The default location of these log files is:

The two log files created for Mailbox Restore are MailboxRestore.log and MailboxRestore.Restore.Server.log.

Performing a physical integrity check on a data store

With Mailbox Restore, you can perform a physical integrity check on the data store and then run procedures to repair any damage. A physical integrity check verifies whether a database can be mounted for recovery and whether it is valid. Performing a physical integrity check reduces the risk of accidentally recovering corrupted data. Mailbox Restore lets you select which aspects of the check to include so that you can target the check on key areas. You can also select all the options for a thorough scan of the database.

Methods for repairing an Exchange database

Mailbox Restore offers two ways of repairing an Exchange database if a physical integrity check discovers corruption.

The Mailbox Restore Physical Integrity Check Wizard includes a repair function that uses basic repair logic for minor repairs and an aggressive repair function that uses advanced logic for heavily corrupted databases.

Also available through Mailbox Restore is the ability to run the Microsoft Eseutil.exe command line utility. In addition to the -/k option for database verifications, Eseutil.exe offers a -/p option for .edb file repairs.

Both the Physical Integrity Check Wizard and the Eseutil.exe utility are effective at addressing database corruption. The option to run Eseutil.exe is available through the Database Maintenance menu for easy access and through the Physical Integrity Check Wizard as a way to confirm integrity check or repair results. You could also run the Eseutil.exe first and then confirm the results with the Physical Integrity Check Wizard.

This option uses a special algorithm to salvage as much data as possible from a corrupted database and does not change any corrupted data that it finds. When the repair is complete, all healthy and corrupted data is accessible.

WARNING: An aggressive repair is intended for heavily corrupted databases only. This type of repair could result in data loss and should not be used for legal discovery. Be sure to have a reliable backup of the database before you select this option.

If you understand the risks associated with this type of repair, in the confirmation box, click I understand, proceed.
