100% Reliable Utility to Recover Mailboxes From Severely Corrupt Exchange Server Database

Exchange Servers help organizations in storing their email transactions rather being dependent on private mail servers, like gmail, yahoo or rediffmail. The Exchange database stores all the user mailboxes of the entire organization. With many business critical email transactions, including emails, contacts, notes, calendar entries etc, if the Exchange Server database encounters any problem, all the data in it becomes completely inaccessible. However, do not worry, there are many Exchange Server recovery software available in the market with which you can repair the corrupt Exchange Server database and recover your inaccessible data back.


Usually, due to virus infection, file system corruption, operating system problem or contradiction with any installed hardware/software, the Exchange Server database gets corrupt. The application event log of the MS Exchange Server contains all the entries of the events along with corresponding error reports. From the error reports, you can get to know about the exact reason behind the Exchange Server corruption.

Below is an error message that you may encounter, if your Exchange Server 2000 has been corrupt:

“Date: Date
Source: ESE
Time: Time
Category: Database Corruption
Type: Error
Event ID: 448
User: N/A
Computer: ServerName
Description: Information Store (2412) Data inconsistency detected in table Msg of database E:\Program Files\exchsrvr\mdbdata\priv4.edb (0,524957).”

In case of the above error, if you check the problem by running ‘eseutil/g’, the Exchange Server displays another error message as below:

“The Database is corrupted.”

As it is quite clear that the Exchange database has been corrupt, you need to study the event log carefully to get at the exact solution. Here, you can follow the below procedures to resolve the above Exchange Server problem:

• If you think that the problem is due to any faulty driver or hardware, try to locate it and resolve by changing the faulty hardware. Also, update the required drivers.

• If the problem persists and you are running the information store, you need to move the data from the Exchange database to a new database. In order to do this, first use the 'Exchange Mailbox Merge' utility to export mail objects to PST files. After this, delete the corrupt database, create a new database and move data to the newly created blank database by using ‘Exmerge’ command.

If the problem is still there, try to restore data from a previously created valid backup. If you do not have any recent backup of the Exchange database, immediately opt for any Exchange Server Recovery software.

Stellar Phoenix Mailbox Exchange Recovery is one of the advanced Exchange recovery software to repair severely corrupt Exchange database and recover all the mailboxes back. The software is completely reliable and with 100% read-only recovery process, it recovers the mail objects in their original format.

How to repair and recover damaged database files in Microsoft Exchange Server?

Microsoft Exchange server is considered to be one of the best and fastest email server applications in the world. An Information Store is very important and essential component of the MS Exchange server that is used to store both Mailbox and Public store data. The Information store uses Exchange database files to effectively manage the stored users’ data. An Exchange database file tends to be damaged or corrupted due to various reasons like sudden server down, hardware failure, abrupt exit from Exchange Server. As corruption of database file is an unwanted hurdle that halts the smooth working of an organization so it is essential to find the root of cause and take the effective method to solve the issue. Microsoft has provided some built-in tools that can be used to solve the corruption issues. If these built-in utilities are not able to repair your damaged database file, then you can use a third-party Exchange recovery program to do so.

When an Exchange database file gets corrupted, it becomes impossible to mount the Information store in Exchange Server. Additionally, various error messages may appear on the window. Following are few symptoms which show that the information store database may be damaged:

How to resolve the issues:

Following are few ways which can be used to work around the problem:

A) Restore from backup: If you have clean and updated backup file, you should restore the database with its.

B) Run ESEUTIL utility: To repair the corrupt database file, Microsoft offers ESEUTIL command line tool. So, if the backup file is either not clean or not updated, then you should use this built-in repair application.

Note: When Eseutil /p (a hard repair command) utility is used to perform database repair, it removes anything it fails to understand. i.e you may experience some data loss situations after using it. Moreover, there is no method to identify how much your data is going to be lost.

C) Run ISINTEG utility: After running the ESEUTIL repair tool, you should run the ISINTEG utility. This command line tool helps to rebuilds and fixes the errors occurred in the information store after repair and restoration.

However if the Exchange database file remains inaccessible even after trying above said methods, then try to recover Exchange database using a third party Exchange server recovery software. Such tools are specially designed for this purpose. Stellar Phoenix Exchange Recovery is one such highly useful application that successfully repairs and recoups all data from damaged Exchange Server in only three simple steps.

How to Solve Corruption Issues in Microsoft Exchange Server?

Data stored in Exchange server application are represented with the help of EDB files. The EDB file contains all data in the form of user mailboxes which are accessed through MS Outlook email client. While working with your Exchange mailbox, sometimes you get unexpected error message and all the data becomes unapproachable. This kind of problem can be occurred when the Exchange database file gets corrupt. Numerous reasons are responsible for such behavior. But it is feasible to sort out the issues related to corruption by appropriate inbuilt repair methods. If by using these methods, you do not get any results, then it is better to go for a third party Exchange recovery tools.

For further clarification of above topic. Let's for say, you use Exchange server application. On one day, when you are working with Exchange Server and make an attempt to access the Exchange mailbox data. You fail to access them. Additionally, you receive an error message that looks like this:


“1067 The information store terminated abnormally”

When you perform online defragmentation of Exchange database file, below mentioned event is logged into Event Log:

Date: date Source: ESE
Time: time Category: (12)
Type: Error Event ID: 447
User: N/A
Computer: Servername

Description:
Information Store (nnnn) A bad page link (error -327) has been detected in a
B-Tree (ObjectId: 19, PgnoRoot: 113) of database E:\Program
Files\Exchsrvr\mdbdata\priv1.edb (3440582 => 3443648, 3443232).


Cause:

The most probable causes for the occurrence of above error are:

i) Hardware failure
ii) An antivirus application is trying to scan the directory of Exchange database file.
iii) Logical structure of the database file has become damage or virus infected
iv) During Exchange server database restoration process, correct log files were not replayed.

As logical corruption in Exchange database file cannot be detected by the backup utility, you may not be aware of the issue during the backup. This problematic issue only encounters when your attempts to access the database page where the damaged data is store.

Whatever be the reason behind this problematic issue, the potential for precious data loss would be high. Since database file corruption is a grave situation, you are required to fix immediately it by using effective Exchange repair steps.

Solution:

For solving the above problem, and for Exchange data recovery, try any of the following methods:

1) Restore from Backup: You can restore the database from the backup that was taken just before this error encountered.

2) Hard Repair (Eseutil.exe /p): If you do not care about precious data, then you may try this method to repair damaged information store database. It is a destructive utility and you may experience some data loss after running it.

3) Third party applications: If you do not want to use above said methods or you don’t have updated backup copy, you can opt for third party Exchange server recovery software like Stellar Phoenix Exchange recovery.

What to do when encountered with Exchange Server Error -1216

Exchange database and transaction log files are cardinal elements to keep the Microsoft Exchange Server running. Often times, either deliberately or unintentionally certain hardware or software issues occur that can cause removal of those critical files.

Exchange Error -1216 is encountered when the critical database and transaction log files are missing or there has been a replacement with different versions. When the Exchange EDB file is accessed, the server compares the EDB file header with the transaction log files. If some of the files are found missing or removed, then Error -1216 is registered.

Grounds of the Problem:

Exchange Server application has their files namely, database files, transaction log files and a checkpoint file. Each of these files has a header that contains information regarding the relationship of that file with all the other files in a storage group.

Sometimes owing to unfavourable circumstances like power failure, the Exchange database is shut down abruptly. After a dirty shutdown when Exchange Server compares the file header of database and transaction log files, it observes abnormalities and generates Error -1216.

Workaround:

The workaround for this error is to perform Exchange Server Repair using inbuilt utility ESEUTIL. However, one important thing to be kept in mind prior to doing this is that after the database recovery is complete, the missing information cannot be re-integrated. Unless you are certain you have all the vital data you require, do not use this utility.

After you have verified the above point, perform database recovery using the following command:

ESEUTIL /R Enn /I /L[log_path] /S[system_path]

A point to note here is that sometimes the database is in an inconsistent state and some of the critical log files are missing. Under this situation, soft recovery will not be able to perform Exchange Server Repair. Hence, either the data needs to be recovered from a backup or repaired by first running ESEUTIL/P command, then ESEUTIL/D command and lastly ISINTEG- FIX command.

If this doesn't help, then Error -1216 can be avoided by removing all the transaction log files. As long as there are no log files, the Server will not analyze the file headers and thus the problem can be resolved. Take the backup of the entire storage group before attempting this. Once done, a new set of transaction log files can be created.

It might be possible that none of the measures to work around this problem helps. If you are in the same situation, then there is no need to worry. Professional tools such as “Stellar Phoenix Mailbox Exchange Server Recovery” are available that can successfully perform Exchange Recovery. The software uses advanced algorithms to recover all the data from the Exchange EDB file and restores the emails, contacts, notes, calendar entries etc. intact. This adroit tool is compatible with Exchange 2010, 2007, 2003, 2000 and 5.5.

How to perform Exchange Recovery to resolve the database corruption issue?

No matter large or small organizations, most of them use Microsoft Exchange Server as an email server application for their effective communication and management. As you know, emails are an essential part for every company because it is the best way to communicate with the clients worldwide.

Since Microsoft Exchange Server is flexible, secure and very much user friendly that is why it is becoming famous in the corporate world, but everything has some limitations. Exchange Server also has few limitations and sometimes gets damaged or corrupted due to some errors such as virus attack, hardware failure, operating system malfunction, abnormal termination of the information store service and many more.

Corruption in Exchange server is a subject to take seriously because it may be the cause to lose all important data from the information store database. Some error messages also appear on the screen when Exchange Server database gets corrupted. To resolve such problematic issue, we need to perform recovery of Exchange Server. Two types of recovery methods are provided by the MS Exchange server:

1) Soft Recovery: - This method is used to bring the database into consistent state.

2) Hard Recovery: - This repair process is applied when soft recovery process does not work and there are corruption issues in database files. The hard recovery process is carried out by using two following inbuilt utilities:

      i) ESEUTIL/p Utility: - It is a command line repair utility that repairs the header of the damaged database file. It is a destructive utility and removes to corrupted database pages to bring the database into consistent state. As it removes the corrupted data from the database, users sometimes experience their precious data loss issues. So, it is highly recommended to make a backup of database before running this repair tool.


      ii) ISINTEG Utility: - This utility is run after completion of eseutil /p repair process. This utility verifies that the database is now error free and ready to mount.


Note: - There are some limitations of these free utilities:


* Only applicable to handle minor corruption problems.
* Chances of important data loss are high.

In order to make database completely corruption free and to avoid the data loss situations, there are some advance third party Exchange recovery programs like Stellar Phoenix Exchange recovery software that efficiently handle all corruption problems and recover Exchange database data upto 100 % from damaged database.

Stellar Phoenix Exchange Server Recovery is an efficacious application that efficiently performs EDB recovery in few steps. The demo version of the software can be downloaded from the website directly that offers a preview of data stored in damaged database file.
