asked on Offine defrag of exchange database
Hello,
I wanted to find out if there is a way to do offline defrag of a single database and keep rest online. We are running Exchange 2007 currently have 4 databases.
EX Database and Mailbox database are on the same disc, Ex DB size is 350 GB and Mailbox DB size is 1.07 TB.
MB3 and MB4 are on two separate discs.
I would like to defrag just Mailbox DB (1.07 TB) I have moved all mailbox to other DB except two which are 50 GB and 2 GB rest is empty space.
Mailbox Database" has 1072331 megabytes of free space after online defragmentation has terminated.

best thing to do is create a new mailbox and just move what you need, saves the hassle.

but yes here are instructions for offline defrag in exchange 2010
ESEUTIL instructions with technet link https://technet.microsoft.com/en-us/library/aa998863(v=exchg.80).aspx
As mentioned in my first post, was first with the suggestion, create as many mailbox databases as you need and migrate mailboxes into them. then wipe down your old database.
technet docs available for all tasks.

Mark and Seth you both are correct on moving two mailboxes to another database, the only thing holding me back is how long will it take to move 50 GB mailbox but defrag probably will take longer as well.
defrag is messy too, best avoided if possible.
just move them mailbox by mailbox out of hours if needs be, worth the sacrifice for me, cant remember if 2007 allows online migration like 2013. I do not believe it does off the top of my head.
Yes both correct, but one answered first.

Seth is a solid poster on here in fairness, he has beat me to the punch a few times on here. He is also a really good expert.
Good luck and watch out for arbitration mailboxes, they have to be moved too.

Dont be scared, it is a easy and mundane task to do this. I know it seems scary. Just ensure of image backups.

Sorry, I know a question is closed but I have one last question to ask. Is there a way to move a mailbox to another database while end user still has access to it?
Thank you
