That would be correct. You do this during your quarterly or semi-annual maintenance period where you run ISINTEG (or GoExchange for all you "unreal" Exchange administrators) to ensure that you don't have any corruption festering in your databases.

A positive is that Exchange doesn't have to physically expand the database store when additional space is needed. Regards, Michael B.

Is there any benefit to running an offline defrag after you have migrated a significant amount of data from one database to another, other than regaining disk space? I recently migrated about half of my users (50GB) to another storage group (Exchange 2003 SP2) and was wondering if I should bother with defragging the original database. I'm not concerned about the size of the original DB as I have plenty of disk space. Sorry to hijack the thread but I figured it was relatively on-topic. - Sean On 3/25/08, Don Ely <[EMAIL PROTECTED]> wrote: Yes we do... On Tue, Mar 25, 2008 at 3:37 PM, Michael B.

In all so far I have moved about 120 gig of mailboxes to the other server but I do not see that space coming back on the first server. I do run the online maintenance of the databases that is built inside of the system manager. I also get emails nightly on what was done. Below is one that I got last night. I was under the impression that Exchange would clean itself up after the moves and allow the database to shrink after it ran the maintenance. Do I have something set wrong or is my thinking wrong. If my thinking is wrong do I need to do an offline defrag to get the space back?
