A command-line tool for versions 4.0 and 5.0 of Microsoft Exchange Server. Edbutil can be used to defragment, repair, and check the integrity of the following Exchange Server databases:
Edbutil works at the Joint Engine Technology (Jet) level and attempts to find and repair inconsistencies. It can also be used to defragment these databases, resulting in a database size reduction.
In Exchange Server version 5.5, the edbutil utility has been replaced by the newer tool eseutil.
Use this utility with caution, and make sure that you have backed up the information store and directory databases first! Microsoft recommends using this utility only when troubleshooting Exchange Server problems in consultation with Microsoft Technical Support.
