Many times, these problems can be figured out and that leads to problems.

Know the root Causes of Exchange Server Database Corruption

There are mostly two main causes that lead to Exchange Server Mailbox Corruption. The damage in EDB files occurs because of logical and physical corruption.

  1. Physical Corruption: This kind of error is occurred because of Hardware Failure. It is considered the lowest level of data corruption.
  2. Logical Corruption: This kind of problem occurs at various levels. At the database level, it is either because of the invalid index entries, cross object chain linkage because of engine failure in the database. During application level, users face corruption in file header, access control levels.

The Exchange EDB file errors may affect the data. Let’s discuss some common Exchange server issues and errors :

  • Exchange Jet error 1018 
  •  Exchange Jet error 1216
  •  Dirty shutdown State Exchange error
  •  Unable to mount Exchange database (hr=0x80004005, ec=-528)
  • 1056749110 Exchange error
  • Unable to initialize Exchange Information Store service – Error 0x8004010f

Corruption Prevention Method 

To escape the risk of logical corruption in Exchange Server, following precautionary methods are needed to be taken:

Install latest service pack of MS Exchange Server in your system. These packs are capable of repairing the database issues in Exchange Server. Make sure the configuration is not changed due to virus intrusions, malware, and adware’s, etc. The corruption originates in the database engine or information store. Microsoft Exchange has many inbuilt programs to check problems in primary database components.

Manual Method to Fix Exchange Server Database Corruption

Microsoft provides the user with inbuilt utility termed as ESEUTIL that performs Exchange 2007 mailbox repair, Exchange 2010 mailbox repair, Exchange 2013 mailbox repair. The ESEUTIL can be abbreviated as Exchange Server Database Utility. It is basically an executable program that repairs all the errors in the Exchange Mailboxes, public folders, and transport server queue databases.

The software is executed via the number of switches that performs a number of functions. The main case of the corruption of the files lies between the ESEUTIL repair mode i.e., ESEUTIL/p. This mode auto corrects the corrupted or damaged database at page or table level, not in application level. The main syntax of the ESEUTIL command while in Repair mode is:

ESEUTIL/P databasefilename.edb

After the repair process is successfully complete, it is preferred to check the integrity of the database by integrity check tool and it also ensures that the process is consistent. For this, make use of ISInteg built-in software.


After completion of the process started by the tool, users need to save the files to a PST folder using the ExMerge Utility. It saves all the data files from newly created PST in the database.

Scenarios Where Built-In Repair Process is of No Use

Though the ESEUTIL is a freeware, it can be used to fix many minor issues in a corrupted database. But, the main disadvantage of the tool is that it is not that much effective. There are many situations in which the repair processes fails and leads to data loss.
