MS Exchange Repair Tool to repair corrupted or damaged edb file

Are you unable to mount EDB (Exchange Database) database file on the MS Exchange Server 2007 system that is being used in your organization? If yes, then there is a very prominent possibility that the EDB file is corrupt thereby disabling you from mounting it. In such cases, you should try to find out the exact cause of corruption and try to eradicate that issue. In case, nothing is succeeding then you should use a professional Exchange repair software to recover the trapped data.

Consider a similar situation in which you are unable to mount the database on MS Exchange Server 2007. The following error message is displayed:

“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”

In addition, when you check the error log the following event is logged:

“Event Type: Error
Event Source: ESE
Event Category: General
Event ID: 486
Description: Information Store (3932) First Storage Group: An attempt to move the file “E:\Program Files\Exchsrvr\mdbdata\E00.log” to “E:\Program Files\Exchsrvr\mdbdata\E000080A.log” failed with system error 2 (0×00000002): “The system cannot find the file specified.” The move file operation will fail with error -1811 (0xfffff8ed).”

Cause:

You may have run the eseutil /p command on the damaged databases. This problem has occurred because the transaction log files were not removed during the process.

Resolution:

First of all, you should check whether eseutil was run on this system at all or not by performing the following steps:
1.Click Start | Run.
2.Enter ‘CMD’ in the ‘Run’ box and press ‘Enter’ key. The Command Prompt window will be displayed.
3.Enter the following command:
4.c:\program files\exchsrvr\bin\eseutil /mh “c:\program files\exchsrvr\mdbdata\name of Exchange database.edb”
5.Check the repair count field. If it is 0, then the eseutil /p command was not run. For a non-zero count, eseutil /p command was run on the database.
Now, you can transfer the transaction log files to another folder if the database is in a clean shutdown state. To check this condition, you should perform the following steps:
1.Click Start | Run and enter ‘cmd’ in the ‘Open’ box and click OK.
2.To check the private information store, enter the following command in the Command Prompt:
3.c:\program files\exchsrvr\bin>eseutil /mh “drive:\program files\exchsrvr\mdbdata\priv1.edb”
4.To check the public information store, enter the following command in the Command Prompt:
5.c:\program files\exchsrvr\bin>eseutil /mh “drive:\program files\exchsrvr\mdbdata\pub1.edb”
6.Analyze the consistency check results. If the database is consistent, then all the transaction log files are moved to the information store.
7.Transfer all the log files from the directories to a backup folder.
8.Now try to mount the database. It should run fine now.

In the event of still unable to mount the database, the only way of resolving this problem is to use a third-party MS Exchange repair software. These tools are highly interactive in nature that do not damage the EDB files while scanning them.

The best Exchange repair software among all the available tools is Stellar Phoenix Exchange Server Recovery that repairs corrupted EDB files integrated in MS Exchange Server 5.5, 2000, 2003, and 2007. Compatible with Windows 7, Vista, Server 2003, XP, and 2000, this Exchange Server repair tool is able to extract individual user mailbox in the form of separated PST files.

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.

When this problem occurs, the database becomes inaccessible and you need MS Exchange repair to access your precious data.

Cause

You may encounter this problem due to any of the below reasons:

* The backup is not valid or Last Backup Set check box wasn’t selected while restoring the backup.

* The Exchange Server database or Information Store is damaged.

Solution

Try using the below methods to work around this behavior:

* Run hard recovery on the database using “eseutil /cc [backup file path]”

* Repair and restore the database using third-party Exchange repair software.

The applications offer easy and secure recovery with interactive user interface and read-only conduct. Such Exchange repair tools use high-end EDB scanning algorithms to ensure absolute recovery.
Stellar Phoenix Mailbox Exchange Recovery is the most efficient utility used to ensure absolute recovery of damaged EDB files. The Exchange Repair Tool works well with Microsoft Exchange Server 2007, 2003, 2000, and 5.5. It restores emails, contacts, notes, tasks, journals, attachments, and all other EDB file objects.

Are you having MS Exchange Server 2007 in your organization that is giving problems lately? Are you facing problems while mounting the public folder database? It could be possible because of not having sufficient privileges to mount the database. In such cases, you should check the specific options to obtain appropriate user rights. If the issue is not resolved that means the EDB (Exchange Database) file is corrupted, which is disabling you to mount it. In such cases, you should use a third-party MS Exchange repair software to perform Exchange Server repair.

Consider a scenario wherein you are using MS Exchange Server 2007. In this, you are trying to mount the public folder database but you are unable to do so. An error message is displayed in this regard, which is:

“Failed to mount database ‘Mailbox Database’

Mailbox Database
Error:

Also, when you try to log on to the system it freezes at the ‘Applying computer settings’ screen.

Cause:

There could be the following causes for this erroneous situation:

1.The DomainName\Exchange Servers group does not have the Manage auditing and security log user rights.
2.The EDB database file is corrupted.

Resolution:

To resolve this situation, you can perform either of the following methods:
1. Run Setup /PrepareAD: You should run the Setup /PrepareAD command using the Exchange Server CD to restore the Exchange Server configuration in the Active Directory.
2. Add the Exchange Servers group to the “Manage auditing and security log” policy: You should add the Exchange Servers group to the aforementioned policy. After this, you should restart the Microsoft Exchange Information Store service. The problem would be solved now.

However, if you still are facing the similar errors while mounting the public folder database then you should use a third-party Exchange repair software to repair the EDB database. Such Exchange repair tools are extremely safe to use that do not overwrite the existing EDB files while scanning it.

Stellar Phoenix Mailbox Exchange Recovery is an Exchange Server recovery software that is able to repair corrupted EDB files created in MS Exchange Server 5.5, 2000, 2003, and 2007. It repairs the EDB files and extracts the data in distinct PST files. This MS Exchange repair utility is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

MS Exchange Server is one of the two sides of the client-server application. It is extensively used in numerous organizations to successfully carry out corporate communications. Also, it is now accessible in both mobile- and Web-based browsers. The information of the each of the user is stored in an EDB (Exchange Database) file. In due course of time, the EDB file can get corrupt due to various reasons such as abrupt system shutdown, file system corruption, database header corruption, etc. In such cases, you should try to repair the Exchange Server. 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.

However, if the problem is still not resolved then you should use a third-party Exchange Server repair software to do the needful for you. Such Exchange repair tools are read-only in nature that possess fast yet sophisticated scanning algorithms to extract the EDB files in the form of distinct PST files.

Stellar Phoenix Mailbox Exchange Recovery is an MS Exchange repair software that is able to repair corrupted EDB files from all instances of logical corruption. It is specially designed to perform Exchange repair on MS Exchange Server 5.5, 2000, 2003, and 2007. This Exchange repair software is able to extract the EDB file into separate PST files for each user. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

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.

Such tools repair corrupt .edb files safely and employ improved scanning algorithms to recover inaccessible data in a hassle-free manner. Being-read only they do not modify the original content. Therefore, you can use them blindly and isolate the information store corruption issues efficiently.

Stellar Phoenix Mailbox Exchange Recovery is a powerful and reliable application which repairs corrupt .edb files and restores the mailboxes as individual PSTs. Compatible with Exchange Server 5.5, 2000, 2003, and 2007, this Exchange repair software recovers all e-mail messages, notes, journals, tasks, contacts and other components.

When a Microsoft Exchange Server database is corrupt, it is directly reflected when you try to use or start Information Store service. Thus, if you are unable to start the service, one of the possible reasons can be database corruption. The further scenario illustrates one of such problems and then the possible MS Exchange Repair solutions to correct it.

Consider a case when you try to start Information Store service of Exchange Server and it doesn’t proceed as expected. In addition, you receive the below mentioned error message in system log or on screen:

“The Microsoft Exchange Information Store service terminated with service-specific error 4294966277.”

On examining the issue, when you view the Application Event log, the following entry is observed:

Event ID: 0
Source: ESE97
Type: Error
Category: Logging/Recovery

Description: MSExchangeIS ((451)) -1019

Event ID: 1120
Source: MSExchangeIS
Type Error
Category: General

Description: Error 0xfffffc05 initializing the Microsoft Exchange Server Information Store database.

The above symptoms indicate database corruption and thus when you run Eseutil repair utility, the following message is received:

“-1019 0xFFFFFC05 JET_errPageNotInitialized Repair Only: Read an unused page 4294966277”

Consequently, the corrupted database cannot be repaired.

Explanation

JET_errPageNotInitialized error typically indicates a blank page. But, if it occurs when starting the information store, this shows database page corruption. There can be several pages that cannot be initialized. So, Eseutil cannot repair this database.

User Action

Before troubleshooting the issue, you should determine the cause of the error. Generally, these problems are persistent and occur because of failing hardware. Implement the following actions to solve the problem:

Disable all anti-virus applications, file backup programs, and low-level access utilities
Run hardware diagnostics and check system log for hardware-related issues
Restore the database from your previous backup

At times, database backup is not available or exist in invalid state. In such situations, you should use an Exchange Repair Software. Designed to run powerful, yet safe, scanning algorithms, these utilities are competent to restore Exchange database contents, irrespective of the nature of corruption. Also, MS Exchange Repair utilities are easily operable because of their user-friendly design.

Stellar Phoenix Mailbox Exchange Recovery is a comprehensive exchange repair utility designed to retrieve Exchange database mailboxes as individual *.pst files. Supporting MS Exchange Server 2007, 2003, 2000, and 5.5, this Exchange Server Repair tool facilitates you to restore only the required mailboxes. In addition, it can also recover deleted mailboxes.

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 Exchange Repair application.

To elaborate the above situation, consider a real-time scenario wherein you have a MS Exchange database of around 300 GB. The database (priv.edb file) gets corrupted and you also fail to roll back. To resolve file corruption, you run ‘eseutil/p’ utility. The repair process was successfully repairing the file, until it stopped and displayed the below error message:

“Assertion Failed: dPercentage >=0, file G:\ese97\src\eseutil\edbutil.cxx, line 563.”

After the above error message flashes on the screen, the repair process stops, resulting in complete inaccessibility of MS Exchange database. Additionally, the same error message appears every time you use ‘eseutil/p’ utility to repair the database.

Cause:

The root cause for ‘eseutil/p’ utility failure is severe corruption in priv.edb file.

Resolution:

To get past the above error message and to overcome ‘eseutil/p’ utility failure, you will need to follow the below mentioned steps:

1. Use a complete and valid backup to perform restoration of the database.

2. However, in situations where no backup exists or backup falls short in restoring required data, you will need to use a commercial Exchange Server Repair application. Such Exchange Server Repair tools use safe mechanism for repairing the database to maximum possible level. These tools can be used by any computer user, irrespective of its understanding about database repair.

Exchange Repair Software safely repairs MS Exchange database files (priv.edb and pub.edb) after every logical corruption scenario. The read-only MS Exchange Repair tool makes the original database intact. Supported by MS Exchange Server 5.5, 2000, 2003, and 2007, the tool is designed for Windows 7, Vista, XP, 2003, and 2000.

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 Exchange Repair application.

To illustrate the above scenario in detail, consider the below error message that appears when you try to access the records saved in the Information Store:

“Could not start Microsoft Information Service on local
computer, Error 1053: The service did not respond to the start or control
request in a timely fashion”

After the above error message pops up on the screen, the data saved in the Information Store becomes inaccessible.

Cause:

The above error message flashes only when the Information Store gets corrupted due to unexpected system shutdown, header damage, anti-virus scan, log file corruption, or virus attack.

Resolution:

To get past the above error message and to access the records saved in the Information Store, follow the below guidelines:

1. Repair the corrupted .edb file using an ‘eseutil/p’ inbuilt repair command.
2. If the command fails to repair, then restore the file from an updated backup.
3. If backup file is unavailable or corrupted, then use a third-party Exchange Server Repair application to repair the file. Such Exchange Repair applications use effective repair mechanisms to repair any logically damaged MS Exchange database.

MS Exchange Repair software is a comprehensive solution to repair .edb files created in MS Exchange Server 5.5, 2000, 2003, and 2007. The read-only Exchange Server Repair software keeps the original file intact. Compatible with Windows 7, Vista, XP, 2003, and 2000, the user-friendly application is easy-to-operate, and doesn’t require any prior technical knowledge to operate.

The main repository of mailbox data in Exchange Server is the .edb file that is primarily composed of b-trees. Since a b-tree is allowed to have a considerable depth, b-trees deploy indexes to permit quick data access. In Exchange EDB, there are few ancillary trees that hold table indexes to work with the main tree. If these indexes go corrupted, the entire table and sometimes, the whole database become unusable. This is what we refer as logical database corruption. In critical situations, when this type of corruption is not limited to index page corruption, you need to implement Exchange Server Repair solutions.

To understand such potential problems with Exchange database further, consider the discussed scenario and error. When using Exchange Server 2007, you can encounter event 467 logging in the application log. Additionally, on viewing the description section of the same event, you receive an error that reads similar to below:

Information Store (number) Index [index name] of table [table name] is corrupted.

This error typically indicates a corrupted index in the Exchange store. As symptoms, you might observe access violations and repeated crashes. Also, this type of corruption might go undetected for long without any symptoms. Even the Exchange-aware backup may fail to detect this corruption. Event 467 suggests logical corruption at Database (JET database engine) level and is exhibited when JET engine touches this location in the database while reporting it as event 447. For specific root causes, one needs to view the application and system log cautiously as these errors can damage your data badly.

Solution

Following suggestions can help you isolate the depicted problem:

1. If corruption is limited to index leaf pages and not with the database pages, running Eseutil /d (offline defragmentation) alone can perform Exchange Server Repair.

2. In critical problems, you may need to use ExMerge utility to move the mailboxes to a new, blank Information Store.

3. The Exchange Server might be affected from page or database level corruption together with index page corruption. In such cases, you can execute Eseutil /p and then Isinteg -fix commands as Eseutil /d command may not work. You can further use ExMerge tool to put the database again in use.

4. To avoid data loss problems due to Eseutil /p utility, it is however, recommended to opt for a safe third-party Exchange Repair utility.

The Exchange Repair is a professional utility that repairs corrupted Exchange EDB file and restores the mailboxes in separate *.pst files. The Exchange Server Repair product is easy to use with its self-explanatory interface. Designed for Exchange Server 5.5, 2000, 2003, and 2007, the tool is also competent to recover deleted mailboxes.

Exchange Server mailbox store is composed of user mailboxes and system mailboxes. Each mailbox store is made of two files : Priv.edb and Priv.stm. When a disaster occurs to any mailbox store, the EDB file is considered to be the most vital component of recovery, for the reason that it contains all email messages, headers and text attachments of users’ email messages. There are various Exchange Server Repair software available that can repair a corrupted Exchange database, in case when you don’t have any valid database backup to restore.

For instance, consider a scenario when you try to mount your Exchange Server mailbox store. The mount operation might fail logging the events 9175 and 455 in application event log.

Cause

There can several possible reasons that can cause the described issue:

1. An antivirus software is running that has deleted the Exchange log files

2. You have performed soft recovery for database using eseutil /r with incorrect logfile base name

3. Mailbox store is corrupted

Solution

To solve this issue, you need to try these fixes:

1. You should ensure that antivirus software doesn’t scan Exchange Server directories. It can even corrupt the database files. If the log files have been deleted, you should restore the database from backup and play through the log files. In case when no good backup is available, you need to run Exchange repair utilities for bringing the database to consistent state.

2. You need to perform soft recovery using correct log file base name, such as e00, e01, e02 or e03 .

3. If the entire mailbox store is corrupted, you should run Eseutil /r to repair it or restore from backup. However, you can also run Eseutil /p as hard recovery operation, but this causes the dirty pages to delete. So, it is recommended to use commercial Exchange Server Repair tools that can safely repair a corrupted Exchange database.

Exchange Repair software are powerful tools that use exclusive repair algorithms, while providing graphically rich user interface.

Stellar Phoenix Mailbox Exchange Recovery is a fully-featured and non-destructive tool to perform systematic repair of damaged Exchange databases created with Exchange Server 5.5, 2000 and 2003. It is a complete Exchange Repair tool that extracts all user mailboxes by converting them into individual Outlook usable .pst files. The tool can recover all email messages, notes, journals, tasks and other objects.

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 Exchange Repair solution.

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:

“Error configuring message service (MSPST MS) (MAPI_E_EXTENDED_ERROR) (CmapiSession::CreateEMSPSTProfile).

Error opening message store (MSEMS). Verify that the Microsoft Exchange Information Store service is running and that you have the correct permissions to log on. (0×8004011d).”

You cannot open the related .pst files.

Cause

The Exchange database is corrupted due to incomplete or improper merge operation. This can also occur due to insufficient .pst file permissions.

The database corruption can also result because of unexpected shutdown and virus issues.

Solution

You should make sure that you use the latest version of Exmerge utility and the .pst files are not marked as read-only. For removing the read-only attribute from .pst file, you need to click its Properties and clear the associated check box.

To restore the lost data for damaged database, you need to use your last backup. If this is absent or seems to be invalid, you need a third-party mailbox extraction tool. Termed as Exchange Repair software, these tools can repair and rebuild a corrupted Exchange database well while maintaining its integrity.

The Exchange Repair Software is highly competent to extract database mailboxes by using powerful scanning algorithms. Also, these tools are easy-to-use products with a graphically rich user interface.
