Content Indexing has been enabled on this Public Folder database

[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.

The Microsoft® Exchange Best Practices Analyzer Tool queries the Active Directory® directory service to determine if the Content Indexing Rebuild Schedule (msExchCIRebuildSchedule) attribute and the Content Indexing Rebuild Style (msExchCIRebuildStyle) attribute are present and set to anything other than 0. These are attributes of each public information store database.

If the Analyzer tool finds that both of these attributes are present and set to anything other than 0, a non-default configuration message is displayed.

When these two attributes are both set to 1, it indicates that full-text indexing has been enabled for the information store database. Full-text indexing enables powerful and fast searches by indexing every word in a specified database. When you deploy full-text indexing, you select an individual public folder or mailbox store to be indexed. Users can then conduct full-text searches on the messages and attachments contained in the public folder or mailbox store.

By default, the index contains the subject and body of a message, along with names of the sender and recipient and any names that appear in the Cc and Bcc fields. The index also includes text from the following types of attachments: .doc, .xls, .ppt, .html, .htm, .asp, .txt, and .eml (embedded Multipurpose Internet Mail Extensions (MIME) messages) files. Binary attachments, such as pictures and sounds, are not indexed.

Search results are only as accurate as the last time the index was updated. As the content of public folders or mailbox stores changes, the index must be updated to reflect the new content. Index updates can be performed manually or automatically on a schedule.

There are four major categories of full-text indexing files. You can optimize the performance of full-text indexing by arranging the disk location of these files as follows:

  • Catalogs   Catalogs are the main indexes. There can be one catalog for each Exchange store. Place your catalog on a RAID-0+1 array. You can specify the catalog location in Exchange System Manager when you create the catalog.

  • Property store   This is the database containing various properties of items indexed in the catalog. There is only one property store per server. Place the full-text property store on the RAID array. By default, the files are installed on the same drive as Exchange Server.

  • Temporary files   These files contain temporary information used by the Microsoft Search service. Place the full-text index temporary directory on the RAID array. By default, these files are installed on the system drive, which typically does not have the I/O throughput of the RAID array.

  • Gatherer logs   These files contain log information for the indexing service. One set of logs exists for each catalog. The gatherer logs can remain in their default location, or you can move them if you choose.

To enable or disable full-text indexing

  1. Open Exchange System Manager.

  2. Expand Servers, expand an Exchange server, and then expand the storage group that contains the public folder database that you are working with.

  3. Right-click the public folder database, and then click Properties.

  4. Click the Full-Text Indexing tab.

  5. Modify the Update interval field as desired.

  6. Click OK to save the changes and exit the public folder store Properties.
