“This mailbox exceeded the maximum number of corrupted items that were specified for this move request”

On getting this message, entire migration process comes to a halt and the data gets inaccessible. In worst situations, the data may get corrupt or deleted. In order to repair corrupt files, one must follow the steps below:

As we know that the Exchange Administrator has the sole right to define the limit of corrupt items in Exchange mailbox so he can increase this corrupt item’s limit as and when desired. If this does not work, user may try the inbuilt ESEUTIL utility provided by Microsoft. ESEUTIL defrags the Exchange Database and checks for integrity. It repairs the EDB file and can be found at “\EXCHSRVR\BIN directory.”

For checking integrity of the database, type

ESEUTIL /G C:\Program files\exchsrvr\mdbdata\priv.edb

To complete the Exchange Server Recovery follow ESEUTIL/P command.

ESEUTIL/Pc: \program files\exchsrvr\mdbdata\priv.edb/Se:\exchsrvr\mdbdata\priv.stm/Te:\tempdb.edb
This command repairs priv.edb database. If in case, you have no STM file, you can create one with ESEUTIL/CREATESTM. You can view the detailed log file also. Just remember to take complete backup of Exchange Server before running ESEUTIL.
However, both the methods require certain technical skills and precision that is not everyone’s forte. Hence, third party Kernel for Exchange Recovery Software comes to the rescue! Kernel for Exchange Server Recovery is easy to use, impeccable software that not only repairs public, private and STM files but also assures you of the accuracy. The software is available for free trial edition as well that enables users to try the utility before purchasing it.

Blog Summary:

When trying to migrate from one Exchange Server to another, you might face several issues. Under worst-case scenario, you might get error in the middle of conversion and process might stop leading to data corruption. Instead of trying complex inbuilt utilities, try third party Kernel for Exchange Server Software that repairs entire Exchange Database effortlessly!

EDB or Primary Exchange Database holds different email folders of one or several Outlook user mailboxes mounted on Exchange Server. When Exchange Server runs slow or disconnected from internet, all EDB files of that server goes in offline mode. Offline EDB files fail to mount on Live Exchange Server if internet connectivity is not restored for long time. Primary Exchange databases may also get damaged due to accidental deletion of Outlook mailbox, virus codes and
corrupt storage media.

You will receive different error messages, when your Exchange Server crashes or EDB files are
Damaged. MS Exchange Server is equipped with two command utilities i.e., Eseutil.exe and Isinteg.exe, that can fixes logical, page sum errors and other errors of EDB files.

For complete restoration of all offline EDB files on Live Exchange Server, you must use both Eseutil and Isinteg commands. Both inbuilt tools of Exchange Server work on offline EDB files and can be used from MS DOS prompt. You must unmount the corrupt EDB file from Exchange Server before using Eseutil commands. You can defragment, repair or restore both Transaction Logs and Primary Exchange databases with Eseutil. The Eseutil command line to defragment EDB files is:

• C:\Program Files\Exchsrvr\Bin> Eseutil /d Filename.EDB > [options]

You can defragment both Public and Private EDB files with Eseutil. The Esutil commands to repair Private and Public Exchange Information Store is:

• C:\Program Files\Exchsrvr\Bin> Eseutil/d/Ispriv Filename.EDB [options]
• C:\Program Files\Exchsrvr\Bin> Eseutil/d/Ispub Filename.EDB [options]

You can also use Eseutil to rebuild corrupt EDB databases:

• C:\Program Files\Exhsrvr\Bin>Eseutil/p filename.EDB [options]

Before mounting the repaired EDB files on Exchange Server, you must also perform database integrity check with Isinteg utility. It helps the system administrator to recover both EDB and Log files from dirty exchange Shutdown situations. The Isinteg command to repair corrupt database folder is:

• C:\Program Files\Exchsrvr\Bin>isinteg -s (SERVER) -fix -test alltests

In certain cases, EDB file recovery is not possible with Isinteg and Eseutil commands. Therefore, you must use a professional tool that supports data recovery from both mounted and offline EDB files.

Tool to Restore Exchange Server quickly repairs unspecified number of EDB files in single cycle. It successfully extracts an Outlook mailbox from a corrupt EDB file and saves in either PST or EDB file. Tool to Restore Exchange Server uses three database recovery modes to repair corrupt mailbox Store or Public Exchange Store. This software quickly fixes severe corruption errors such as Jet Engine Database errors of EDB files. Tool to Restore Exchange Server supports all versions of MS Exchange Server and MS Outlook.

Summary: An Exchange Information Store consists of EDB, Transaction Log and Checkpoint files. A Primary Exchange Database or EDB file stores single Outlook mailbox, linked with Exchange Server. Corrupt EDB files also halt the email communication on an Exchange Server. Exchange Administrator can use inbuilt Eseutil and Isinteg commands to fix most corruption errors of offline EDB files. However Jet Engine errors and other severe corruption issues of EDB files can be fixed only with a proficient tool to repair Exchange Server.

On encountering errors in EDB files all the data items of the mailbox such as emails, contacts, appointments, calendars, folder, drafts, sent items, to-do, tasks, etc lose access. Consider some real situation based instances that are generally encountered in case of Exchange file corruption – information store does not respond and CPU usage reach up to 100, the information store service of MS Exchange doesn’t start, users are unable to send/ receive emails despite of restarting the information store, unable to stop information store and dependent services, etc. However, the reason for all these issues is probably the corruption in Information store of Exchange.

When the inbuilt utility Isinteg.exe is run and an attempt is made to restore the exchange database then it is probable that the following error message is encountered:

“Error 4294966746: JET_errDatabase Inconsistent”

On the other hand, while mailbox store is mounted using the Exchange system manager, the following error message is cropped up:

Unable to Mount the Mailbox Store with error c104173c “The Information Store is Busy”

Further, to mount database if Exchange System Manager is used the following error message comes up:

“An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.”

Now, for making the Information store completely damage free and corruption free, an Exchange repair tool is required. For this purpose, a third party exchange repair tool works by first scanning the entire store, then repairing it and finally restoring the entire damaged data. One of the best software utility for exchange recovery is Kernel for Restore Exchange.

Kernel for Restore Exchange is a result-oriented and advanced utility that provides recovery of data from corrupt EDB files. It efficiently deals with the checksum errors and dirty exchange shutdown. The most wondrous point is that the software is immersed in an interactive and user-friendly environment that does not require the user to be technically skilled for the software to get operated.

Consider a situation when a user chooses to retrieve the database and the following error messages comes up:

“-1018 (JET_errReadVerifyFailure) The data read from disk is not the same as the data that was written to disk”
“-1022 (JET_errDiskIO) The hardware, device driver, or operating system is returning errors”
“510 JET_errLogWriteFail The log files are out of disk space or there is a hardware failure with the log file disk”

These errors clearly points towards physical corruption of database but still if the user needs to ensure that it really is physical exchange database corruption or not then create an online back-up. This method cross-check every single page of the database and let the user know about any physical damage caused.

In case of confirmation of damage, there are three solutions to get over this harrowing situation:

(i)The already maintained back-up of Exchange database can help create a new database
(ii)Use of inbuilt Eseutil.exe tool with repair option, but it may harm the database by removing the damaged pages
(iii)Perform EDB recovery using third party software

Before performing recovery using third party software, it is necessary to ensure that it should be compatible with the version of Windows and Exchange server which you are using and most importantly that software should be able to maintain the integrity and consistency of EDB data.

Kernel for Restore Exchange is one such eminent third party software tool which performs EDB recovery impeccably by using quick algorithms. After the efficient recovery, the users can access their mailboxes with email data, attachments, images, folders, journal entries, calendar entries, email properties, etc. Moreover, it is embedded with three powerful recovery modes- Automatic analyze and repair, Advance scan and Rebuild Corrupted Database.

In order to restore corrupt EDB, you need a powerful tool that can accurately recover EDB files without losing any important data. Kernel for exchange server recovery tool is the best utility that deals with every Exchange corruption issues and repairs EDB database files. Equipped with advanced QFSCI (quick file system component identification) algorithms, Exchange Server recovery software proficiently recovers deleted as well as permanently deleted mailboxes to retrieve emails, email properties, drafts, sent items, journal entries, calendar entries, notes, zipped attachments and other elements.

In order to solve Exchange server corruption issues and restoring the mailboxes, the Kernel for Exchange Server recovery tool provides three robust recovery modes- Automatic Analyze and Recover, Advance Scan and Rebuild Corrupted Database. The Automatic Analyze and Recover mode is the fastest and simplest repair mode that immediately repairs EDB database files and saves them in Outlook PST files. The Advance Scan mode is used for scanning the EDB database files and creating desired recovered output. The Rebuild Corrupted Database mode is most effective that recovers the data as well as rebuilds EDB database with recovered EDB files.

The trial version of Kernel for Exchange Server recovery tool is available; using which you can analyze its functions and functionalities. The Demo version of Exchange Server recovery utility is fully functional except the fact that it cannot save the repaired EDB to PST files. For saving the repaired EDB file, you are required to purchase the FULL version of the Exchange Server recovery software.

Here are the steps to let you analyze your database for repair:

1.Download and complete the installation process. You can find DRAT at Start -> All Programs -> Microsoft Exchange menu.
2.Click to start it and now you can either let the software to automatically detect your Exchange databases or manually specify the database locations. Unless your server is running an unusual configuration, Auto Detect is the best way.
3.Enter the Exchange server’s name and the name of one of your domain controllers.
4.Click Next and the tool starts collecting server’s configuration. It isn’t actually analyzing the database yet; it’s just detecting the various storage groups set up on your server and the databases within them.
5.On completion of the detection process, choose the storage group containing the problematic database. A screen will appear listing the name of the databases within the store that you chose.
6.Now you can select: Analyze a single database or all databases within the storage group. It’s better to analyze all databases even if the issue is with a single database as all databases in a storage group share a common set of transaction logs, which can sometimes be the root of the problem. If you want quick results, then probably better select the specific database as it takes a while to completely analyze the databases. Select to let the analysis begin.

Once, the process is complete; you get valuable information about the database status and it instructs if any issues were found with the database. It also points to Knowledge Base articles which can be used to revive the server if you can’t mount the database. This utility can be run against Exchange 2000 Service Pack 3 or higher and Exchange 2003. This can get you rid of various errors but what if the EDB files are corrupt. It’s tough to repair them and rebuild the database. In such cases, convert the EDB files to PST files to view them with MS Outlook and recover your data.

Use Restore Exchange Server Database tool to convert EDB to PST files. It repairs Dirty Shutdown error and lets you to mount the databases even when DRAT can’t provide sufficient help. It repairs Priv1.edb database and public folders (pub.edb). It has three recovery modes for complete Exchange recovery; Automatic Analyze and Recover, Advance Scan and Rebuild Corrupted Database. It recovers every mailbox from the EDB database and allows you to save them PST format. It supports MS Exchange Server 5.0, 5.5, 2000, 2003, 2007, 2010 and the PST file created is compatible with MS Outlook 2010, 2007, 2003, 2000, 98 and 97. Use the free evaluation version to restore Exchange and preview the recovered files in PST format but requires the full version to save them in your drive.

Open the Microsoft Exchange Information Store and register the error first. Assure that the Information Store has been stopped before running the Eseutil.exe program. If the information store is not responding then disable it by restarting the server. Now check the consistency of databases with these commands:

C:\Program Files\exchsrvr\BIN>eseutil /mh
“drive:\Program Files\exchsrvr\MDBDATA\priv1.edb”

C:\Program Files\exchsrvr\BIN>eseutil /mh
“drive:\Program Files\exchsrvr\MDBDATA\pub1.edb”

In case you have executed an upgrade then the files would reside at C:\Exchsrvr\Mdbdata folder. Check whether the EDB files are inconsistent or not with these commands:

C:\Program Files\exchsrvr\BIN>eseutil /mh
C:\Program Files\exchsrvr\MDBDATA\priv1.edb > mypriv.txt

C:\Program Files\exchsrvr\BIN>eseutil /mh
C:\Program Files\exchsrvr\MDBDATA\pub1.edb > mypub.txt

If the Public or Private EDB folders are not residing in Program Files folder on the same drive then replace the “C:\program files\mdbdata\priv1.edb” with the full path of the Private and Public EDB files.

Note: If the files are not consistent then perform a soft recovery on the log files with C:\Program Files\exchsrvr\MDBDATA>”C:\Program Files\exchsrvr\BIN\eseutil” /r E00 on the prompt and press yes. If this has not worked then bring the Private & Public EDB files to consistent state:

C:\Program Files\exchsrvr\MDBDATA>”C:\Program Files\exchsrvr\BIN\eseutil” /p priv1.edb
C:\Program Files\exchsrvr\MDBDATA>”C:\Program Files\exchsrvr\BIN\eseutil” /p pub1.edb

Now eradicate all .log files in the Mdbdata folder, .chk filed, and Temp.edb files. Quickly mount and dismount the databases so that other users cannot access them. Defragment the Public and Private EDB files:
C:\Program Files\exchsrvr\BIN>eseutil /d
C:\Program Files\exchsrvr\MDBDATA\priv1.edb

C:\Program Files\exchsrvr\BIN>eseutil /d
C:\Program Files\exchsrvr\MDBDATA\pub1.edb

Now run the Isinteg.exe tool for fixing the private & public EDB databases and restart the information store: C:\Program Files\exchsrvr\BIN>isinteg -s (servername) -fix -test alltests.

If the Information has not been restored then a user can derive the data with restore EDB tool. This is a majestic Restore Exchange tool which retrieves the EDB and STM files from any kind of corruption.

Restore Exchange by using the Eseutil & Isinteg utilities:

Note: Here we have taken the example of Jet Engine Error i.e. Error 4294966746.
The Eseutil utility can be accessed by running the C:\Program Files\Exchsrvr\Bin command. But before using this utility ensure to have at least 20% of spared disk space in exchange database. With Eseutil a user can generate various commands like Defragmentation: /D, Repair: /P, Restore: /C, Recovery: /R, Integrity: / G, File Dump: /M, Checksum: /K, Copy File: /Y, etc. These are the steps for trying it:

Open the information store and register the error or ID messages. Run the Eseutil.exe utility for checking the consistency of Private and Public EDB files. For Private EDB files Run c:\exchsrvr\bin>eseutil /mh…\mdbdata\priv.edb command. For public EDB files run c:\exchsrvr\bin>eseutil /mh..\mdbdata\pub.edb command. After that provide the output in a text file:

• For Private EDB files c:\exchsrvr\bin>eseutil /mh ..\mdbdata\priv.edb > mypriv.txt.
• For Public EDB files c:\exchsrvr\bin>eseutil /mh ..\mdbdata\pub.edb > mypub.txt.

Note: Kindly enter the full path of EDB files.
In case if the files are residing in MBD folders then try the Swift Recovery process.

• c:\exchsrvr\bin>eseutil /r /ispriv
• c:\exchsrvr\bin>eseutil /r /ispub

Now conduct full recovery with the eseutil /mh command then try hard repair for any discrepancy.

• c:\exchsrvr\bin>eseutil /p /ispriv for private EDB files.
• c:\exchsrvr\bin>eseutil /p /ispub for public EDB files.

Also, remove the Temp.edb files in ExchSrvr\Mdbdata. Now check the Microsoft Exchange Information Store service and close the program if they are working normally. Simultaneously run the Defragment (eseutil/d) and repair (Isinteg) command on the private and public EDB files. Repeat this process unless zero error errors are reported.

For avoiding this cumbersome process and saving time use the reliable Exchange Server Recovery software. This restore EDB tool can quickly restore the corrupt and damaged EDB files into accessible PST files.

By making the proper usage of restore exchange software one can easily deal with every situation very easily. However, you can also get ride of such situations or corruption even by using in-built data recovery tools. In fact, MS Exchange Server provides user with two different repair tools- Eseutil and Isinteg. Both these utilities are effective and facilitate you perform Exchange Server Recovery operation in an easiest manner. These in-built programs repair and restore the
Database that has got corrupted, but you may surprise to know that there are conditions when these utilities fail completely to deliver the desired result. In fact, in situation of severe database damage the programs fail to perform its operation. To deal with such unfavorable conditions the most effective approach that you can opt is MS Exchange recovery software like Exchange Server Recovery tool. The tool is very efficient and can be very useful for repairing the deleted Exchange mailboxes as well as the permanently deleted emails from the mailbox folders.

There are many who also recommends opting the manual data recovery process to restore Exchange database. But, it’s just not that easy as it appears initially. Adding to this, a manual MS Exchange database recovery process is a very expensive and time-consuming method. The probability to retrieve the required information with full accuracy is very less. Therefore, it’s important that you take help of this third party Exchange Serer Recovery tool. It is very easy and safe to use.

All that a user needs to do is just provide the file path. And, once you provide the complete path the software will do rest of the work. In fact, the most important highlight of this tool is its interactive graphical user interface that assists user in having quick data recovery.

Microsoft Exchange Server saves all the received, sent emails in an EDB database file which faces corruption due to physical hard drive errors, jet errors and file size errors. Also, exchange server failure occurs at times due to improper shutdown, virus attacks and human errors. Recovery for Exchange Server restore Exchange Server email database i.e., .EDB and .STM files. It efficiently converts .EDB files to working .PST files through which emails of MS Exchange Server can be viewed with Microsoft Outlook email client. It also recovers inaccessible and deleted emails from MS Exchange Server database files.

Key features:

Let’s have a brief look at its elaborate features.

• Use it to restore exchange server data and save user mailbox to .PST or .EDB file
• Restores various items of mailbox including emails, attachments, images, contacts, appointments, tasks, etc
• Also recovers inaccessible and deleted emails from MS Exchange Server database files.
• Repairs Dirty Shutdown error where eseutil and other ms utilities fail
• Efficiently repairs large databases.

Most of them support email recovery from all the versions of MS Exchange Server 5.0, 5.5, 2000, 2003, 2007 and 2010. Also normally support Microsoft Outlook 97, 98, 2000, XP, 2003, 2007 and 2010. Generally they come with a free trial version for scanning and viewing the recoverable data and the full version is used to actually retrieve them.

Exchange Server Recovery:

Nucleus technologies also provide Restore Exchange database software but with added features. It has three recovery modes; Automatic Analyze and Recover, Advance Scan and Rebuild Corrupted Database. Use them accordingly to recover data with the most appropriate way. Software is available in two different licenses, corporate and technician license depending on how many files you need to repair.
