Is it safe, and possible, to reduce the size of the Exchange informations stores by using Diskeeper, a third party defragmentation software?

    Accepted Solution


    No third-party defragmentation software will allow you to defrag the actual Exchange Database files. Only the eseutil tool can help you with that, but it's only absolutely necessary if you have deleted gigabytes of data out of the Exchange mailboxes, and then want to reclaim that space on the Exchange Server.

    If you run a defrag program on an Exchange Server's hard disks, that is not a problem and it is most definitely 'safe'. However, to prevent disk I/O growing out of control and causing Exchange to snarl up, I'd suggest you consider stopping the Exchange stores prior to running the defrag procedure. This will ensure Exchange does not try accessing the disks while the defrag tool does, and will also reduce the changes of any corruption occurring so there is virtually no risk involved.

    Running a disk defrag tool on a hard drive with the Exchange database on it will not actually improve the performance of the database either, due to the way the Exchange database works.
