SYMPTOMS
If you index .msg files by using Indexing Service and query the files by using the contents property, you may not receive any hits in the result.



CAUSE
MSG files are binary files, which are associated with the binary Null IFilter in Indexing Service. The Null IFilter is not able to extract the textual information out of the .msg file. As a result, you do not get any results if you query the contents property.



STATUS
This behavior is by design.



MORE INFORMATION
In Windows NT Server 4.0, .msg files are processed by default with the Default IFilter if the Filter Files with unknown extensions option is configured in Index Server 2.0.

The Default IFilter extracts textual contents out of the .msg files. In this case, you get .msg files in your query results.

For Indexing Service, Microsoft recommends that you write a custom IFilter for .msg files. To do this, refer to the following section in the MSDN Library:

Platform SDK\Base Services\Indexing Service\Using Custom Filters with Indexing Service
