I am trying to gauge how long it is going to take to run eseutil on an edb that is about 20 GB. I copied the edb and the specified files (Eseutil.exe, Ese.dll, Jcb.dll, Exosal.dll, and Exchmem.dll) from the exchange server to my local hard drive and when I execute the commands at the prompt but it is telling me that it can not find the stm file. Can I run the eseutil on the edb without the stm file? If not, I gather that I need to make a copy of the stm file and run the eseutil then.Is this the case or is there a switch I can use to run it without the stm file?Any assistance is appreciated.

No, you need to have associated stm file to defrag the database. You can recreate stm file in your case. How to re-create STM File in Exchange 2000/2003 http://support.microsoft.com/kb/555146 BTW, defragmentation normally runs at 8-10GB/hour rate but also depends on hardware configuration and white space available in database. I have seen cases there it completes 20GB in an hour if it has large amount of white space. Amit Tank | MVP Exchange Server | MCITP:EMA MCSA:M | http://ExchangeShare.WordPress.com

Agree with Amit on this. It is highly recommended that you should run eseutil /d and ISINTEG on the database after your successfully complete with eseutil /p.eseutil /p actully repair the b-tree structure of the database and it repairs the physically corruption of the database, but if there is any logical corruption that can be repaired only by ISINTEG.Arun Kumar | MCSE - 2K3 + Messaging | ITIL-F V3
