How To Solve Table Index Corruption In Exchange Server

  • Posted on July 14, 2017 at 5:31 pm

The main repository of mailbox data in Exchange Server is the .edb file that is primarily composed of b-trees. Since a b-tree is allowed to have a considerable depth, b-trees deploy indexes to permit quick data access. In Exchange EDB, there are few ancillary trees that hold table indexes to work with the main tree. If these indexes go corrupted, the entire table and sometimes, the whole database become unusable. This is what we refer as logical database corruption. In critical situations, when this type of corruption is not limited to index page corruption, you need to implement Exchange Server Repair solutions.

To understand such potential problems with Exchange database further, consider the discussed scenario and error. When using Exchange Server 2007, you can encounter event 467 logging in the application log. Additionally, on viewing the description section of the same event, you receive an error that reads similar to below:

Information Store (number) Index [index name] of table [table name] is corrupted.

This error typically indicates a corrupted index in the Exchange store. As symptoms, you might observe access violations and repeated crashes. Also, this type of corruption might go undetected for long without any symptoms. Even the Exchange-aware backup may fail to detect this corruption. Event 467 suggests logical corruption at Database (JET database engine) level and is exhibited when JET engine touches this location in the database while reporting it as event 447. For specific root causes, one needs to view the application and system log cautiously as these errors can damage your data badly.

Solution

Following suggestions can help you isolate the depicted problem:

1. If corruption is limited to index leaf pages and not with the database pages, running Eseutil /d (offline defragmentation) alone can perform Exchange Server Repair.

2. In critical problems, you may need to use ExMerge utility to move the mailboxes to a new, blank Information Store.

3. The Exchange Server might be affected from page or database level corruption together with index page corruption. In such cases, you can execute Eseutil /p and then Isinteg -fix commands as Eseutil /d command may not work. You can further use ExMerge tool to put the database again in use.

4. To avoid data loss problems due to Eseutil /p utility, it is however, recommended to opt for a safe third-party Exchange Repair utility.

The Exchange Repair is a professional utility that repairs corrupted Exchange EDB file and restores the mailboxes in separate *.pst files. The Exchange Server Repair product is easy to use with its self-explanatory interface. Designed for Exchange Server 5.5, 2000, 2003, and 2007, the tool is also competent to recover deleted mailboxes.

Iis Metabase Corruption May Cause Exchange Server Database Corruption

  • Posted on July 14, 2017 at 7:11 am

Microsoft Exchange Server is a well-known application that is used to create collaborative messaging environment. It is installed on server and can be accessed from client computer using Microsoft Outlook. Exchange Server 2003 and Exchange Server 2000 use MS IIS (Microsoft Internet Information Services) to provide Exchange-related services. All configuration settings of the IIS are stored in IIS metabase. The formation of metabase contains various settings of properties of different nodes. However, in some situations the metabase may get damaged and cause critical EDB (Exchange Database) corruption scenarios. To sort out this problem, you need to opt for Exchange Server Recovery, in case of unavailability of backup.

Corruption of IIS metabase and Exchange Server database is a very serious concern. It can cause several Exchange Server vulnerabilities and make Exchange-related services unusable. In case of metabase corruption, you may encounter the below error message:

[15:52:34] – The Internet Information Server metabase appears to be corrupt. Please uninstall and reinstall Internet Information Server. — ID:62145 —
[15:52:34] Prerequisites for Microsoft Exchange Messaging and Collaboration Services failed: The component ‘Microsoft Exchange Messaging and Collaboration Services’ cannot be assigned the action ‘Upgrade’ because:- The Internet
Information Server metabase appears to be corrupt. Please uninstall and reinstall Internet Information Server.

The above error, in particular, occurs due to missing metabase entries. If various users perform transactions after metabase corruption, the EDB file may encounter several inconsistency issues. In such situations, to bring your Exchange Server in working state, you need to fix this behavior using Microsoft Exchange Recovery Tool.

Resolution

You can use Adsutil.vbs, an inbuilt utility of Microsoft Exchange Server, to locate metabase objects. However, if you encounter the following error while using Adsutil.vbs tool, you have to reinstall Internet Information Service and Microsoft Exchange Server:

-2147221020 (0x800401e4)
Error trying to enum the object (GetObject failed)

Although, reinstalling the Exchange Server and IIS may fix this problem, but it can not repair the corrupted Exchange Server database. In order to repair and restore the damaged EDB file, you need to use third-party Exchange Recovery Software.

The applications are particularly designed to carry out systematic scan of entire EDB file (using advanced scanning mechanisms) and to extract all damaged and inaccessible objects. They enable you to perform Exchange Recovery on your own, as they have simple and self-descriptive graphical user interface.

Exchange Mailbox Recovery software repairs damaged EDB file and restores all user mailboxes as individual PST files. The Exchange Database 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, journals, appointments, and attachments.
