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.

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.
