Why do we need to perform Exchange defrag?

With weekend round-the-corner, MS Exchange administrators often think about performing Exchange defrag. Going for Exchange defrag is quite a common activity in organizations using MS Exchange Server.

The latest versions of Exchange Server perform basic defragmentation on their own but here we refer to Exchange offline defragmentation.

Exchange Defragmentation or the subsequent compaction of your Exchange Server databases enables the operating system to regain disk space that was previously occupied by deleted Outlook data.

You must be wondering, “How all this happens?” Let’s see what happens and what leads a user to perform Exchange defrag?

At the time when users delete emails from their MS Outlook email client, the Exchange Server application empties the space within the data stores where the emails are stored but actually these never return the original on-disk storage space of emails to the operating system. The data store so created as a result of this never reduces in size.

When your Exchange data store consumes large quantities of disk space, then the only way left to regain that space for further productive work, is to perform an Exchange defrag or compaction process.

Exchange administrators defrag Exchange data store with the ESEUTIL utility produced by Microsoft, but the Exchange defragmentation with ESEUTIL proves to be a cumbersome and prolonged process.

ESEUTIL is surely not for someone who doesn’t have in-depth technical knowledge. This software is developed by Microsoft for manually defragmenting Exchange information stores and directories offline.

This Microsoft tool supports almost all the latest versions of Exchange Server right from Exchange 5.5. However, this utility must not be used before creation or verification of Exchange data backup copy.

Performing Exchange defrag using ESEUTIL, one needs to go through with a lot of manual commands and data entering that might be error prone.

Defragmenting an Exchange store accelerates the performance of Exchange Server to great levels. Defragmenting data lets you locate storage data, shrink Exchange database and reduce unused storage space.

Not taking care of your important data might lead you towards a number of data corruption situations. Save yourself from the disaster of data loss and keep your Exchange database healthy.
