The email delivery system at organization’s level is restricted to MS Outlook and Outlook Express. Although there are number of platforms that provide the same service but at the same time they are not preferred at large scale. It is known that the email exchange between client and user comprises duplicate copy of every mail. Thus, it acts as a backup copy of sent mail containing every detail.

During the failure of network connection when user tries to send the mail, the mailbox registers the action as ‘sent’ while keeping the copy intact. Whenever server connection is established the email exchange is done keeping a copy of mail on exchange Server. This processed called OST file synchronization. Once OST file synchronization is established it is time to secure the exchange server.

How secure is OST file in Exchange Server?

In Exchange Server the chances of corruption are at par with corruption in user system. Exchange Servers are sensitive towards corruption like:

The repair must be done swiftly as probability to recover damaged OST files is low when third-party tool is implemented.

Securing OST files
