Exchange Server Recovery

Microsoft Exchange Server is an email server application used by companies to handle their email, contact and calendar data from a centralized location. The entire Exchange server data gets stored in the form of EDB files that can be many GB's in size. Any unfavorable event can cause corruption of these Exchange database files. It can make Exchange Server mailboxes inaccessible to users.

Components of Exchange Database (EDB) file –

Exchange EDB file is made up of server component which is based on the standard database technique. This email server system has embedded database engine, which lays out structure of disk of the Exchange Server. Major components of EDB file are as give below:

Information Store:This is the key component of server; it has two separate databases - private information store and public information store. It works with MAPI and database engine to make sure that all operations are stored on server hard drive.
JET Database Engine:Exchange databases are based upon JET format that uses log files to maintain and track information. It collects information and store them in systematic way.
Corruption in Exchange Database –

Like other database files, Exchange server EDB database is also very susceptible to any unfavorable events occurring to your system. Exchange server administrators often come across such issues which usually occur due to virus infection, improper system shutdown, application malfunction, user errors and missing database objects. There are two main types of database corruption, which require Exchange Repair to be resolved:

Internal or Logical Corruption: Such errors occur due to damaged or missing database objects such as database engine failure and information store corruption. This type of corruption could also occur at application level in folders, mailboxes, messages and attachments.
External or Physical Corruption: This type of corruption errors occurs when entire database gets damaged on the hard drive.

To overcome such Exchange server corruption situations, Exchange provides two repair tools - Eseutil and Isinteg. These utilities help you to repair, recover and restore corrupt database in minor situations. Before applying these utilities, you must create a backup of existing EDB database if it is possible as it may harm your database. In case of severe EDB corruption issues, these utilities get fail.

Method 1: Removal of all affected database files and mount affected store: This method is very fast for restoring services for the user and makes the previous data available easily. However, there is a chance of data loss.

If you have created role group using Exchange Management Shell, you should not use Exchange Admin Center to define new role to the existing role group.

As a quick fix when your server is running out of space because of the large size of the EDB files, you can manually try this:

Begin by creating a new Mailbox database and then move the data from Old Mailbox to New Mailbox. Now, shrink the Database files by performing Offline defragging them. Finally move the location of the Mailbox Database.
