Causes for Exchange Database Corruption

Fixing a problem starts with understanding and finding the reason for the problem. Your EDB file can corrupt due to the following reasons:

Hardware Issue: A hardware issue like a hard drive malfunction, motherboard issue, overheating, etc., can cause the Exchange Server to crash. These crashes can create various issues like corruption within the Exchange database.

Oversized EDB file: The database file contains multiple mailboxes for different users. Gradually, the size of the EDB file increases. If the EDB file size exceeds an allocated limit, the server may fail to mount the database, which can lead to database corruption.

Software Issue: A recent system update or installation of new software might be interfering with the operation of the Exchange database. Third party applications may prevent the server from utilizing the system resources to run smoothly.

Improper Server Handling: Not following the safety guidelines of the Exchange Server, improper shutdown, frequent power failures, etc., can cause integrity and other issues in the EDB file. Continuous negligence with the Exchange Server will lead to permanent damage.

Virus/Malware Attacks: You must always be on the lookout for virus attacks and have the latest security mechanism available on your system. Malware can damage your database file, making every mailbox content inaccessible.

Corrupted Log File: Database creates logs for every transaction it performs. These log files are important for data integrity and data restoration. Damage to these log files will interfere with the normal functioning of the database.
