Consider a scenario wherein you have Microsoft Exchange Server 2007 running in your organization. When you try to mount the database that is running on the Server, you are unable to do so. An error message is displayed, that is:

“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”

Cause:
There could be the following causes for the aforementioned error message:
1. The eseutil /p command was executed on corrupted databases and the log files were not removed during the process.
2. The eseutil command was executed for an incorrect logfile base as shown in the following example:
eseutil /r three-character logfile base name

Resolution:
To resolve this problematic situation, you should perform the following methods for each of the mentioned cause:
1. Resolution for Cause 1: To do this, you should ensure two things:

A) Whether the eseutil /p command was run: This can be done by using the following command in the Command Prompt:
“c:\program files\exchsrvr\bin\eseutil /mh “c:\program files\exchsrvr\mdbdata\name of Exchange database.edb”
i.If the repair count is 1, then this command was run on this database.
B) If the database is in a clean and consistent state: To do this, you should perform the consistency check on the databases. If the database is consistent, then you should move the log files to a backup folder and then mount the databases.

2. Resolution for Cause 2: You should provide the correct parameter to run the eseutil command. For example,
“eseutil /r e00”

Once you perform the mentioned methods, try to mount the database. You will that the problem is now rectified. However, if it is not so then you should use a third-party Exchange Database Repair to extract the corrupted EDB files. Such .EDB repair tools are read-only in nature and are able to convert the EDB files to independent PST files using fast yet sophisticated scanning algorithms.

Stellar Phoenix Exchange Server Recovery is a software that performs Exchange Recovery of corrupted EDB files. It is able to perform repair edb by converting the Exchange mailboxes into equivalent PSTs for each user. This EDB Repair Tool is designed to repair & recover the mailboxes created in MS Exchange Server 5.5, 2000, 2003, and 20007. It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Consider the below error message that appears when you attempt to mount Microsoft Exchange Server database:

“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”

On viewing the application logs, you view five event ids (9175, 486, 455, 413, and 5) along with their description. After the above error message appears, your database becomes unmountable, rendering to inaccessibility of all its stored data.

Cause:

The above error message appears because of the following reasons:

1. Exchange Server Log file contains an invalid signature.
2. Your anti-virus software erases or quarantines MS Exchange Server Log file.
3. Executing eseutil/p on damaged Exchange databases without deleting the log files.
4. Running “eseutil /r three-character logfile base name” command with wrong log file base name.
5. Corruption of Exchange Server database.

Resolution:

To resolve the above error message and successfully mount the database, you will need to follow the below steps:

1. Recover Exchange Server Log file from quarantine folder in the anti-virus program.
2. Run eseutil/p to repair corrupted database.
3. In case, the repair utility fails, then restore the database from a valid backup.
4. However, with backup file inaccessible or corrupt, use a third-party EDB Repair Tool.

An .EDB Repair application uses advanced repair techniques to repair logically damaged Exchange Server database. The tool can be used by any technical user who has no prior database repair experience.

EDB Repair Tool is a secure, yet advanced Repair EDB utility that repairs all corrupted databases created in MS Exchange Server 5.5, 2000, 2003, and 2007. The software is user-friendly and easy-to-understand. It can be installed on Windows 7, Vista, XP, 2003, and 2000.

To elaborate the above scenario, consider a real-time case wherein you encounter the below error message while trying to access the database:

“-1018 JET_errReadVerifyFailure”

On viewing the event log, you get the below event ID 515 stating:

“%1 (%2) %3 Database %4: Page %5 failed verification due to a flush-order dependency mismatch. This page should have flushed before page %6, but the latter page has instead flushed first. Recovery/restore will fail with error %7. If this condition persists then please restore the database from a previous backup. This problem is likely due to faulty hardware “losing” one or more flushes on one or both of these pages sometime in the past. Please contact your hardware vendor for further assistance diagnosing the problem. ”

After the above error message flashes on your screen, the database can not be opened. Additionally, the same error message appears every time an Exchange user tries to access the database.

Resolution:

To resolve the above file-level corruption error, you need to:

1. Use an adequate database backup to perform restore
2. Use Eseutil or Isinteg utilities to repair database
3. Use Exchange Server Disaster Recovery Analyzer Tool to mount the database.
4. In case where all the above measures fail to resolve the problem and the database remains inaccessible, you need to search for a third-party .EDB Repair application. Such EDB Repair Tool use powerful scanning methods to repair and restore logically damaged MS Exchange database.

.EDB Repair Software is a secure and reliable application that repairs logical databases created in Exchange Server 5.5, 2000, 2003, and 2007. Supported by Windows 7, Vista, XP, 2003, and 2000, the non destructive Repair EDB utility stores recovered mailboxes in .pst file format.

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 2003, 2003 or 2007.

Cause

Error 0xfffffa84 of event ID 9519 is logged, if database index corruption is when you:

1. Run database repair command- eseutil /p

2. Apply MS Windows service pack and an index cleanup process starts. This also prohibits mounting of the Information store databases and results in events 611 and 609.

Solution

To troubleshoot the given problem:

1. You need to install the hotfix provided by Microsoft to fix index loss problem caused due to eseutil /p utility.

2. If you experience the above issue after installing Windows service backup, the most suitable option is to restore from last available backup. In case, you do not have any valid backup, you need to perform offline defragmentation using eseutil /d command.

3. You can alternatively repair the corrupted Exchange Server database files and convert the mailboxes to usable *.pst file using third-party EDB Repair Software.

EDB Repair software employ powerful set of procedures to extract mailbox data from corrupted Exchange database file. Built with interactive designs, these Exchange Repair software are simple to operate. Also, these software are easily available and can be directly downloaded from their website without any risk.

This EDB Repair Software restore e-mails, notes, calendars, and other items, while also keeping the original database intact. The tool supports MS Exchange Server 2007, 2003, 2000, and 5.5.

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:

-1852 0xFFFFF8C4 JET_errLogCorrupted

Logs could not be interpreted 4294965444

The related event ID is 9513. You can observe the same error when restoring the database from backup.

Cause

Event 9513 in Exchange Server 2007 and the above error suggest that the Information Store Service, which is using ESE, cannot read the transaction log files because they are corrupt. As a result, when you try to mount the database after dirty database shutdown or attempt to restore from backup, ESE fails to replay the log files and also to bring the database to a consistent state.

Solution

Following are few concrete solutions that you can apply to solve the depicted issue:

1. Check the application event log for more ESE events. This can help you to find the specific reasons and solutions to the existing problem.

2. Try to duplicate the behavior- mounting the database or restoring from backup.

3. Try to restore the database while excluding the corrupted log files and its sequence. But this operation will cause data loss

4. Run eseutil /p command. Keep in mind that this is a hard repair command and is likely to delete the corrupted and unreadable pages

5. Use a third-party EDB Repair utility. An EDB Repair Software can analyze the corrupted database and extract the lost data using powerful, yet safe, scanning algorithms.

EDB Repair Tool is an efficient .EDB Repair product that scans corrupted Exchange database and extracts the mailboxes in readable PST files. The software supports Exchange Server 2007, 2003, 2000, and 5.5. With an interactive, user-friendly design, the software is easy to operate. The tool is compatible with Windows 7, Vista, XP, 2003, and 2000.

Microsoft Office 2010

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

Event Source: ESE

Event Category: Logging/Recovery

Event ID: 412

Date: 7/3/2008

Time: 1:40:37 PM

User: N/A

Computer: SMTPBRMDBALEX2

Description:

Information Store (4948) e53f288d-df1b-47ba-9c3b-901e530848a5: Unable to read the header of logfile E:\exchsrvr\mdbdata\E003C9F3.log. Error -530.

The error indicates that it cannot read the logfile header.

Cause

Error -530 occurs specifically due to signature mismatching of log files. The log file signature makes sure that Exchange may replay a correct set of log files. Each database header includes this signature information of the current log file. In case these values fail to match, error -530 occurs indicating the same.

Solution

To solve the existing -530 error issue, you need to implement solutions like:

1. Restore from the last Information Store backup. Rename the corrupted EDB and STM database and create new databases to restore lost data from backup.

2. Open the command prompt and navigate to the Exchange Server directory (usually, C:\Program Files\Exchsrvr\BIN). Next, run Eseutil /P for the corrupted database.

The command causes corrupted pages to delete and creates unused space. Thus, you need to run Eseutil /D command to defragment the database and then run isinteg -fix repeatedly until you receive no errors or get the same errors after two times.

After running the hard repair through Eseutil /P command, the database may not be stable as data loss is likely. Thus, it is recommended to either move the mailboxes to a new database or run a third-party EDB Repair Software instead of performing the hard repair operation. The EDB Repair tools are exclusively built products designed to scan and repair the corrupted Exchange databases.

EDB Repair Tool is a professional utility that repairs the corrupted EDB database and provides selective mailbox recovery option as *.pst files. The EDB Repair Software has an interactive design that makes it easy to operate. The tool supports Exchange Server 5.5, 2000, 2003, and 2007.

For instance, consider a situation when you use Exchange Server 5.5 and upgrade it to Exchange Server 2000. After this, when you try to mount the Private store of Exchange, it fails and gives an error message, similar to below:

“Database “First Storage Group\Private Information Store (NTSRV01)” could not be upgraded to version 3.2. Error 0xfffff9bb.”

This error is associated with event ID 1187 in application event log of Exchange Server.

Cause

The mentioned error indicates that the Setup program has been unable to upgrade the Exchange database in question. It cannot upgrade the database to the specified version. This may occur if:

1. The database in effect is not included in upgrade sequence and is incompatible with the current Microsoft Exchange version.
2. The database is corrupt.

Solution

You should first analyze the error text and try these solutions to recover from this problem:

1. Make sure that the running MS Exchange version is compatible with that of database you are trying to mount. If not, you should try to mount it on a different server installed with required Exchange version.
2. To check if the database is actually corrupted, you should examine the application log for associated events. If it is, restore the database from backup or run eseutil repair utilities. For safe database repair, you are suggested to use third-party Exchange Repair software.
3. Sometimes, the described error may result because of failed upgrade, so you should try to upgrade it again.

As one of the instances, suppose you experience an unexpected power outage with your Exchange Server computer. After this, when you start the database, you get some events (such as event 467, 9297 etc.) logging in the Application log. When you run eseutil commands to check the database integrity, it gives an error as below:

“Operation terminated with error -338 (JET_errBadParentPageLink, Database corrupted)…”

If you execute isinteg command, this may result no errors.

Cause

The error -338 occurs due to corruption in parent database and is returned by directory manager. It can occur because of unexpected power failure.

Solution

You can solve the above issue by applying these measures:

1. Check the last online backup. If available and valid, restore from it.
2. You can create a new mailbox store and move all possible mailboxes to it
3. If the above solutions don’t work, you can use esesuitl /r (soft recovery) and/or eseutil /p (hard recovery) commands to repair the corrupted database. The latter option can cause data loss as it deletes the corrupted pages. So, it is suggested to backup your database before applying it.

In case, none of these resolutions proves valid, you need a third-party Exchange Repair utility. These software offer safe EDB Repair in each case of database corruption and have high competency to maintain the original database integrity. Moreover, these utilities are quite easy to install and use with self-explaining documentation.

Stellar Phoenix Mailbox Exchange Recovery is a reliable and advanced utility that repairs damaged or corrupted Exchange database. The high-end EDB Repair Tool supports Exchange Server 5.5, 2000, and 2003. The software implements powerful scanning mechanism and restores all the mailboxes in individual *.pst files. The tool is compatible with Windows 7, Vista, XP, 2003, and 2000.

For instance, consider a scenario in Exchange Server. You try to mount a mailbox store, but the operation fails with the below error message:

“Exchange is unable to mount the database thay you specified. Specified database: Servername\First Storage Group\Mailbox Database; Error code: mapiExceptionCallFailed: Unabble to mount database. (hr=0×80004005, ec=-528)”

The error occurs each time when you try to mount the store. As a result, all the clients connected to server are disconnected.

Cause

The above error can occur if you remove a (or more) log file, which has not been committed to the database yet.

Solution

To solve this issue, you need to move the transaction log files to a different folder. For this, follow the steps mentioned underneath:

• Stop Information Store and all databases in the storage group

• Verify the integrity of database by running esesutil /mh command, followed by database name (for example, for Mailbox Store1 database, name is Mailbox Store1.edb). Examine the ‘State’ value under its header information

• If the database is in Clean Shutdown (Consistent) state, you can safely remove all the transaction log file and save them to a different folder. Make sure you don’t remove the current transaction log file

• If the database is in Dirty Shutdown (Inconsistent) state, restore from the last online backup. In case backup is invalid, run eseutil /r command for soft recovery. If this fails, you can run eseutil /p command for hard recovery or use an EDB Repair Software. The former option (hard recovery) causes data loss as it deletes the corrupted pages. An EDB Repair utility can safely repair a corrupted Exchange database and provides secure data restoration.
