How to Repair Exchange EDB file – Complete Solution

Note: This is a guest post written by Naomi Johnson

Every organization that uses Microsoft Exchange needs a way to recover emails, calendars, and other data if users lose them. In an on-premises Exchange environment, backing up the databases is strictly for recovery purposes instead of archival storage. These databases are EDB files and can be found in the same folder as the MS Exchange database files.

Exchange Server Data Recovery is not an easy job. Unlike other services, the presence of an Exchange server requires regular monitoring and maintenance to ensure uninterrupted services. Disasters can happen at any time, and you must be able to recover quickly from a failure or mishap.

If you’ve been using Microsoft software for long enough, you probably know this isn’t going to be a quick or simple answer. Let’s see what you need to repair the Exchange EDB file yourself.

What is an EDB file? And how to repair Exchange EDB file?

EDB files are the primary storage locations for Exchange mailboxes and databases. When you take a backup of an Exchange mailbox, it’s usually stored as an EDB file. If something goes wrong with your primary storage location and you need to restore that data, these files come in handy.

EDB files are mainly used to store mailbox metadata, such as their size, creation date, upgrade history, etc. (around 200KB). Because of this lightweight attribute, it is common practice among administrators to store multiple copies of each EDB file across different drives or servers so if one fails; they do not lose access to all documents simultaneously. Usually, when users connect to Exchange server for sending and receiving emails, they can access their e-mail messages directly from their client inbox.

Causes of Microsoft Exchange EDB File Corruption

Exchange Server saves its data in EDB files, and files on Exchange servers are prone to technical errors. See the bullet point below for a possible cause of the EDB file corruption.

  • The Exchange server was shut down.
  • Unexpected power outage
  • Errors on the Exchange server
  • Surprising Exchange server failure
  • Virus Attacks or Malware
  • Third-party software is having difficulty.

A single cause from the list can corrupt EDB files; however, the files can be repaired by following the simple recovery procedure.

Methods for Repairing a Microsoft Exchange EDB File:

Two ways to repair an EDB file are: manually using the inbuilt ESEUTIL and professionally using a tool.

  • Using the Eseutil command, repair the EDB file.
  • Go to Start and click Run.
  • Enter cmd into the Run dialogue box and press OK.
  • Now navigate to C:\Program Files\Exchsrvr\bin
  • Then, in the command prompt, type Eseutil.exe.
  • The Eseutil utility (Eseutil.exe) has two repair modes: “/r” and “p.”
  • This command is now only useful for recovering the MS Exchange database.
  • Users can also use the Eseutil/p command line to recover distant Exchange EDB files such as priv1.edb and pub1.edb if the EDB database files are severely corrupted.
  • Eseutil /p C:\Program files\Exchsvr\mdbdata\ primary name.EDB
  • After users have restored the damaged.edb database files with the Eseutil/p command, run the Eseutil/d command line to defragment the Exchange database.
  • Now, run an Eseutil.exe command to inspect the stability of the repaired EDB database, which will display information such as; sinteg –s {Exchange Server name}-fix-test all tests.
  • Now, select the .edb files recovered from MS Server directory.
  • Now, run this Exeutil.exe command until no errors are displayed on MS Exchange Server.
  • To test the consistency of the fixed Exchange EDB database, use the Eseutil/G command line.
  • Remount the repaired Microsoft  Exchange database files (.edb) using the Exchange Server administration tools.

However, the manual method is complex, and a single incorrect command can tip the scales, resulting in data loss. So, using a professional tool to avoid data loss and repair EDB files (corrupted EDB) of Exchange is highly recommended. This is a more secure and relaxed method of resolving the problem.
