Like other databases, Microsoft Exchange Server database (EDB file) may also corrupt at some point of time and does not let you perform typical Exchange Server operations. The corruption can be of two types - Logical and Physical. Logical corruption is pretty common and occurs due to internal fault in the database. When it happens, Microsoft Exchange Server database becomes totally unusable and you encounter serious data loss. MS Exchange Server does not include any utility to detect and fix logical corruption. Thus, you are required to opt for
Exchange Recovery to get your valuable data back.
You may encounter logical corruption of EDB file due to any of the following reasons:...

Are you unable to write data to Microsoft Exchange Server database? Is your EDB (Exchange Server database file) inaccessible? This behavior may occur due to either low disk space on Exchange Server computer or corrupt EDB file. If the database is corrupt, you need to restore it from the most recent backup to prevent data loss situations. However, in case backup is not valid or updated, you need to opt for
Exchange Recovery solutions to retrieve data from the database.
In a practical scenario, the Information Store Service of Exchange Server may fail to start and you encounter the below errors in Application Event Log of Exchange Server, while read/writing data from/to EDB file:
“Event Type: Error

The public folders in Microsoft Exchange are used for sharing access and facilitate in collecting, organizing, and sharing information with other contacts in your organization. These are well structured and stored in databases. Also, you can replicate them between the Exchange servers. However, some times you are not able to mount the public folder store. It could happen because of several reasons such as abrupt shutdown, Exchange transaction log file corruption, hardware problems, etc. You should perform certain methods to resolve the issue. However, if you are not able to address the situation then you should use a third-party Exchange recovery software to perform
Exchange recovery.
Consider a scenario wherein you work on MS Exchange Server 2003 Enterprise Edition. One day, you attempt to mount on the Exchange public folder store but unable to do so. An error message is displayed, that is:

Like all other databases, Microsoft Exchange Server database also comprises of several tables. These tables consist of one of more trees and hold records and columns, which are identified as MAPI properties. At times, typically when the database is corrupt, Exchange Server cannot identify these tables as valid database tables. As a result, when attempt is made to access the database, application event log records an associated entry indicating the cause. However, to solve these problems, the prime solution considered for
Exchange Recovery is to restore the database from backup.
Here, the mentioned problem has been narrowed down with the below error message. You can see this or similar error message logging in application event log with an associated event ID 448:
Information Store (2412) Data inconsistency detected in table Msg of databaseE:\Program Files\exchsrvr\mdbdata\priv4.edb (0,524957). For more information, click search.support.microsoft.com/search/?adv=1...

Microsoft Exchange Server 2007 includes a number of advanced and added features over its predecessor Microsoft Exchange Server 2003. Some of its features include, new clustering options, voice mail integration, 64-bit support for the greater scalability, support for web services, and better search options. However, in some situations, you may not access your Exchange Server Database (EDB) file after installing Exchange Server 2007 and attaching database to it. The database becomes totally inaccessible and you face serious data loss situations. At this point of time, it becomes essential to perform
Exchange Server Recovery using reliable tools.
In a practical scenario, you cannot start the Exchange Server services after installing Microsoft Exchange Server 2007 on the global catalog server. But, other services can be started manually. Furthermore, you may see the below events in the Event Log of Exchange Server:...

Microsoft Exchange Server is a well-known application that is used to create collaborative messaging environment. It is installed on server and can be accessed from client computer using Microsoft Outlook. Exchange Server 2003 and Exchange Server 2000 use MS IIS (Microsoft Internet Information Services) to provide Exchange-related services. All configuration settings of the IIS are stored in IIS metabase. The formation of metabase contains various settings of properties of different nodes. However, in some situations the metabase may get damaged and cause critical EDB (Exchange Database) corruption scenarios. To sort out this problem, you need to opt for
Exchange Server Recovery, in case of unavailability of backup.
Corruption of IIS metabase and Exchange Server database is a very serious concern. It can cause several Exchange Server vulnerabilities and make Exchange-related services unusable. In case of metabase corruption, you may encounter the below error message:...

Faulty hardware is one among the most common causes of Exchange Server database corruption. If your application event log frequently records events that point to database damage issues, your hardware is most likely to be replaced. Such situations however, demand
Exchange Server Recovery tools to correct the issue.
Let's elucidate the related problems by taking a suitable example of following event ID.
Event Type: Error
Event Source: ESE
Event Category: Database Page Cache
Event ID: 476
Date: date
Time: time
User: user_name
Computer: computer_name
Description:
Affected_Component The database page read from the file "file_name" at offset offset for number_bytes bytes failed verification because it contains no page data. The read operation will fail with error error_number. If this condition persists then please restore the database from a previous backup. This problem is likely due to faulty hardware. Please contact your hardware vendor for further assistance diagnosing the problem....

In several Exchange database operations, like (but not limited to) backup process, the operating system is called to read database pages that have to be written on disk. During this operation, the checksum value placed in database page header is compared with that returned by READ operation. The backup operation fails if these values do not match. Such errors indicate corruption in database and need backup availability to restore lost data. But in cases when user finds it unfeasible to restore from backup (because it is corrupted or incomplete), a Microsoft
Exchange Recovery tool can help.
To depict the probable events, let's take a related scenario of an Exchange Server 2003 user. When he runs a backup utility to copy the Exchange database, the operation halts with an error that reads:
“Database was not found and could not be backed up. Please make sure database exists and is mounted.”...

Unmountability of a Private Information Store (priv.edb and priv.stm files) primarily occurs when it is corrupted. One of the main reasons for it corruption is improper upgradation from Microsoft Exchange Server 5.5 to 2000. A major hazard that users encounter after improper upgradation is a series of Event Ids, which make the data saved in the private Information Store become inaccessible. In such situations, an effective way to access Private Information Store data is by using an updated backup. However, there are numerous circumstances in which the user has either not created any backup or his backup gets corrupted. To surmount such situations, you need to use an advanced third-party
Exchange Recovery software that can repair the database.
As a practical instance, you migrate your Exchange Server 5.5 database to Exchange 2000. However, after the migration process is complete and you attempt to access the database, you encounter the below series of Event ids:...

An Exchange Server database is susceptible to different corruption problems, such as dirty database shutdown, antivirus scanning, log file issues, and others. Thus an administrator might require different Microsoft
Exchange Recovery tools to solve such problems and to continue working the e-mailing environment.
Further is a scenario that depicts a similar situation of Exchange Server database corruption. As an Exchange Server administrator, you may observe one or more of the below symptoms:
1.You cannot start and/or Information Store service
2.Exchange clients lose the ability to send or receive e-mails. You cannot solve this issue by restarting the server
3.You restore the database from an offline backup but the database is still inconsistent. On running Isinteg utility (database integrity check), it gives the below error message on screen:
“Error 4294966746: JET_errDatabaseInconsistent”...
