should apply it only to systems that have had the Exchange Server Analyzer Tool run against them and are experiencing that specific issue. The Exchange Server Analyzer Tool, available as a free download, remotely collects configuration data from each server in the topology and automatically analyzes the data. The resulting report details important configuration issues, potential problems, and nondefault product settings. By following these recommendations, you can achieve better performance, scalability, reliability, and uptime. For more information about the tool or to download the latest versions, see "Microsoft Exchange Analyzers" at http://go.microsoft.com/fwlink/?linkid=34707.]

The Microsoft® Exchange Server Analyzer Tool queries the Active Directory® directory service to determine whether the msExchAgingKeepTime attribute has been set. This attribute represents the time value used to determine when to remove indexes, views, and categorizations. If the Exchange Server Analyzer finds that this attribute is set, a non-default configuration message is displayed.

Indexes used for views that are created in Exchange database tables by an Exchange client that have not been used for a specific time are cleaned up at this time. The msExchAgingKeepTime attribute specifies the minimum index age before it is deleted. The default value in the original release version of Exchange 2000 Server was eight days. In Service Pack 1 (SP1) for Exchange 2000 Server, and in all subsequent versions of Exchange Server, including Exchange Server 2003 and Exchange Server 2007, the default value is 40 days.

CautionCaution:
If you incorrectly modify the attributes of Active Directory objects when you use Active Directory Service Interfaces (ADSI) Edit, the LDP (ldp.exe) tool, or another Lightweight Directory Access Protocol (LDAP) version 3 client, you may cause serious problems. These problems may require that you reinstall Microsoft Windows Server™ 2003, Exchange Server 2003 or Exchange Server 2007, or both. Modify Active Directory object attributes at your own risk.
To view or modify the Aging Keep Time value
  1. Start ADSI Edit.

  2. Double-click the Configuration container, expand CN=Services, expand CN=Microsoft Exchange, and then expand CN=<ExchangeOrganizationName>.

  3. Expand CN=Administrative Groups, expand CN=<AdministrativeGroupName>, and then expand CN=Servers.

  4. Expand CN=<ServerName>, expand CN=InformationStore, and then select CN=<StorageGroupName>.

  5. In the details pane, right-click CN=<MailboxStoreName>, and then click Properties.

  6. In the Attribute Editor, click the msExchAgingKeepTime attribute, and then click Edit.

  7. In the Edit Attribute box, click Clear to clear the value.

  8. Click Apply, and then click OK.

  9. Close ADSI Edit. If a change is made, restart the Microsoft Exchange Information Store service for the change to take effect.
