As we all know that Exchange Server
use EDB and STM files to store its data. Exchange Server stores all
its default mailboxes in Priv1.edb and Priv1.stm files. There are
many tables in .edb file that contains meta data for all e-mails and
other items in the Exchange store.
Database(EDB+STM)+Entries in
transaction logs(LOG File)= Current Database
By the corporate perspective EDB file
in the Exchange server is the most important part because it consists
all required or non required files and folders thats why there are
many chances of corruption. EDB file stores all mailboxes with their
whole items like attachments, emails, calender events, etc. Or once
it will corrupt you have chance to loose all data.
If such type of any occurrence happen
like virus attack, hardware-or software failure, and sudden power
failure etc and because of that your EDB file get corrupted, no need
to worry there are many methods for repairing EDB file and
the recovery of its data.
