Clearing space off mail servers by moving mailboxes

[MaxDSP]

E2k3 running on Win2k3 server....moving mailboxes from one mail server to another on the same domain SHOULD clear up space on the old server, which would reflect the size of the mailbox correct?

Say the old server has 2 GB free...if I move a mailbox that is 500MB off that server onto another, free drive space should be shown as 2.5 GB free right?

I think you have to run a backup, so that it will feel safe in truely removing the mailbox.

you need to defragment the mailbox store to free up that space.
Check eseutil on exchsrv\bin directorie.

Type on command prompt eseutil /? and check the parametersm but it will be something like eseutil /d "database name".

Becouse you dont have free space on the disk you will to provide some storage (ex a mapped network drive) and run the parameter /t to define a temp drive.
Exchange need 110% of the database size to defragement it.

Thats what I was afraid of...had to happen this week

Thanks for the info!

Thats an offline defrag. So plan accordingly. You can do it across to a networked drive, IIRC we had done that at one time due to the space contraints on a system. Much slower but it should work.

With 2K3, I'd assume the online defrag is on the same schedule as in 5.5 and 2K. All that does is move data forward in the database for better transfer speeds.

Backup your current DB, then test the backup, then do an offline defrag. Trust me, if you get any corruptions in that jetdirect DB and you have to do a hard repair.... Ohhh that's bad mojo my man, BAD MOJO.

I really wanted some alternatives to the offline/online backups I've read about, but looks like they are my only option.

Say the DB store is 25GB, I would need about 27GB of space right? About how long would an online defrag take?

MS info link

link no time though

Edit: Sorry didn't add that doing the online defrag won't recover any open space. It will just shift information to the front of the DB. You will still have the white space in the database. Offline is your only option. Why exact do you need to recover space? Users gone, almost out of disk space?

Where are your priv, pub, dir, and log files located?
