This is the last option to claim the white space but make sure you should 110% space available and good backup. The good practice is move the mailboxes to new stores which will ask you very little time for downtime per mailboxes.

I am assuming you need to perform an offline defrag to reclaim space on the drive. But did you make sure that the database has enough of white-space available ?? Check for event id 1221 and it should tell you. Now, runnning it on a different machine is never been easier. There is a great kb article on it How to run Eseutil on a computer without Exchange Server: http://support.microsoft.com/kb/244525/ You just need to copy and paste these files to a location and run it from there. Eseutil.exe, Ese.dll, Jcb.dll, Exosal.dll, and Exchmem.dll Now, the real question, what after offline defrag ??? As soon as you copy and paste the defragged database to production, these might happen. 1. Blackberry user might get garbled messages in inbox. 2. Outlook users might complain of Outlook being slow and some duplicate entries. 3. This issue would get resolved, if you reconfigure their profile. Troy,

I was told that the eseutil is a stand alone program and that I would have no problem stoping the store and copying the files to another server to run the defrag and then copying the files back. Do you see any issues with this? Thanks. Ratish or anyone else,

(concept of RSG and merging of data). **note** when there is change in database some user using other than OL 2003 SP2 or later may need to create new profile i think the time frame is not exact it actually depends on the database like 4- 5 GB per hour it actually varies it takes even more or even less . if Defrag is really necessary and we need the production as well we can have a dial tone strategy …… (concept of RSG and merging of data).

In couple of Exchange Master Certification Trainings i was advised by Exchange Rangers group to perform an offline defrag at least once every quarter. If the Exchange Database is designed by MS best practices ( Exchange 2003 50GB / per MBDB & Exchange 2007 100GB / MBDB) it does not take awfull long time to perform Eseutil /p , Eseutil/d. Ratish,
