Rule Name

The Microsoft Exchange Transport Log Search service failed to access a log file due to an I/O error.


This Error event indicates that the Microsoft Exchange Transport Log Search service experienced an I/O exception while trying to access the specified directory.

The Microsoft Exchange Transport Log Search service is used by the Get-MessageTrackingLog and Search-MessageTrackingReport cmdlets in the Exchange Management Shell, the Delivery Reports tool in the Exchange Control Panel, and the Tracking Log Explorer tool in the Exchange Management Console to search the message tracking logs on the Hub Transport server, Edge Transport server, or Mailbox server.

The location of the message tracking logs is controlled by the MessageTrackingLogPath parameter on the Set-TransportServer cmdlet or the Set-MailboxServer cmdlet. By default, the message tracking logs are located at C:\Program Files\Microsoft\Exchange Server\V14\TransportRoles\Logs\MessageTracking.

An I/O exception can be caused by any of the following conditions:

  • Problems with the physical hard disk drive structure   This condition could include the hard disk drive itself or the hard disk drive controller.

  • Problems with the logical disk structure   This condition could include file system errors or corruption.

  • Transient software errors   This condition could include intense periods of read and write activity on the hard disk drive.

User Action

To resolve this error, do the following:

  • Verify that the drivers and firmware for the hard disk drives and the hard disk drive controller are up to date.

  • Run the command CHKDSK drive letter: /F /R. This command finds and repairs physical errors and file system errors on the affected hard disk drive.

  • Move the message tracking log directory to another hard disk drive.
