Event ID: 7012 occurs when you search message tracking logs on an Exchange Server 2007-based server

When you search the message tracking logs on a Microsoft Exchange Server 2007-based server, the following message may be logged in the Application log:

Event Type: Warning
Event Source: MSExchangeTransportLogSearch
Event Category: General
Event ID: 7012
Description:
The following message tracking log file is corrupted: '<log file name>'. The corrupted record won't be included in the search results.

This issue occurs because the response from the remote SMTP server may include bare �CR� or bare �LF� characters. Exchange Server 2007 cannot appropriately handle these characters.

To resolve this problem, install Update Rollup 5 for Exchange Server 2007 Service Pack 1.

For more information about Update Rollup 5 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic: For more information about how to obtain the latest Exchange service pack or update rollup, see the following Exchange Help topic:
