Microsoft Exchange Server is one of the most powerful email servers used by many organizations to enhance the email facility provided by the MS Outlook application. It integrates the agile Extensible Storage Engine (ESE) & security-enhanced information store to offer smooth email communication.

After looking at the built-in database of the Exchange Server, one will clearly understand the information store is basically comprised of STM & EDB files.

In addition to this, Microsoft Exchange Server maintains the default mailbox storage database as Priv1.edb & Priv1.stm files. On the other side, Pub1.edb & Pub1.stm maintains all information of the email related to the default public store. Always keep in mind that EDB file is an ESE database keeping all-important email along with attachments and MAPI messages.

However, there are some situations due to which Exchange Dirty Shutdown state arises and damage Pub1.edb mailbox. As discussed above, the Pub1.edb file is the most crucial database file so, any damage in this can affect the complete Exchange Server very badly.

Therefore, after understanding the cause of corrupt EDB file, different methods to repair Public EDB file error & recover Pub1.edb mailboxes are discussed.

Reasons Behind Corrupt Pub1.edb Mailbox or Exchange Dirty Shutdown State

Corrupt Pub1.edb Mailbox due to Jet Engine Error

If the Exchange jet engine error occurs, it results in the corrupt Pub1.edb mailbox. The main reason behind the Jet engine errors is hardware or software crash. It can damage the different levels of the Exchange Server database. Therefore, if the Jet engine error occurs, then corruption can be at the following level:

  1. Jet database engine
  2. Exchange Server information store
  3. Exchange Server file system

Exchange Dirty Shutdown State

There are various situations in which Exchange Server is not able to perform the shutdown procedure normally. It can be due to any of the reasons discussed reason below:

  1. Unavailability of power backup results in an unexpected power failure
  2. An unreliable shutdown process while restoring emails.
  3. Due to sudden errors in the hard drive sector

If any of the above reasons occur, it becomes difficult for the Exchange Server database to isolate itself from transaction log streams that affect the integrity & consistency of the database.

At this point, if someone tries to restart the Exchange Server services, then the server first looks for the missing data log files. If the files went missing, it generates an Exchange corruption situation.

If any of the above two situations occur both Public & Private EDB mailboxes are always suffered from the lowest level corruption of Exchange database and deeper into the Exchange information store.
