Usually, when corruption occurs in MS Exchange Server 2000 and MS Exchange Server 2003, the Information store is an affected component. Information store comprises of following database files:
Priv1.edb contains database of files which are in-process and stores non-STMP messages. The Priv1.stm file contains Simple Mail Transfer Protocol (SMTP) mail messages, i.e. those emails are in-process and those stored on the server. Pub1.edb database files comprise of public folder store for non-SMTP formatted data and Pub1.stm consists of public folder that store SMTP formatted information.
Generally, corruption comprises of one or both .EDB (Exchange Server 2000 and Exchange Server 2003 database) files. In most cases, either the Priv1.edb file or the Pub1.edb file (both located in Program Files\Exchsrvr\Mdbdata folder) is corrupted.
