Exchange database (EDB) files are
designed to store all the information and folders. Exchange database
is the bonanza of all types of data. Corruption in Exchange database
may affect smoothness of working or may be due to this Exchange
server may refuse to open. Your each and every effort to access
database or user mailbox has to face failure since database is
damaged due to some unexpected cause. In layman language these cause
are called errors. To ignore these errors or to make Exchange database recoverable you can use previous backup file to
mount all essential data again on Exchange server.
