MS Exchange Repair Tool to repair corrupted or damaged edb file

Microsoft Exchange Server provides you with an inbuilt tool, called Exchange System Manager to manage the Exchange Server operations. It is a narrowed MMC console, which is automatically installed during Exchange Server installation. It helps you to mount the Exchange Server database and makes it accessible by the users. However, under some situations, the database can not be mounted using Exchange System Manager and you run across database inaccessibility. This problem is usually caused by corruption of the EDB (Exchange Database) file or Information Store. It leads to data loss and requires Exchange Server repair to be sorted out.

For example, you may run across the below error message after you restore the Exchange Server database from online backup and then try to mount EDB file using the Exchange System Manager tool:

“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”

At the same time, you may see the following entries in application event log of Microsoft Exchange Server:

“Event Type: Error
Event Source: ESE98
Event Category: Logging/Recovery
Event ID: 619
Description:
Information Store (nnnn) Attempted to attach database

restored from a backup set on which hard recovery was not started
or did not complete successfully.
