Microsoft Exchange Recovery Tool

exchange recovery

Like other databases, Microsoft Exchange Server database (EDB file) may also corrupt at some point of time and does not let you perform typical Exchange Server operations. The corruption can be of two types – Logical and Physical. Logical corruption is pretty common and occurs due to internal fault in the database. When it happens, Microsoft Exchange Server database becomes totally unusable and you encounter serious data loss. MS Exchange Server does not include any utility to detect and fix logical corruption. Thus, you are required to opt for Exchange Recovery to get your valuable data back.

You may encounter logical corruption of EDB file due to any of the following reasons:

1.If you incorrectly run the soft recovery using eseutil /r tool after restoring database from an online backup, it replays only log files and ignores the patch files. It may result in logical corruption. Extensible Storage Engine 98 does not let you run the soft recovery on an EDB file that needs hard recovery. In case you try this, the following Jet error appears in Application Event Log of Exchange Server:

“JET_errSoftRecoveryOnBackupDatabase (-544)”

2.If you initialize an inconsistent EDB file, the process checks whether that log range specified in database header is there in directory of log, and signatures of both log and database are correct. In case it does not find the specified values, it logs the below event:

“JET_errRequiredLogFilesMissing (-543)”

3.The database may also face logical corruption if you run eseutil /p utility. Jet-level Exchange Server database repairs result in some inefficient disk space uses and data loss, because it fixes the EDB file by deleting the corrupt data.

Resolution

To fix this problem and ensure effective Microsoft Exchange recovery, follow the underwritten steps:

1. Defragment the database using eseutil /d command and then run database integrity check using Isinteg -fix command.
2. Restore corrupt EDB file from the most recent backup. You should not run the soft recovery after restoring from backup as it may cause further damage.
3. Use third party Exchange recovery software to repair and restore the problem database.

The Exchange recovery tool is particularly designed to perform in-depth scan of entire EDB file and extract all inaccessible data from it. They offer simple and secure Exchange Server Recovery due to their rich graphical user interface and non-destructive nature.

Are you facing problems in accessing mailbox folders in MS Exchange Server 2000? Usually, such things happen when some internal settings for the mailbox store are not correctly set. Also, it may also be possible that the mailbox folder itself has got corrupted. Such corruption can occur due to various reasons such as abrupt or improper system shutdown, database header corruption, corruption of transaction log files, etc. In such cases, you should try to resolve the issue using appropriate corrective measures. In you are not able sort the issue, then you should use a third-party Exchange Recovery software to repair MS Exchange Server mailbox store.

Consider a scenario wherein you are unable to mount an MS Exchange Server 2000 mailbox store using Microsoft Exchange System Manager. 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”

In addition, either or all of the following event IDs will be logged in the Application event log as well:

1. Event Type: Error
Event Source: MSExchangeSA
Event Category: MAPI Session
Event ID: 9175
Description:
The MAPI call ‘OpenMsgStore’ failed with the following error: The attempt to log on to the Microsoft Exchange Server computer has failed. The MAPI provider failed. Microsoft Exchange Server Information Store ID no: 8004011d-0512-00000000

3. Event Type: Error
Event Source: MSExchangeIS
Event Category: General
Event ID: 9519
Description:
Error 0×80004005 starting database “First Storage Group\Private Information Store (servername)” on the Microsoft Exchange Information Store.

Cause:

The root cause of this problem is that the System mailbox object exists in the System Objects container, which is created for this mailbox store. And when you try to mount it, Exchange Server creates another object for the same, which is causing the problem.

Resolution:

To resolve this issue, you should perform the following steps:

1.Start the Active Directory Users and Computers snap-in.
2.Click the Advanced Features option in the View menu.
3.Find the Microsoft Exchange System Objects container, and then look for the System mailbox object whose mailbox store you were trying to mount.
4.Delete the System mailbox. Now try to mount the mailbox store. It should run fine now.

However, there are few instances when the problem is not resolved using these steps. In such cases, you should use a third-party Microsoft Exchange Recovery software. Such read-only tools are highly interactive and user friendly in nature that ensure safe and secure Exchange Server recovery.

Microsoft Exchange Server lists all the transaction, which you performed on the server, in Transaction Log File. It helps you to find out the details about failed transactions and fix the particular problem. There are some cases where the transaction log file of MS Exchange Server may corrupt and leave your database in unusable state. In case of transaction log file corruption, you may not mount the database and encounter critical data loss situations. At this stage, Exchange Server recovery is the only way to get your precious data back.

For instance, you may run across the below error message when you attempt to mount an Exchange Server mailbox or public store after log file corruption:

“An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both. ID no: c1041724”

At the same time, you may see any of the below events in Application Event Log of Microsoft Exchange Server:

1. Event ID: 465

2. Event ID: 454
Source: Ese98
Type: Error
Computer: Server1
Information Store (2184) Database recovery/restore failed with unexpected error -501.

Subsequent to the above errors, you cannot mount the database and access stored data from it. In order to gain access of your valuable data, you must fix this problem through Microsoft Exchange recovery solutions.

Root of the problem:

This behavior generally occurs due to log file corruption or Exchange Server public store corruption. In both the situations, database can not be mounted and accessed.

Resolution:

You need to remove the log file and reboot Exchange Server, if problem is caused by log file corruption. On the other hand, if public store corruption is causing this behavior, you need to repair database using Exchange recovery software. The Exchange recovery tools successfully handle all corruption scenarios.

DB file), which can be accessed using Microsoft Outlook Email client. You should regularly backup EDB file to prevent any sort of data loss situations, if database is damaged. However, under some circumstances, Exchange Server database an not be accessed after restoring from a backup. The database restores properly, but you encounter errors while trying to access it. This behavior leads to critical data loss and needs Exchange Server recovery to be sorted out.

For instance, you may come across any of the following behaviors after restoring the Exchange Server database from current backup:

1.You manage to restore the EDB file, but it single. There is no catalog data or transaction log file.
2.The Eseutil /p utility runs successfully on corrupt database, but it cannot be accessed.
3.You cannot check the state of your Exchange Server database using Eseutil /mh utility.
4.You get the following errors while checking the state of restored database:

a) Initiating FILE DUMP mode…
Error: Access to source database ‘c:\mailbox database.edb’ failed with Jet error -1022.
b) Operation terminated with error -1022 (JET_errDiskIO, Disk IO error) after 0.203 seconds.

When this behavior occurs, Exchange Server database becomes totally unusable and inaccessible. You encounter same behavior every time you try to open the database. In order to gain access of your valuable data, you need to figure out the root of this issue and perform Microsoft Exchange recovery by fixing it.

Cause

This behavior occurs due to missing log files or corrupt backup file. In both the cases, Exchange Server cannot access the source database and you face this issue.

Resolution

You can try resolving this problem using Eseutil /p command line tool or by restoring the database again from backup. If possible, move unaffected files from problem database to new database.

If the above method does not work, you need to repair and restore corrupt Exchange Server database using advanced and powerful third-party applications, known as Exchange recovery software.

In Microsoft Exchange Server, you must replay the log file after restoring your EDB (Exchange Server database) from an online backup. This process is known as Hard Recovery. It helps you to recover your Exchange Server database in case of database corruption or database failure. However, in some situations, the Exchange Server hard recovery fails and the database remains in inaccessible and unusable state. At this point, you need to repair and restore the corrupt database using advanced Exchange Server Recovery tools.

As a practical example of this problem, the hard recovery of Exchange Server with Eseutil /cc may fail and you come across the below error message:

“Operation terminated with error -939523485 (Existing log file is not contiguous.) after 0.481 seconds.”

At the same time, you may see any of the following Events in the Application Event Log of Microsoft Exchange Server:

Root of the problem:

You may come across this problem if the old log files are not in sequence with log, which is mentioned in the Restore.env file. You can file all the required log files using Eseutil /mh utility.

Resolution:

To fix this problem, follow the below steps:

1.View the content of Restore.env file using Eseutil /mh utility.
2.Record range of log files.
3.Remove the log files that are out of range.

If the above method does not work, you need to repair and restore the damaged Exchange Server database using third-party Exchange recovery software.

Are you unable to write data to Microsoft Exchange Server database? Is your EDB (Exchange Server database file) inaccessible? This behavior may occur due to either low disk space on Exchange Server computer or corrupt EDB file. If the database is corrupt, you need to restore it from the most recent backup to prevent data loss situations. However, in case backup is not valid or updated, you need to opt for Exchange Recovery solutions to retrieve data from the database.

In a practical scenario, the Information Store Service of Exchange Server may fail to start and you encounter the below errors in Application Event Log of Exchange Server, while read/writing data from/to EDB file:

“Event Type: Error
Event Source: ESE
Event Category: General
Event ID: 482

It restores inaccessible objects of EDB file, such as emails, notes, tasks, contacts, journal, calendar items, and more.

In Microsoft Exchange Server, when you access data from the Exchange Server Database (EDB) file, it is mounted after running Information Store Service. Mounting is the process of making the database available for all services running under Exchange Server environment. However, under some circumstances, the EDB file refuses to mount and it remains inaccessible. The problem may occur due to numerous reasons, including database corruption. This behavior results in severe data loss and requires Exchange Recovery if there is no backup in place.

While mounting the Exchange Server database on server, which is running MS Exchange Server, you might encounter the below error message:

“An internal processing error has occurred. Try restarting the Exchange System Manager or the Microsoft Exchange Information Store service, or both.
ID no: c1041724

In all the above situations, you need to use Exchange Recovery Software to repair and restore the damaged database.

Exchange Recovery Tool is specifically designed to carry out in-depth scan of entire Exchange Server database and extract all inaccessible data from it. They ensure absolute, simple, secure, and quick Microsoft Exchange Recovery in all cases of EDB file corruption.

Stellar Phoenix Mailbox Exchange Recovery software repairs and restores damaged Exchange Server database in all cases of corruption. The Exchange Server Recovery software works well with Microsoft Exchange Server 2007, 2003, 2000, and 5.5. It restores all EDB file objects, such as emails, notes, contacts, tasks, calendar entries, journal, and more.

Is your Microsoft Exchange Server’s Information Store damaged and does not start? Are you unable to retrieve information from EDB (Exchange Server Database) file? The information store corruption is due to numerous reasons, such as improper system shutdown, faulty hardware, virus infection, or application malfunction. In such situations, you need to opt for Exchange Server Recovery to access your database.

To recover Microsoft Windows Store that doesn’t start, use the below methods:

• Check Application Event Log of Windows NT Event Viewer for MSExchangePub, MSExchangePriv, EDB, and MSExchangeIS messages. The messages may provide you information about actual cause of the problem.
• Shut down all the MS exchange Server services, and then restart Exchange Server. When information store service restarts, it attempts to recover automatically and return database to consistent state.
• Create an absolute backup of Microsoft Exchange Server Information Store. It must include all the EDB and Log files.
• Restore database from last complete online backup. Make sure that you don’t click to choose ‘Start Service after Restore’ option. Restore incremental backups of Information Store. Only click selecting ‘Start Service after Restore’ option while restoring current incremental backup. Do not select ‘Erase all existing data’ option.
• If the above method can not help you start information store, check Event Log and review logged messages for EDB.
• If the above method doesn’t work, restore online backup of information store. Select ‘Start Service after Restore’ and ‘Erase all existing data’ options.
• Remove all the Log and EDB files from Mdbdata folder and then restore copies of Pub.edb and Priv.edb databases from backup.
• If none of the above methods work, you need to wipe the information store as last resort.
• If wiping does not work, you need to remove the Information store. However, it causes data loss. The easiest and safest way to retrieve data in such situations is Microsoft Exchange Recovery.

Recovery is possible using powerful and advanced third-party applications, known as Exchange Recovery Software. The applications are able to handle all EDB corruption situations, irrespective of the cause of corruption.

The Exchange Recovery Tool employ efficient database scanning techniques to methodically scan whole EDB file and extract damaged objects from it. With simple graphical user interface and read-only conduct, the applications are easy and totally safe to use.

Exchange Recovery software is the most advanced utility to recover your Exchange Server database from corruption. It works well with Microsoft Exchange Server 2007, 2003, 2000, and 5.5. The software restores all EDB file objects such as emails, notes, contacts, tasks, appointments, attachments, and more.

Microsoft Exchange Server’s most fundamental component is transaction log, and Exchange Server writes all the transactions to these log files and applies these written changes to the database, when the system permits. On starting Exchange server, when the Information Store comes online, ESE checks the consistency of the database, and in case of detection of inconsistencies, ESE replays the transaction log files to locate those transactions that have not been applied to the database. In Exchange Server terminology, this process is termed as ‘Soft Recovery’. There can be many situations when a soft recovery is being done and database is damaged. To determine if this problem actually exists or not, you can view the application event log and perform Microsoft Exchange Recovery procedures accordingly.

As an instance of such Exchange Server problems, suppose you try to restore the Information Store database, but it cannot be completed. Additionally on viewing the application event log, you receive the following event ID:

Event Type: Information
Event Source: ESE
Event Category:
Event ID: 301
Date: date
Time: time
User: N/A
Computer: server_name
Description:
<process name> (<process id>) <number> The database engine has begun replaying logfile [path]\[logfile name].
For more information, click http://search.support.microsoft.com/search/?adv=1.

It can be observed with both, Exchange-aware restore and offline restore of Information Store database. This event ID suggests that Exchange Server database engine has started replaying the log files indicated by [path]\[logfile name], where ‘path’ is the full path and ‘logfile name’ is the name of logfile being replayed. Not always, but event 301 many a times indicates that the Exchange Server database is corrupt.

Resolving Event 301

Generally, you need not take any action to isolate the issue. But you should check the application event log to determine more issues that are possible when starting the database. Check the log report for damaged or missing log files, if any and hence know the root of failure.

If you find any event that indicates database corruption, the further attempts should be done to restore the database. You can either restore it from the last backup available or repair the database by Exchange repair utilities or use a third-party Exchange Recovery Tool.

A Microsoft Exchange Recovery software can scan a corrupted Exchange database and restore its contents at a safe location. With their interactive design, you can find these utilities easy to run and use.
