“Database page read failed verification because of a -1018 error” (page checksum mismatch)
Key reasons and Troubleshooting:

Exchange error code 1018 indicates page inconsistency in an Exchange Mailbox Store. EDB page mismatch error is often resulted due to system hardware failure or malfunctioning. Other possible reasons of EDB page mismatch error are accidental Exchange Server shutdown and virus attacks.

Page mismatch errors of Exchange Server can be fixed by replacing damaged hardware components and restarting Exchange Server. You can also use Eseutil and Isinteg command tools of MS Exchange Server to fix the page inconsistency issue. Use Eseutil/P command followed by Eseutil/d command on the corrupt mailbox store:

  • Eseutil/P [Exchange mailbox Store name]
  • Eseutil/D [Exchange mailbox Store name]

Eseutil/P command will try to recover Exchange mailbox store by omitting bad or invalid pages. It is also known as Exchange Server hard recovery option and should be used in critical EDB corruption. Eseutil/D defragments or trims un-mounted Exchange database. It should be used to delete empty pages and invalid indexes of the Exchange mailbox store.

After successful execution of the Eseutil/P and Eseutil/D commands, you must run Isinteg or Exchange integrity Checker on Exchange Server that has reported error code 1018. The Isinteg command line is:

  • Isinteg -S [Server name] -FIX -TEST ALLTESTS

You must run the Isinteg command repeatedly till Exchange Server shows errors. You can mount the recovered Exchange mailbox store back on the Exchange Server using Exchange management console.

Most of critical EDB issues can be fixed using Eseutil and Isinteg tools. But Exchange Server command tools have some limitations and also sometimes fail to troubleshoot EDB corruption issues.
