Disk input/output (I/O) error.

This event indicates a generic error. The Extensible Storage Engine (ESE) was called by the Microsoft® Exchange Information Store service and received an error from the operating system when the ESE tried to read or write to a file. The file could be a database file, a transaction log file, or a checkpoint file. This event will cause the affected databases to dismount. Users who have mailboxes on the dismounted databases will be unable to send or receive e-mail.

To resolve this issue, follow one or more of these steps:

  • Look for related ESE events in the Application log. The related ESE events will give you the specific file name and the specific operating system error.

  • If the issue persists, contact Microsoft Customer Support. For information about how to contact support, visit Microsoft Help and Support.

To search the Microsoft Knowledge Base articles based on criteria that generated this alert, visit the Search the Support Knowledge Base (KB) Web site.
