  • Hi Sudhir,

    We can currupt the .edb file by the following acts.

    • Exchange Server failure
    • Virus intrusions
    • JET engine errors
    • Corrupt header information
    • Exchange error messages
    • Accidental system shutdown
    • Hard disk errors
    • Installation of malicious software etc

    Due to EDB corruption, entire data stored on Exchange Server become inaccessible which is a serious threat to your mailbox data. EDB corruption demands instant action before your crucial mailbox data gets lost forever, then you can do the recovery process in your lab environment.

  • Open the database in a text editor and remove some random bits of content. That will make the database in an inconsistent state.

  • Hi

    What do you want to achieve?

    in real world scenarios VM's or physical servers go down without mention and can cause it.

  • Agreed that Shakir made an excellent post and also I am with others, i.e. wanting to know what you are trying to achieve will allow us all to offer more pointed advice, i.e. there are minor and major corruptions that require different actions

    Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline Exchange Mailbox and Public Folder EDB's and Live Exchange Servers or Import/Migrate direct from Offline EDB to Any Production Exchange Server, even cross version i.e. 2003 --> 2007 --> 2010 --> 2013 --> 2016 with Lucid8's DigiScope http://www.lucid8.com/product/digiscope.asp
