Although Eseutil utility has a lot of merits there are some loopholes as well. One limitation of the Eseutil utility is that it can be run against only one Exchange database at a time. Another drawback is that it supports only offline defragmentation and does not support online defragmentation. Moreover, another limitation is that it can repair and restore EDB files with less corruption. This simply means that if the EDB file is highly corrupt or damaged, the Eseutil utility will be unable to resolve the corruption.

Free and Manual Way to Repair Exchange Database by EseUtil Utility

In order to maintain the Exchange Server database, online defragmentation is an activity that is done automatically on a regular basis. Online defragmentation improves the database performance as it removes the objects that are not in use, from the EDB. Although online database defragmentation is a part of database maintenance, sometimes it leads to the generation of a number of errors that display some sort of EDB corruption, the existence of uncommitted logs, and many other issues. Once the online defragmentation is over, if there are any errors then you need to perform EDB repair and recovery. One of the error messages that appear after the online defragmentation is mention below:

“1067 The Information Store terminated abnormally”

During the online defragmentation, when some sort of issue forces the Information Store to stop abruptly, this error message appears. However, if you want to know why the Information Store has terminated abruptly, you need to check the Event Log. When you check the Event log, you get the following information:

“Date: date Source: ESE

Time: time Category: Database Corruption

Type: Error Event ID: 447

User: N/A

Computer: Servername

Description: Information Store (nnnn) A bad page link (error -338) has been detected in a B-Tree (ObjectId: 70950, PgnoRoot: 157120) of database C:\Program Files\exchsrvr\mdbdata\priv1.edb (157120 => 296404, 296403).”

Once you read the above-mentioned error message in the Event log, you can easily understand the cause for the termination of the Information store.

As mentioned in the Event Log, the reason behind this error is EDB corruption. Considering database corruption as the main cause for this issue, let’s see how to perform EDB repair. One can repair the Exchange database either by using Eseutil Exchange Recovery tool.
