Exchange Priv1.edb and Priv1.stm

My Exchange 2003 Exchange file Priv1.edb size is 43,518,856, and the Priv1.stm is 41,533,448.  I heard there is a utility that decrease the size of the .stm file.  What would this utility be, and is it difficult to use.

EDB database technology the only way to shrink the physical size is to use the ESEUTIL /D command, generally it is safe, all you need to do is ensure that you have a full good backup of your Exchange database prior to running ESEUTIL. You will also need to ensure that you have about 110% of the size of your database free on the drive to defrag the DB. Have a look here for full instructions http://support.microsoft.com/kb/192185 it is not recommended that ESEUTIL is run as a matter of schedule (e.g. once a week) but I would typically run ESEUTIL on my databases every 6 months or so (we use Enterprise Vault) therefore we end up with large amounts of whitespace.

Here is some info of how to make a offline defrag of exchange databases.


This two files make the exchange database file. The database file is the sum fo both files.
    * Priv1.edb: A rich-text database file containing message headers, message text, and standard attachments.
    * Priv1.stm: A streaming internet content file containing audio, video and other media that are formatted as streams of Multipurpose Internet Mail Extensions (MIME) data.
