Defragmenting an Exchange database involves reorganizing the data to optimize storage efficiency and improve performance. Over time, as emails are added, deleted, and modified, the database can become fragmented, leading to slower access times and increased storage requirements. The process typically includes offline defragmentation using tools like Eseutil, which compacts the database by removing empty pages and consolidating data. This helps reduce the database size, enhance read/write operations, and improve overall server performance. Regular maintenance, including defragmentation, is essential to ensure the Exchange server operates smoothly and efficiently.
