Most Outlook users have Exchange accounts, and when Outlook connects to the Exchange server, all the mailbox items are synchronized with it automatically. Any organization that uses MS Exchange Server typically stores hundreds of mailboxes on it. Thus, in the event of technical faults with the server, a lot of time and effort is invested into problem finding and rectifying. But often, even after putting a lot of effort hours into it, some problems cannot be fixed since they are just too complex.
It is in such scenarios that a third-party Exchange database repair tools come into the picture to quickly fix complicated issues and bring the server back on track. We’ll be discussing one such reliable tool that will help you fulfill Exchange mailbox repair request with ease and proficiency. Before we look at the solution, let’s understand the root causes:
Reasons behind Exchange Corruption
When we use the term ‘Exchange Corruption’, it means EDB file corruption. EDB file is the Exchange Database file which is the storehouse of all data that resides on the Exchange server. Damage or corruption in this file leads to corruption of the Exchange server.
Some common causes behind EDB file corruption include:
Database Errors that lead to Corruption
More often than not, the server displays some symptoms that eventually lead up to corruption. These symptoms are displayed in the form of errors that unexpectedly crop up while trying to perform various operations on the database. Here’s a list of some common Exchange error codes that lead up to corruption:
One of the log files is missing or doesn’t match the other logs in the sequence.
Page-level corruption in the EDB file.
Assessment of header information in log files and databases shows some important files have been removed. Find here more about Jet Engine Errors
The internal structure of STM file has been damaged while trying to repair it.
Premature exit of Eseutil /p while rebuilding B-trees directly
Exchange mailbox failed to mount since Information Store Service was stopped or is damaged
Information store service was abruptly shut down causing corruption in EDB and STM files.
Exchange Mailbox Repair using ESEUTIL
Microsoft offers an Exchange mailbox repair tool called ESEUTIL to perform Exchange 2013 mailbox repair, Exchange 2010 mailbox repair as well as Exchange 2007 mailbox repair.
ESEUTIL stands for Exchange Server Database Utility, and it is an executable application that finds and repairs errors in Exchange mailbox, public folder, or transport server queue database. The utility can be executed with a number of switches, each performing different functions. The current case of fixing database corruption lies within the scope of ESEUTIL repair mode (ESEUTIL /p). This mode corrects corrupted or damaged databases at the page and table levels, but not at the application level. The syntax of ESEUTIL command in repair mode is:
ESEUTIL /P databasefilename.edb
Once the repair process completes successfully, it is advisable to run an integrity check on the database to ensure that it is consistent. For this, a tool called ‘ISInteg’ is used as follows:
Once this tool finishes working, you should save all data into PST files using ExMerge, create a blank database and again use ExMerge to save all data from PSTs into the newly created database.
Situations Where the Repair Process Fails
Although the ESEUTIL command-line utility is a free way to fix minor issues within the corrupt database, yet it isn’t a very powerful utility. There are a number of cases in which it fails to complete the repair process or results in data loss. Consider the following scenario for instance:
The repair process initiated by executing the ESEUTIL command with the /p switch attempts to repair and validate all system tables and indexes. But, any table, index, or other data that cannot be repaired is discarded. In such a case, the repair process exits with ESE Event ID 500 which indicates that one or more bad pages of data were lost during the repair process. The event also suggests the user run an application-level integrity check on the database since the database might be left in an inconsistent state.
Limitations of ESEUTIL
As is clear from the above scenario, there are situations in which ESEUTIL tool fails to work. Additionally, there are other drawbacks associated with the utility too:
