I will be moving mailboxes from one mailbox store to the newly created one in order to free up the whitespace of the old store. i moved a few of the mailboxes over and some stopped and only moved about a 1gb of email. when i resume the download again will the info be moved to the same mailbox, is it going to override and delete the previously moved email. ( my biggest concern) any help will be greatly appreciated

if it fails during the move it wont move anything and the mailbox will all be left on the original server, attemp to move it again

why are you not perfoming a offline defrag?

If you have 150gb of email to move, I know which I would prefer to do - move the mailboxes. At least you keep the server up. Try do an offline defrag of 150gb - that is something like two - three days total downtime.

Move mailbox is actually copy mailbox delete the source. So therefore if you cancelled the move then the data remained in place on the old server.

One of the moves has been interrupted. It moved about a GB of info to the new mail store, and left an original intack at 4gb when it was 5. when i move the mailbox over again is it going to move to the same destination mailbox or overide and delete the previous one which is what i am worried about.

Look in the log and find the corrupted item. Move Mailbox will fail on a single corrupt item. When you remove the item you need to hard delete it (SHIFT DEL).
The log will be in XML, but if you look carefully you can see the path, subject, sender and date of the corrupt item.

You can't use anything else to move the mailboxes, such as exmerge as it will fail on the same corrupted item. In many cases I find that it is the same item in a number of mailboxes that causes the problem.

With Exch2K3 you can select how many corrupted items to skip to allow the move to continue which will delete the corrupted item for you. Understood that you don't want to lose to much data but if moving is your only option then it makes since to set the number of items to skip high enough to allow the box to move.
