Mike, The syntax is correct. Don't you implement storage quotas for your users, 
so that you don't have to worry about a surprise store dismount. Also, consider 
the time it will take to defrag the 12GB database, depending on your hardware, 
and plan accordingly. Make sure your temp drive has at least 12GB free space.

Subject: [exchangelist] Defraging EDB files

Hi gang!

When I check the size of our EDB files in the MBDATA folder on our Ex2k/Win2k 
server, it's telling me my Priv.edb file is just over 12Gigs.  But when I check 
the Event Viewer for the online defrag that runs nightly, it's telling me I 
only have 270megs of space free in the mailbox store.  So, I'm assuming I 
better run a offline defrag SOON before my Exchange database reaches its 16 gig 

I have to admit, I'm real nervous running the offline defrag and just want to 
make sure I have the correct command before running the offline defrag.  Just 
so you know,
I don't have enough disk space on the same drive that Exchange is on.

In Exchange System Manager, right-click the information store that you want to 
defragment, and then click Dismount Store.

At the command prompt, change to the Exchsrvr\Bin folder

To defrag the priv.edb, enter the following;

eseutil /d /p "e:\exchsrvr\mdbdata\priv.edb" /t"f:\tempdfg.edb"

If there's anything else I should be aware or concerned about, please let me
