When you install Microsoft Exchange Server 2007, a set of tasks is run to install few services. One of these services is Microsoft Exchange Transport Service, which is a network service responsible for SMTP and transport stack. At times, you observe that the service fails to start. Among other reasons, one root cause of this problem is corruption of ESE ( Extensible Storage Engine) database. This occurs when the corrupted database exists on Edge Transport Server or Hub Transport Server and has been serving as Content Filtering database or message queue database. This clearly means corruption and calls for actions to apply EDB Recovery solutions.

For more clarification of the issue, let's consider a problem when you attempt to start Microsoft Exchange Transport Service, but fail to do so. Further, on viewing the application log, you encounter the below event ID logging:

A storage group in Microsoft Exchange Server Information Store contains one or more mailbox stores, depending on the version of Exchange Server you use and requirements of the organization. Mailbox stores are the most critical components from data preservation perspectives as they comprise of system and user mailboxes. If corrupted, mailbox store causes serious problems in the working of an organization. A mailbox store is further comprised of two files, namely Priv1.edb and Priv1.stm. Corruption usually affects Priv1.edb file and occurs because of typical reasons like, database dirty shutdown, anti-virus software scan, virus infection, and network issues. When corrupted, EDB file on being accessed, prompts errors under a few event IDs, which can be read from application event log. Following is one such event IDs that generally occurs because of database corruption and requires EDB Recovery solutions...

Is your Exchange Server database inaccessible due to corruption of the Information Store? Are you getting Jet Database Engine errors while restoring database from backup? Information Store is the most commonly affected Exchange Server component, when database corruption occurs. Corruption generally occurs in Priv.edb or Pub.edb, that are located in ExchSrvr\Mdbdata directory on server. EDB (Exchange Server Database) is an extension of Exchange Server database file. In case of corruption, the database becomes inconsistent and Exchange Server can not read data from it. It leads to significant data loss situations and needs EDB Recovery, if you do not have an updated backup in place. Microsoft Exchange Server indicates Information Store corruption with a number of symptoms, which include:

1. You can not start Microsoft Exchange Server Information Store Service.

2. The Information Store Service can not be stopped...

This behavior of MS Exchange Server renders all your valuable data inaccessible and cause critical data loss situations. In order to get your precious data recovered in such situations, you need to repair and restore the damaged EDB file, using an EDB Recovery solutions.
