One of the most common issues that an Exchange administrator has to face is Exchange database corruption. Although the latest versions of Exchange are quite stable, you cannot have a surety of a seamless Exchange database performance.

There are several reasons behind the corruption of Exchange databases that you need to understand and implement fixes accordingly. Some of the most common reasons for corruption are described below:

Reasons Behind Exchange Database Corruption

Hardware Failure – Having inadequate hardware is one of the major reasons why the Exchange database goes into a bad state. The bad sectors on a hard drive, overheating motherboard, and many other issues can be the reason for corrupted Exchange DB.

Server Failure – Another reason for Exchange DB failure is when the Exchange Server is shut abruptly. Additionally, any issues related to network, misconfiguration, or system overload might result in Exchange Server failure, hence resulting in corruption issues.

Accidental Shutdowns – If you know about the dirty shutdown state in Exchange Server, then the primary reason for that is a sudden shutdown of the system. Whenever the system is shut down accidentally, the Exchange Information Store fails to update transaction logs completely, hence causing inconsistency in the database.

Oversized Exchange Databases – Whenever an Exchange database exceeds the size limit beyond the limit mentioned in the registry, the Exchange database gets corrupt. In such cases, the Exchange database dismounts itself and creates further issues in working.

Boot Failure – Any kind of malware attack or some sort of failure in system services can result in Boot failure. This issue can also occur due to hardware malfunctioning or OS failure.

Human Errors – Last but not least, there are scenarios where the administrator is working on Exchange Server and makes an unintentional mistake. In these cases, you cannot avoid Exchange database corruption and eventually end up with a damaged DB.
