Online Defragmentation Does Not Reduce Size of .edb Files

This article was previously published under Q256352
In Exchange 2000 Server and Exchange Server 2003, online defragmentation recovers disk space but does not reduce the size of an .edb database file.
To reduce the size of the .edb database file, you must perform an offline defragmentation with the Eseutil.exe utility (the eseutil /d command) against the .edb database file.

Note Online defragmentation does not reduce the size of .stm and .edb files.For additional information about defragmentation, click the article number below to view the article in the Microsoft Knowledge Base:
