Microsoft Exchange Server, a messaging tool, is one of the most reliable and highly used applications. To increase usability and high availability of its services, Microsoft time to time adds different advance features to this efficient application. However, sometimes this application starts behaving abruptly and denies accessing its database items. One of most prominent reasons of this abrupt behavior is corruption in Database files. An information store database may get corrupt or damaged due to various reasons, such as software/hardware malfunction, virus attack, human errors, and improper shutdown, etc. As a result, you lose control to all the important data stored in the Exchange database (.edb) file. To overcome this situation, you need to go for an Exchange repair utility.

Let us exemplify the above issue with a real time scenario. While working with MS Exchange 2010 Server, you get the following event in error log:

Event ID:        482

Source:            ESE

Version:           6.5.0000.0

Message:         %1 (%2) %3An attempt to write to the file “%4” at offset %5 for %6 bytes failed after %10 seconds with system error %8: “%9”. The write operation will fail with error -1022

After encountering the above error, all data becomes totally out of reach to you and your users in your organization.

Causes:

 Error -1022 indicates the Disk (I/O) problem which stops Exchange Server from reading a requested page in the database file. The most common cause of this erroneous situation is an information store database file that was severely corrupted or damaged. This error clearly indicates that either file is completely damaged or some parts of it are missing due to which Exchange server is unable to read it.

Resolutions:

To fix this error, you require analyzing the database file system. For verifying and repairing the corrupt database, try any of the following methods:

1) Check for the available online backup and restore it if you have. Ensure that the backup file should be healthy otherwise it may create problem elsewhere.

2) This error shows extensive damage in database so you can also repair it if you don’t have valid backup. For repairing and troubleshooting such kind of performance issues, Microsoft offers some built in utilities. These command line applications will help you to perform repair and make the database error free. But, due to some drawbacks or limitations of these inbuilt tools, you may face critical data loss situations. So, it is highly recommended to make a copy of the database file at a separate place before running these utilities.

3) Use a commercial Exchange server repair program. There is a bunch of Exchange database repair applications available in the market which repairs severely corrupt or damaged databases in an effective and easy way.

These three methods will help you to fix the corruption and recover lost items. Database corruption in Exchange server is a very serious and unwanted issue. It directly attacks on your emails and other communication data. Sometimes this issue makes data unusable for further use. So, taking regular backup of your database file is highly recommended and in case of unavailability of valid backup, uses an advance application to recover all your lost data.
