Microsoft Exchange Server stores your data in a database called EDB (Exchange Database) file. Exchange Server contains two main databases, known as Priv1.edb and Pub1.edb. EDB file contains multiple mailbox. A separate mailbox is created for every user, which is accessed using Microsoft Outlook email client. You can create a new user or update existing mailbox by adding the PST file to Exchange Server. In some cases, the EDB file becomes unusable and inaccessible due to corruption. This behavior leads to severe data loss and requires exchange recovery to be resolved.

  • Your Microsoft Exchange Server crashes and the EDB file becomes inaccessible.

  • You have tried a number of methods to restore the database from backup but the backup itself is damaged.

  • When you check the database integrity and consistency using Eseutil.exe utility, it says:
    “File Not Found”

  • You reinstalled Exchange Server from scratch and tried to import the EDB file to a new server but it does not work.


When it occurs, the data becomes totally inaccessible. In order to get your precious data back in such cases, you need to extract the mailboxes from EDB file in .pst file format and then import them to EDB file after creating new mailboxes.
