An error message while opening an Microsoft Exchange Server database primarily occurs when the database gets corrupted or damaged. In most situations, the database corruption occurs due to improper, unexpected, or dirty shutdown. Corruption in Exchange database can be surmounted by using a repair utility known as 'ESEUTIL /P'. This utility checks the logical and physical integrity of the database and performs repair to maximum possible level. However, there are certain situations, where the database remains corrupted when this utility fails to repair. In such situations, the user needs to restore the Exchange database from an adequate and complete backup. But, if in case of no backup availability, you will need to repair the Exchange database (.edb file) by using an effective third-party
Exchange Repair software.
To illustrate the above case, consider a practical scenario where you encounter the below error message that appears after corruption in Exchange 2003 database:...

Information Store in MS Exchange Server database saves all the public folders and mailboxes. These Information Store components further include two files – priv.edb and priv.stm (in Mailbox Store), and pub.edb and pub.stm (in Public Folder). Corruption in either of the four files stops the Information Store service and leads to inaccessibility of all the data stored in the Exchange Server database. Few main causes for file corruption could be improper server shutdown, header corruption, anti-virus scanning, and malicious software like virus. To overcome file damage situations and access the data saved in MS Exchange database, you will need to repair using an inbuilt repair utility named 'eseutil/p'. This utility, although successful in most cases, can fall short when the database is severely damaged. For such situations, the user is not left with any other option, but to search for a powerful

Microsoft Information Store is the core database that consists of both public folders and mailbox store. The store uses a transaction-based technology service to access all its data. To start this services, the user needs to type 'services.msc' in 'Run', and then select 'Microsoft Exchange Information Store' service. While in most cases the service starts after you follow the above procedure, there are certain situations wherein the service fails to start. Such situations primarily occur when the Store gets corrupted or damaged. In most situations of Store corruption, the user receives an error message, that does not allow him/her to access the Store records. To overcome any Store corruption scenario and to access its data, the user needs to opt for a valid backup of the Store. However, the solution of restoring from backup fails if the user has not maintained any backup. In these situations, the user needs to repair the database using a commercial

Eseutil/p is an inbuilt repair utility of MS Exchange Server that repairs corrupted Exchange Server databases at both table and page level. While the repair utility proves successful in repairing most of the corrupted databases, there are certain situations wherein the command fails to repair a corrupt database. In such situations, it displays an error message. This happens when the database is severely damaged. Since the database cannot be repaired, it remains corrupt, and the data saved in it remains inaccessible. To access database in such situations, a user needs to restore database from a previous online backup. However, in the absence of an updated backup, a user needs to repair the database using a
Exchange Repair application.
For detailed explanation of the above problem, consider a practical case wherein your Exchange Server database gets corrupted. And, when you try to repair the database using Eseutil/p utility, you encounter:...

Exchange Server transaction logs are stored on Exchange computer hard drive and are crucial for the working of database (*.edb) file. When you start any Exchange Server, ESE (Extensible Storage Engine) checks the database for consistency. This information is revealed by a specific flag in the database header that shows database status as dirty or clean. The dirty database status indicates that there are some uncommitted transactions that need to be replayed. Exchange tries to replay them at the time of mount, but may fail if cannot read them. The reason can be corruption of log files. Such situations can force you to use an
EDB Repair Software.
To comprehend these potential problems, consider you use Exchange Server 2007. You experience an unexpected crash (Dirty database shutdown). The next time when you try to mount the database, it gives the below error message:

The key construct of an Exchange database file, EDB, is B-trees. Similar to all other B-trees, these structures have hierarchical pages and indexes to allow fast and efficient search. An Exchange Server database show abrupt symptoms, when these indexes get corrupt or are missing. This can occur due to numerous reasons and will make you resort to
EDB Repair steps.
While Exchange database indexes are corrupted or missing, the MS Exchange database troubleshooter tool can encounter several entries with event ID 9519 having error code 0xfffffa84 logging in the application log. Due to this, Exchange Server users might experience problems while accessing or mounting the database.
This problem is observed in MS Exchange Server 2000, 2003 or 2007.

One of the most important objects of Microsoft Exchange that saves all the database files and transaction logs is 'Information Store'. This component, once corrupted, results in inaccessibility of all the data/information saved in database. Few most common reasons for the information store corruption are improper database shutdown, log file damage, and anti-virus scanning. An easy way to access the information store after its corruption is by using a complete backup. However, if the backup is unavailable or corrupted, then you need to search for an effective third-party
Exchange Server Repair software.
As a practical case, you receive the underneath error messages while trying take a backup of your database files, using Veritas software:
“Information Store - is a corrupt file. This file cannot verify.”
On viewing the event log of your Exchange Server, you view the below error message:

Most of the Exchange database problems (including corruption) occur because the administrator continues to use the very old hardware without any refresh. Thus, it is suggested to keep a timely check through application log and related information. Once the EDB database corruption is confirmed, the administrator can either restore from a good backup or select an
EDB Repair option.
To comprehend such situations, let us consider a problem when you cannot mount the Exchange database. You observe that all Exchange services run without any error, but when you try to mount the database, it reports an error as below:
Event Type: Error

Exchange Information Store service is the most critical component, without which the server is of no use. The Information Store is comprised of different storage groups and if these groups go corrupted, it results into data inaccessibility. Further, the Information Store service also stops. In critical situations, when you cannot restore from the backup or repair it using standard utilities, an
Exchange Server Repair tool is required to be used.
For example, when using Exchange Server, you might observe one or more of the following symptoms:
- You attempt to start Information Store service, but cannot do so with the following error:
“Windows could not start the microsoft exchange information store on local computer.”
- When you try to start the Exchange event service, this also fails and the following error occurs:
“Could not start the microsoft exchange event service on local computer...

If an Exchange Server database doesn't undergo proper shutdown, it remains attached to its associated transaction log stream. Exchange identifies this state of database as 'Dirty Shutdown'. This simply means all the data from the transaction log stream has not securely committed to the database files. You can examine the database state using eseutil/ mh command that examines the database header information. At next startup, Exchange detects this problem and applies the required logs to the database. In this situation if you remove the transaction logs, the database loses the ability to mount and cannot be restored unless you apply a backup or use some
Exchange Server Repair utilities to repair it.
As one of the practical problems of such problems, you may find an Exchange database failing to mount. Also, you receive an error that reads similar to below:

Microsoft Exchange Mailbox Merge tool or Exmerge.exe allows you to extract mailboxes' data from an Exchange running computer and then merge it into same mailboxes stored on a different computer running Exchange Server. The tool copies the required data from the root server into .pst files and then merges it in the personal folders into mailboxes stored on the target server. At times, you cannot open the .pst files after using Exmerge.exe to extract the data to another Exchange Server database. This can occur due to incompatibility issues, new format of Outlook for PST, incorrect .pst file privileges or database corruption. As a result, the database becomes corrupt and you need an efficient
Exchange Repair solution for Microsoft Exchange Server.
For example, when you try to run Exmerge.exe to move data from an Exchange Server computer to another, you may receive the below error for various users:...

An Exchange Server database can get corrupt for several reasons, which include unexpected power failure, corrupted log files, network errors, virus infection and others. Consequently, the database may stop and fail to mount. You can try repairing the database using eseuitl utility. If this fails too, it compels you to apply the latest backup available or repair the database by an
EDB Repair product.
For instance, you might come across the below error when dealing with Microsoft Exchange Server:
“Database page read failed verification because of no page data.”
It further suggests to move the existing databases to a new hardware. The error is logged with event 476 in application event log.
Cause
The above error means that the database read operation has failed It generally occurs with error 1019. The causes are:
1.The specific database page that has been referenced within the database file is expected to be in use, but Exchange finds it empty or uninitialized...
