Hi,

My exchange servers database is having some problems and i have to run offline defrag on it but my users can not afford 10 hours long messaging unavailability. As a work around i m going to create a fresh and new store and will point all users into it untill defrag is running on existing store.
Please let me know any smart and short way to configure this new store for all 200 users because doing it from ADUC will take long time.
I have exchange 2003 enterprise with SP2.

You would be better off creating a new mailbox database and moving mailboxes at night
then remove the original database

OK, but what will happen during mailbox movement ? I think it will transfer all the mails reside in each mailbox to that new mailstore and if total size of my users mailboxes is 60 GB, it will take around 15 hours while my defrag will also consume same amount of time so there is no logic to create new mailbox and movement etc etc.

I hope u understand...

users will only lose access to their mailbox while their mailbox is being moved
hence instead of a 10 hour outage for all of your users, you may have a 30 minute outage per user (depending on the size of their mailbox)

i think you were hoping to use the dial-tone database in a way it is not designed
the dial-tone database utilizes the recovery storage group, and that is how it is possible
you cannot have two mailbox stores with the same name, so you would need to script rehoming all users to a blank mailbox (from a new mailbox store)
this requires too much administrative overhead, potential for issues, and users working from an empty mailbox
