Defragmentation enables you to compact your Exchange Server database to reduce the unused storage space and increase the performance of the server to a significant level. However, the interruption of this process due to various reasons causes some serious damage to the Information Store (IS). When the IS gets corrupt, user mailboxes in the EDB file become inaccessible.

In such scenario,  use Stellar Mailbox Exchange Recovery to easily recover back all your lost mailboxes.

Note: You should keep your STM and EDB files at one place before starting with the recovery process.

Steps to repair and restore the corrupt EDB file using Stellar Repair for Exchange-

  • Download, Install and Launch Stellar Repair for Exchange..
