Exchange Server is a popular e-mail communication server. These days, almost all big organizations are implementing it as their main mail server. When any problem occurs in Exchange Server, it logs the troubled event IDs in the application log along with their system diagnosis. In general, the reason behind most of the error messages, is the corruption of Exchange Server database and this corruption leads to the inaccessibility of Exchange Server database. Well, data loss can be overcome, if you have the latest backup of your data. However, if backup is not available, then you need to go for a third party Exchange Server recovery software.
In respect of the above issue, let us consider a practical case. Suppose, your Microsoft Exchange 2003 server has got locked for no reason. And, when you rebooted the Server, you failed to start that up. On viewing the application event log, you saw the following event IDs on the screen:
“Event Type: ErrorEvent Source: MSExchangeISEvent Category: GeneralEvent ID: 9518Date: 6/7/2005Time: 5:56:43 PMUser: N/AComputer: CRC2K3Description:Error Log file is corrupt starting Storage Group/DC=local/DC=cr/CN=Configuration/CN=Services/CN=MicrosoftExchange/CN=CityRealtyMail/CN=Administrative Groups/CN=First AdministrativeGroup/CN=Servers/CN=CRC2K3/CN=InformationStore/CN=First Storage Group on theMicrosoft Exchange Information Store.Storage Group - Initialization of Jet failed.Event Type: ErrorEvent Source: MSExchangeSAEvent Category: MAPI SessionEvent ID: 9175Date: 6/7/2005Time: 6:07:09 PMUser: N/AComputer: CRC2K3Description:The MAPI call 'OpenMsgStore' failed with the following error:The Microsoft Exchange Server computer is not available.

“The database files in this store are corrupted”Reason: The primary cause, which is responsible for the occurrence of above error message is the corruption of the Exchange Server database. Corruption occurs because of unexpected system shutdown, operating system failure, human error, application malfunction etc.
How to solve ? : In order to solve the above problem you need to apply soft repair method first. Follow the following steps to perform the soft repair process:
1) Run the following commands to check the consistency of database:
eseutil /mh ..\mdbdata\priv.edb > mypriv.txt
eseutil /mh ..\mdbdatapub.edb > mypub.txt
2) If any of the databases are found to be inconsistent, use the following commands to carry out the soft repair solution:
eseutil /r /ispriv
eseutil /r /ispub
3) Now use the steps listed in the MS KB article:
"How to recover from information store corruption"
