Hi Joe
The best way is to use "ESEUTIL" command on Exchange 2003 prior to upgrade on Exchange 2007. It will repair all corrupted items in database, you can reffer on this link
If you don't wanna use this procedure, you can repair single mailbox. Procedure is described here
Good luck

How do you know any items are corrupt, have you tried moving the mailboxes to Exchange 2010 and it failed?
Or are you trying to confirm that there are no corrupt items before migrating your users?

Try exmerge the mailbox out to PST. Exmerge will log any corrupt items and will skip them.
