Hello Rob,

Diskeeper® performance software works safely and effectively with email servers. Diskeeper is designed to run in the background while these applications are operational and available to users. There is no need to stop or shutdown these applications or services to defragment.

Diskeeper prevents most of the writing of files in pieces to the disk and does so invisibly. What little gets by is instantly optimized before it can affect productivity or cause a proliferation of unnecessary I/Os.

Over a period of time, any popular email application server will experience this "internal" fragmentation of its database. This is where records are removed, but the space it occupied within the database is still there and is either reused for a new record or must be skipped over. It is important to state that Diskeeper does not, under any circumstances, restructure or alter the internal contents of any file.

The tools for Microsoft Exchange (ESE and EDB Utilities) deal with this internal record fragmentation by rearranging the internal records/indexes on the fly when possible, and at times requiring a whole new copy of the database to be created and each record copied to the new file.

So use the Microsoft tools to keep internal fragmentation at bay. Use Diskeeper to keep the external file defragmented.
