With Exchange Server 2000 and 2003, every Mailbox store comprises a database set consisting of two files: ‘Priv1.edb’ and ‘Priv1.stm’.

The ‘Priv1.edb’ file is more like a rich-text database that primarily includes email messages, headers and text attachments corresponding to the messages. Moreover, this file also has streaming file ‘Priv.stm’ that majorly stores multi-media data like video, audio, images and other internet content files that is formatted as MIME data. The real issue with ‘Priv.edb’ file is its size keeps on increasing, which ultimately makes it susceptible of getting corrupt. In addition, Hard disk corruption and header corruption are other key causes accountable for corrupting the ‘Priv1.edb’ file. However, you don’t have to worry as there is a manual method to recover the corrupt Priv1.edb file.
