MS Exchange Repair Tool to repair corrupted or damaged edb file

Microsoft Exchange Server provides you with an inbuilt tool, called Exchange System Manager to manage the Exchange Server operations. It is a narrowed MMC console, which is automatically installed during Exchange Server installation. It helps you to mount the Exchange Server database and makes it accessible by the users. However, under some situations, the database can not be mounted using Exchange System Manager and you run across database inaccessibility. This problem is usually caused by corruption of the EDB (Exchange Database) file or Information Store. It leads to data loss and requires Exchange Server repair to be sorted out.

For example, you may run across the below error message after you restore the Exchange Server database from online backup and then try to mount EDB file using the Exchange System Manager tool:

“An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.

ID no: c1041724
Exchange System Manager”

At the same time, you may see the following entries in application event log of Microsoft Exchange Server:

“Event Type: Error
Event Source: ESE98
Event Category: Logging/Recovery
Event ID: 619
Description:
Information Store (nnnn) Attempted to attach database
‘D:\Exchsrvr\MyStorageGroup\MyDatabase.edb’ but it is a database
restored from a backup set on which hard recovery was not started
or did not complete successfully.

If you are not able to perform Exchange repair, then you should use an MS Exchange repair software to do the needful for you.

Consider a scenario wherein you are using MS Exchange Server 2007 Management Pack for Operations Manager, which is used to monitor the MS Windows Application Event logs. While working on the Transport database, you encounter the following error message:

“A Transport database operation has encountered a fatal error. The database may be corrupted. The Microsoft Exchange Transport service is shutting down. Manual database recovery or repair may be required.”

After the above error, Microsoft Server does not let you access your database. At this point, you have to verify the cause of this problem and perform Exchange repair by resolving it.

Cause:
The root cause of this erroneous situation is that the specified database in the error message is damaged, which is causing the MS Exchange database services to mount it.

Resolution:

To resolve this problem, you should perform either of the following methods:

1. Delete the database: You should delete the database in question along with the respective transaction logs. After the deletion, a new copy of the database with the transaction logs will be created automatically. However, you would not get the previous data in this case.

2. Repair the database: You should try to repair the database using the Eseutil /P utility on the corrupted database. After the database repair, restart the MS Exchange Transport service to ascertain whether the error has been resolved or not.

Information store is the most vital component of Microsoft Exchange. When the Exchange Server is hit by corruption issues, information store also gets affected. It is made up of four database files viz Priv1.edb, Priv1.stm, Pub1.edb and Pub1.stm. When corruption occurs either Prive1.edb or Pub1.edb falls prey to it. In event of corruption, an Exchange administrator can observe various symptoms including the MS Exchange Information Store service won’t start, or clients cannot send or retrieve e-mails or abrupt error messages. In order to isolate the issues, the administrator must use the updated backup copy of the database. However, if no backup is available, he should immediately switch to MS Exchange Repair solutions.

Consider a scenario, wherein, you, being the administrator, try to mount the mailbox store in Exchange System Manager, and receive the following error message:

“Unable to Mount the Mailbox Store with error c104173c The Information Store is Busy”

Cause

The above error indicates the possible corruption in one or both edb files (Priv1.edb or Pub1.edb) of information store.

Resolution

In order to troubleshoot the issue, you must perform the following Exchange Repair steps:

1. Run eseutil/mh command in order to determine if the database is consistent
2. If you get the following output ‘Clean Shutdown’ , move out all the log files from Exchsvrmbddata folder
3. But if you get ‘Dirty Shutdown’ as output, perform soft recovery by using eseutil/r
4. If database does not come to a consistent state, perform hard repair by using eseutil/p command.
5. If you use the above command, you may lose some Exchange Server data, including the messages that were contained in the log files that were not committed to the information store database. Therefore, it is a wise decision to use a third-party MS Exchange Repair application.

Backup is the important and easiest prevention step to safeguard your data on Exchange Server. In case of any mishap, you can easily restore your data from recent backup. But in some situations, while backing up your data, you might come across a number of error messages and the backup process fails. This behavior generally occurs due to corruption to the database and it renders all of your critical emails, notes, contacts and other data inaccessible. It results into data loss and require Exchange Repair to be sorted out.

In a practical scenario, when you try to backup Exchange Server 2003 database, the following error occurs:

“WARNING: Portions of cannot be read. The backed up
data is corrupt or incomplete.”

At the same time, a number of Events are logged into Exchange Server Application Event Log that may sound like the following one:
