Microsoft Exchange Recovery Tool

When you start Microsoft Exchange Server database, you might come across Error -1216. This error shows that the Microsoft Exchange Server has concluded that that files in EDB (Exchange Server Database) file’s running set are lost or the files have been reinstated with different versions. In such situations, the EDB file may get damaged and you need to go for Exchange Server Recovery to sort out the issue. Error -1216 may be shown in the following format:

“Error -1216 (JET_errAttachedDatabaseMismatch)”

This error can also be symbolized in the hexadecimal format as ‘0xfffffb40’. When you encounter this error, Microsoft Exchange Server aborts the soft recovery process on EDB file, prior to make some changes in the database that might prevent you to re-integrate the missing database files with data set.

When this error occurs, you should try restoring the missing database files. When such files are not available, use Eseutil tool to override the error and continue with Exchange Server Repair. When this error occurs, you might find the following entries in the application event log of Exchange Server:

“Event Type: Error
Event Source: ESE98
Event Category: Logging/Recovery
Event ID: 0
Date: 4/24/2001
Time: 6:20:18 PM
User: N/A
Computer: EXCHANGE1
Description: Information Store (4312) Database recovery failed with error -1216 because it encountered references to a database, ‘D:\exchsrvr\mdbdata\PRIV2.edb’, which is no longer present. The database was not brought to a consistent state before it was removed (or possibly moved or renamed).

The database engine will not permit recovery to complete for this instance until the missing database is re-instated. If the database is truly no longer available and no longer required, please contact PSS for further instructions regarding the steps required in order to allow recovery to proceed without this database.”

This behavior of Exchange Server generally occurs when the assessment of header information in database and log files indicates that the replacement or deletion of some vital files has been done. If you run soft recovery, entire database might get damaged.

No matter what the cause of this issue is, the ultimate result would be the loss of your mission critical data. In such situations, Exchange Server Recovery is required to repair and restore damaged database. This is best possible using powerful and advanced third party tools, known as Exchange Server Repair software.

Stellar Phoenix Mailbox Exchange Recovery is the most advanced and effective tool to retrieve data from damaged Exchange Server. This software can repair and restore EDB files of Exchange Server 2003, 2000 and 5.5. It is compatible with Microsoft Windows 2003, XP and 2000.

Microsoft Exchange Server is an important part of a collaborative and messaging environment. Due to the importance of Exchange Server database and stored data, you should regularly back it up. But in some situations, when you attempt to backup EDB (Exchange Server Database) file, the process gets terminated halfway due to corruption to EDB file. In such cases, you need to first perform Exchange Server Recovery to sort out the issue to gain access of your mission critical data.

Sometimes when you attempt to create backup of Microsoft Exchange Server database, which is damaged and inaccessible, you might come across the below given error message:

“Database or database element is corrupt”

Furthermore, with this error message, you might also get a statement, which states that this file can not be verified. Due to corruption, the Exchange Server can not recognize the database and thus can not access it. At this point, you need to identify the cause of data loss and carry out Exchange Server Repair by sorting it out.

Root of the issue

As stated in the above error message, this situation occurs due to corruption to the EDB file. The corruption could be the possible result to virus infection, accidental system shutdown, application errors, operating system malfunction and other similar reasons.

Resolution

In order to fix this issue, you should go for Eseutil/p utility. This is an inbuilt tool in Microsoft Exchange Server that is used to repair damaged EDB file. This tool scans the damaged database and can repair in a number of cases.

Although, this utility is helpful in resolving this error message, but it also has a downside. It deletes all of the database elements that are not recognized by this tool. This behavior of Eseutil tool cause critical data loss situations and make your data permanently inaccessible. To safely retrieve your critical data, go for advanced and powerful Exchange Server Recovery software.

These software are particularly designed to safely, smoothly and thoroughly scan entire database and retrieve all of the inaccessible database objects. These software use efficient and powerful scanning algorithms to achieve perfect Exchange Server Repair. With interactive and simple graphical user interface, such applications are easy to use and do not require sound and prior technical skills.

Stellar Phoenix Mailbox Exchange Recovery is the most advanced and effective software that can handle all EDB corruption scenarios. It can repair and restore damaged EDB file of Exchange Server 2003, 2000 and 5.5. This software is compatible with Windows 2003, XP and 2000.

Microsoft Exchange Server is the most important application to create a collaborative messaging environment. It stores all of the critical user information in Exchange Server Public Information Store. The Exchange Server database contains a separate mailbox for every user and an exact copy of the mailbox is stored on the user hard drive in the form of OST file. In some cases, the Exchange Server database may get damaged due to virus attack or other similar reasons and you need to opt for Exchange Recovery to sort out this scenario.

Sometimes, when you attempt to mount the Exchange Server database (EDB file), you might come across any of the following events in the Application Event Log of Exchange Server:

Event Type: Error
Event Source: ESE
Event Category: General
Event ID: 505
Description: Information Store (2028) An attempt to open the compressed file “drive:\Exchsrvr\MDBDATA\priv1.edb” for read / write access failed because it could not be converted to a normal file. The open file operation will fail with error -4005 (0xfffff05b). To prevent this error in the future you can manually decompress the file and change the compression state of the containing folder to uncompressed. Writing to this file when it is compressed is not supported.

Or

Event Type: Error
Event Source: MSExchangeIS
Event Category: General
Event ID: 9519
Description: Error 0xfffff05b starting database “First Storage Group\Mailbox Store (EXCHANGE)” on the Microsoft Exchange Information Store. Failed to attach to Jet DB.

This issue generally occurs when you upgrade to Exchange Server 2000 Service Pack 3 or later and the Information Store database is compressed using NTFS (New Technology File System) file system compression. Under some situations, NTFS compression may damage the Exchange Server database like when the EDB file exceeds 4 GB size. In such cases, Exchange Repair is required to work around the issue.

Exchange Server 2000 Service Pack 3 and later do not allow NTFS compressed information store to mount. The files are managed by Extensible Storage Engine (ESE) that needs sector independence for log-based recovery that is not allowed in compression.

This entire behavior of Exchange Server corrupts the EDB file and you are required to repair and restore is using Exchange Recovery software to access your critical data. These software can recover all of the Exchange Server database objects.

Stellar Phoenix Mailbox Exchange Recovery is the most advanced Exchange Repair software that works in most of EDB corruption cases. It works well with Exchange Server 2003, 2000 and 5.5. This software is compatible with Microsoft Windows 2003, XP and 2000.
